DERIVATIVESThe word “DERIVATIVES” is derived from the word itself derived of aunderlying asset. It is a future image or copy of a underlying asset whichmay be shares, stocks, commodities, stock indices, etc.Derivatives is a financial product (shares, bonds) any act which isconcerned with lending and borrowing (bank) does not have its valueborrow the value from underlying asset/ basic variables.Derivatives is derived from the following products: A. Shares B. Debuntures C. Mutual funds D. Gold E. Steel F. Interest rate G. Currencies.Derivatives is a type of market where two parties are entered into acontract one is bullish and other is bearish in the market having oppositeviews regarding the market. There cannot be a derivatives having sameviews about the market. In short it is like a INSURANCE market whereinvestors cover their risk for a particular position.Derivatives are financial contracts of pre-determined fixed duration,whose values are derived from the value of an underlying primaryfinancial instrument, commodity or index, such as: interest rates,exchange rates, commodities, and equities.Derivatives are risk shifting instruments. Initially, they were used toreduce exposure to changes in foreign exchange rates, interest rates, orstock indexes or commonly known as risk hedging. Hedging is the mostimportant aspect of derivatives and also its basic economic purpose.There has to be counter party to hedgers and they are speculators.Speculators don’t look at derivatives as means of reducing risk but it’s abusiness for them. Rather he accepts risks from the hedgers in pursuit ofprofits. Thus for a sound derivatives market, both hedgers andspeculators are essential.

Derivatives trading has been a new introduction to the Indian markets. Itis, in a sense promotion and acceptance of market economy, that hasreally contributed towards the growing awareness of risk and hence thegradual introduction of derivatives to hedge such risks.Initially derivatives was launched in America called Chicago. Then in 1999,RBI introduced derivatives in the local currency Interest Rate markets,which have not really developed, but with the gradual acceptance of theALM guidelines by banks, there should be an instrumental product inhedging their balance sheet liabilities.The first product which was launched by BSE and NSE in the derivativesmarket was index futuresBACKGROUNDConsider a hypothetical situation in which ABC trading company has toimport a raw material for manufacturing goods. But this raw material isrequired only after 3 months. However in 3 months the prices of rawmaterial may go up or go down due to foreign exchange fluctuations andat this point of time it can not be predicted whether the prices would goup or come down. Thus he is exposed to risks with fluctuations in forexrates. If he buys the goods in advance then he will incur heavy interestand storage charges. However, the availability of derivatives solves theproblem of importer. He can buy currency derivatives. Now any loss dueto rise in raw material prices would be offset by profits on the futurescontract and vice versa. Hence the company can hedge its risk throughthe use of derivativesDEFINATIONSAccording to JOHN C. HUL “ A derivatives can be defined as a financialinstrument whose value depends on (or derives from) the values of other,more basic underlying variables.”According to ROBERT L. MCDONALD “A derivative is simply a financialinstrument (or even more simply an agreement between two people)which has a value determined by the price of something else.

With Securities Laws (Second Amendment) Act,1999, Derivatives has beenincluded in the definition of Securities. The term Derivative has beendefined in Securities Contracts (Regulations) Act, as:-A Derivative includes: - a. a security derived from a debt instrument, share, loan, whether secured or unsecured, risk instrument or contract for differences or any other form of security; b. contract which derives its value from the prices, or index of prices,of underlying securities.Derivatives were developed primarily to manage, offset or hedge againstrisk but some were developed primarily to provide the potential for highreturns.INTRODUCTION TO FUTURE MARKETFutures markets were designed to solve the problems that exit inforward markets. A futures con tract is an agreement between twoparties to buy or sell an asset at a certain time in the future at a certainprice. There is a multilateral contract between the buyer and seller for aunderlying asset which may be financial instrument or physicalcommodities. But unlike forward contracts the future contracts arestandardized and exchange traded.PURPOSEThe primary purpose of futures market is to provide an efficient andeffective mechanism for management of inherent risks, withoutcounter-party risk.It is a derivative instrument and a type of forward contract The futurecontracts are affected mainly by the prices of the underlying asset. As itis a future contract the buyer and seller has to pay the margin to trade inthe futures marketIt is essential that both the parties compulsorily discharge theirrespective obligations on the settlement day only, even though thepayoffs are on a daily marking to market basis to avoid default risk.Hence, the gains or losses are netted off on a daily basis and eachmorning starts with a fresh opening value. Here both the parties face an

equal amount of risk and are also required to pay upfront margins to theexchange irrespective of whether they are buyers or sellers. Index basedfinancial futures are settled in cash unlike futures on individual stockswhich are very rare and yet to be launched even in the US. Most of thefinancial futures worldwide are index based and hence the buyer nevercomes to know who the seller is, both due to the presence of the clearingcorporation of the stock exchange in between and also due to secrecyreasonsEXAMPLEThe current market price of INFOSYS COMPANY is Rs.1650.There are two parties in the contract i.e. Hitesh and Kishore. Hitesh isbullish and kishore is bearish in the market. The initial margin is 10%.paid by the both parties. Here the Hitesh has purchased the one monthcontract of INFOSYS futures with the price of Rs.1650.The lot size ofinfosys is 300 shares.Suppose the stock rises to 2200. Profit 20 2200 10 0 1400 1500 1600 1700 1800 1900 -10 -20 LossUnlimited profit for the buyer(Hitesh) = Rs.1,65,000 [(2200-1650*3oo)]and notional profit for the buyer is 500.

Unlimited loss for the buyer because the buyer is bearish in the marketSuppose the stock falls to Rs.1400 Profit 20 10 0 1400 1500 1600 1700 1800 1900 -10 -20 LossUnlimited profit for the seller = Rs.75,000.[(1650-1400*300)] andnotional profit for the seller is 250.Unlimited loss for the seller because the seller is bullish in the market.Finally, Futures contracts try to "bet" what the value of an index orcommodity will be at some date in the future. Futures are often used bymutual funds and large institutions to hedge their positions when themarkets are rocky. Also, Futures contracts offer a high degree of leverage,or the ability to control a sizable amount of an asset for a cash outlay,which is distantly small in proportion to the total value of contractMARGINMargin is money deposited by the buyer and the seller to ensure theintegrity of the contract. Normally the margin requirement has beendesigned on the concept of VAR at 99% levels. Based on the value at riskof the stock/index margins are calculated. In general margin rangesbetween 10-50% of the contract value.

PURPOSEThe purpose of margin is to provide a financial safeguard to ensure thattraders will perform on their contract obligations.TYPES OF MARGININITIAL MARGIN:It is a amount that a trader must deposit before trading any futures. Theinitial margin approximately equals the maximum daily price fluctuationpermitted for the contract being traded. Upon proper completion of allobligations associated with a traders futures position, the initial margin isreturned to the trader.OBJECTIVEThe basic aim of Initial margin is to cover the largest potential loss in oneday. Both buyer and seller have to deposit margins. The initial margin isdeposited before the opening of the position in the Futures transaction.MAINTENANCE MARGIN:It is the minimum margin required to hold a position. Normally themaintenance is lower than initial margin. This is set to ensure that thebalance in the margin account never becomes negative. If the balance inthe margin account falls below the maintenance margin, the investorreceives a margin call to top up the margin account to the initial levelbefore trading commencing on the next level.ILLUSTRATIONOn MAY 15th two traders, one buyer and seller take a position on JuneNSE S and P CNX nifty futures at 1300 by depositing the initial margin ofRs.50,000with a maintenance margin of 12%. The lot size of nifty thfutures =200.suppose on MAY 16The price of futures settled at Rs.1950. As the buyer is bullish andthe seller is bearish in the market. The profit for the buyer will be 10,000[(1350-1300)*200]Loss for the seller will be 10,000[(1300-1350)]Net Balance of Buyer = 60,000(50,000 is the margin +10,000 profit forthe buyer)Net Balance of Seller = 40,000(50,000 is the margin -10,000 loss for theseller)

Suppose on may 17th nifty futures settled at 1400.Profit of buyer will be 10,000[(1450-1350)*200]Loss of seller will be 10,000[(1350-1400)*200]Net balance of Buyer =70,000(50, 000 is the margin +20,000 profit forthe buyer)Net Balance of Seller = 30,000(50,000 is the margin -20,000 loss for theseller)As the sellers balance dropped below the maintenance margin i.e. 12% of1400*200=33600 While the initial margin was 50,000.Thus the sellermust deposit Rs.20,000 as a margin call.Now the nifty futures settled at Rs.1390.Loss for Buyer will be 2,000 [(1390-1400)*200]Profit for Seller will be 2,000 [(1390-1400)*200]Net balance of Buyer =68,000(70,000 is the margin -2000 loss for thebuyer)Net Balance of Seller = 52,000(50,000 is the margin +2000 profit for theseller)Therefore in this way each account each account is credited or debitedaccording to the settlement price on a daily basis. Deficiencies in marginrequirements are called for the broker, through margin calls. Till now theconcept of maintenance margin is not used in India.ADDITIONAL MARGIN:In case of sudden higher than expected volatility, additional margin maybe called for by the exchange. This is generally imposed when theexchange fears that the markets have become too volatile and may resultin some crisis, like payments crisis, etc. This is a preemptive move byexchange to prevent breakdown.CROSS MARGINING:This is a method of calculating margin after taking into accountcombined positions in Futures, options, cash market etc. Hence, the totalmargin requirement reduces due to cross-Hedges.MARK-TO-MARKET MARGIN:

It is a one day market which fluctuates on daily basis and on every scripproper evaluation is done. E.g. Investor has purchase the SATYAMFUTURES. and pays the Initial margin. Suddenly script of SATYAM fallsthen the investor is required to pay the mark-to-market margin alsocalled as variation margin for trading in the future contract

HEDGERS :Hedgers are the traders who wish to eliminate the risk of price change towhich trhey are already exposed.It is a mechanism by which theparticipants in the physical/ cash markets can cover their price risk.Hedgers are those persons who don’t want to take the risk therefore theyhedge their risk while taking position in the contract. In short it is a wayof reducing risks when the investor has the underlying security.PURPOSE:“TO REDUCE THE VOLATILITY OF A PORTFOLIO, BY REDUCING THE RISK”Figure 1.1 Hedgers Existing SYSTEMNewApproach Peril &Prize ApproachPeril &Prize1) Difficult to 1) No Leverage 1)Fix price today to buy 1)Additionaloffload holding available risk latter by paying premium.cost is onlyduring adverse reward dependant 2)For Long, buy ATM Putpremium.market conditions on market prices Option.

Advantages Availability of LeverageSTRATEGY:The basic hedging strategy is to take an equal and opposite position inthe futures market to the spot market. If the investor buys the scrip in thespot market but suddenly the market drops then the investor hedge theirrisk by taking the short position in the Index futuresHEDGING AND DIVERSIFICATION:Hedging is one of the principal ways to manage risk, the other beingdiversification. Diversification and hedging do not have have cost in cashbut have opportunity cost. Hedging is implemented by adding anegatively and perfectly correlated asset to an existing asset. Hedgingeliminates both sides of risk: the potential profit and the potential loss.Diversification minimizes risk for a given amount of return (or,alternatively, maximizes return for a given amount of risk). Diversificationis affected by choosing a group of assets instead of a single asset(technically, by adding positively and imperfectly correlated assets).ILLUSTRATIONRam enters into a contract with Shyam that he sells 50 pens to Shyam forRs.1000. The cost of manufacturing the pen for Ram is only Rs. 400 andhe will make a profit of Rs 600 if the sale is completed.COST SELLING PRICE PROFIT400 1000 600

However, Ram fears that Shyam may not honour his contract. So heinserts a new clause in the contract that if Shyam fails to honour thecontract he will have to pay a penalty of Rs.400. And if Shyam honoursthe contract Ram will offer a discount of Rs 100 as incentive.Shyam defaults Shyam honors400 (Initial Investment) 600 (Initial profit)400 (penalty from Shyam (-100) discount given to Shyam- (No gain/loss) 500 (Net gain)Finally if Shyam defaults Ram will get a penalty of Rs 400 but Ram willrecover his initial investment. If Shyam honors the bill the ram will get aprofit of 600 deducting the discount of Rs.100 and net profit for ram isRs.500. Thus Ram has hedged his risk against default and protected hisinitial investment.Now let’s see how investor hedge their risk in the marketExample:Say you have bought 1000 shares of XYZ Company but in the short termyou expect that the market would go down due to some news. Then, tominimize your downside risk you could hedge your position by buying aPut Option. This will hedge your downside risk in the market and yourloss of value in XYZ will be set off by the purchase of the Put Option.Therefore hedging does not remove losses .The best that can be achievedusing hedging is the removal of unwanted exposure, i.e.unnessary risk.The hedging position will make less profits than the un-hedged position,half the time. One should not enter into a hedging strategy hoping tomake excess profits for sure; all that can come out of hedging is reducerisk.HEDGING WITH OPTIONS:Options can be used to hedge the position of the underlying asset. Herethe options buyers are not subject to margins as in hedging throughfutures. Options buyers are however required to pay premium which aresometimes so high that makes options unattractive.

ILLUSTRATION:With a market price of ACC Rs.600 the investor buys the 50 shares ofACC.Now the investor excepts that price will fall by 100.So he decided tobuy the put Option b y paying the premium of Rs.25. Thus the investorhas hedge their risk by purchasing the put Option. Finally stock falls by100 the loss of investor is restricted t the premium paid of Rs.2500 asinvestor recovered Rs.75 a share by buying ACC put.HEDGING STRATEGIES: LONG SECURITY, SELL NIFTY FUTURES: Under this investor takes a long position on the security and sell some amount of Nifty Futures. This offsets the hidden Nifty exposure that is inside everylong- security position. Thus the position LONG SECURITY, SELL NIFTY isa pure play on the performance of the security, without any extra riskfrom fluctuations of the market index. Finally the investor has “HEDGEDAWAY” his index exposure.EXAMPLE:

LONG SECURITY, SELL FUTURES Here stock futures can be used as an effective risk–management tool. In this case the investor buys the shares of thecompany but suddenly the rally goes down. Thus to maximize the riskthe Hedger enters into a future contract and takes a short position.However the losses suffers in the security will be offset by the profits hemakes on his short future position.Spot Price of ACC = 390Market action = 350Loss = 40Strategy = BUY SECURITY, SELL FUTURESTwo month Futures= 390Premium = 12Short position = 390Future profit = 40(390-350)As the fall in the price of the security will result in a fall in the price ofFutures. Now the Futures will trade at a price lower then the price atwhich the hedger entered into a short position.Finally the loss of Rs.40 incurred on the security hedger holds, will bemade up the profits made on his short futures position. HAVE STOCK, BUY PUTS: This is one of the simplest ways to take on hedge. Here the investor buys 100 shares of HLL.The spot price of HLL is 232 suddenly the investor worries about the fall of price. Therefore the solution is buy put options on HLL. The investor buys put option with a strike of Rs.240. The premium charged is Rs.10.Here the investor has two possible scenarios three months later. 1) IF PRICE RISES Market action: 215 Loss : 17(232-15) Strike price : 240 Premium : 08 Profit : 17(240-215-8)

Thus loss he suffers on the stock will be offset by the profit the investor earns on the put option bought. 2) IF PRICE RISES: Market share : 250 Loss : 10 Short position : 250(spot market) Thus the investor has a limited loss(determined by the strike price investor chooses) and an unlimited profit. HAVE PORTFOLIO, SHORT NIFTY FUTURES: Here the investor are holding the portfolio of stocks and selling nifty futures. In the case of portfolios, most of the portfolio risk is accounted for by index fluctuations. Hence a position LONG PORTFOLIO+ SHORT NIFTY can often become one-tenth as risky as the LONG PORTFOLIO position. Let us assume that an investor is holding a portfolio of followingscrips as given below on 1st May, 2001.Company Beta Amount of Holding ( in Rs)Infosys 1.55 400,000.00Global Tele 2.06 200,000.00Satyam Comp 1.95 175,000.00HFCL 1.9 125,000.00Total Value of Portfolio 1,000,000.00Trading Strategy to be followedThe investor feels that the market will go down in the next two monthsand wants to protect him from any adverse movement. To achieve thisthe investor has to go short on 2 months NIFTY futures i.e he has to sellJune Nifty. This strategy is called Short Hedge.Formula to calculate the number of futures for hedging purposes isBeta adjusted Value of Portfolio / Nifty Index levelBeta of the above portfolio

=(1.55*400,000)+(2.06*200,000)+(1.95*175,000)+(1.9*125,000)/1,000,000=1.61075 (round to 1.61)Applying the formula to calculate the number of futures contractsAssume NIFTY futures to be 1150 on 1st May 2001= (1,000,000.00 * 1.61) / 1150= 1400 UnitsSince one Nifty contract is 200 units, the investor has to sell 7 Niftycontracts. Short Hedge Stock Market Futures Market st1 May Holds Rs 1,000,000.00 Sell 7 NIFTY futures in stock portfolio contract at 1150.25th June Stock portfolio fall by NIFTY futures falls by 6% to Rs 940,000.00 4.5% to 1098.25Profit / Loss Loss: -Rs 60,000.00 Profit: 72,450.00 Net Profit: + Rs 15,450.00SPECULATORS:If hedgers are the people who wish to avoid price risk, speculators arethose who are willing to take such risk. speculators are those who do nothave any position and simply play with the others money. They only havea particular view on the market, stock, commodity etc. In short,speculators put their money at risk in the hope of profiting from ananticipated price change. Here if speculators view is correct he earnsprofit. In the event of speculator not being covered, he will loose theposition. They consider various factors such as demand supply, marketpositions, open interests, economic fundamentals and other data to taketheir positions.SPECULATION IN THE FUTURES MARKET

Speculation is all about taking position in the futures market without having the underlying. Speculators operate in the market with motive to make money. They take: Naked positions - Position in any future contract. Spread positions - Opposite positions in two future contracts. This is a conservative speculative strategy.Speculators bring liquidity to the system, provide insurance to thehedgers and facilitate the price discovery in the market.Figure 1.2 Speculators Existing SYSTEMNewApproach Peril &Prize ApproachPeril &Prize1) Deliver based 1) Both profit & 1)Buy &Sell stocks1)MaximumTrading, margin loss to extent of on delivery basisloss possibletrading& carry price change. 2) Buy Call &Put topremiumforward transactions. by payingpaid2) Buy Index Futures premium

He study the market and play thegame with the stock marketTYPES: POSITION TRADERS:These traders have a view on the market an hold positions over a periodof as days until their target is met.

DAY TRADERS:. Day traders square off the position during the curse of the trading dayand book the profits. SCALPERS:Scalpers in anticipation of making small profits trade a number of timesthroughout the day.SPECULATING WITH OPTIONS:A speculator has a definite outlook about future price, therefore he canbuy put or call option depending upon his perception about future price.If speculator has a bullish outlook, he will buy calls or sell (write) put. Incase of bearish perception, the speculator will put r write calls. Ifspeculator’s view is correct he earns profit. In the event of speculator notbeing covered, he will loose the position. A Speculator will buy call or putif his price outlook in a particular direction is very strong but if is eitherneutral or not so strong. He would prefer writing call or put to earnpremium in the event of price situations.ILLUSTRATION:Here if speculator excepts that ZEE TELEFILMS stock price will rise frompresent level of Rs.1050 then he buys call by paying premium. If priceshave gone up then he earns profit otherwise he losses call premiumwhich he pays to buy the call. if speculator sells that ZEE TELEFILMS stockwill come down then he will buy put on the stale price until he can writeeither call or put.Finally Speculators provide depth an liquidity to the futures market an intheir absence; the price protection sought the hedger would be verycostly.STRATEGIES: BULLISH SECURITY,SELL FUTURES:Here the Speculator has a view on the market. The Speculator is bullish inthe market. Speculator buys the shares of the company an makes the

profit. At the same time the Speculator enters into the future contract i.e.buys futures and makes profit.Spot Price of RELIANCE = 1000Value = 1000*100shares = 1,00,000Market action = 1010Profit = 1000Initial margin = 20,000Market action = 1010Profit = 400(investment of Rs.20,000)This shows that with a investment of Rs.1,00,000 for a period of 2months the speculator makes a profit of 1000 and got a annual return of6% in the spot market but in the case of futures the Speculator makes aprofit of Rs.400 on the investment of Rs.20,000 and got return of 12%.Thus because of leverage provided security futures form an attractiveoption for speculator. BULLISH STOCK, BUY CALLS OR BUY PUTS:Under this strategy the speculator is bullish in the market. He could doany of the following: BUY STOCKACC spot price : 150No of shares : 200Price : 150*200 = 30,000Market action : 160Profit : 2,000Return : 6.6% returns over 2months BUY CALL OPTION:Strike price : 150Premium : 8Lot size : 200 sharesMarket action :160Profit : (160-150-8)*200 = 400Return : 25% returns over 2months

This shows that investor can earn more in the call option because it gives25% returns over a investment of 2months as compared to 6.6% returnsover a investment in stocks BEARISH SECURITY,SELL FUTURES:In this case the stock futures is overvalued and is likely to see a fall inprice. Here simple arbitrage ensures that futures on an individualsecurities more correspondingly with the underlying security as long asthere is sufficient liquidity in the market for the security. If the securityprice rises the future price will also rise and vice-versa.Two month Futures on SBI = 240Lot size = 100sharesMargin = 24Market action = 220Future profit = 20(240-220)Finally on the day of expiration the spot and future price converges theinvestor makes a profit because the speculator is bearish in the marketand all the future stocks need to sell in the market. BULLISH INDEX, LONG NIFTY FUTURES:Here the investor is bullish in the index. Using index futures, an investorcan “BUY OR SELL” the entire index trading on one single security. Once aperson is LONG NIFTY using the futures market, the investor gains if theindex rises and loss if the index falls.1st July = Index will riseBuy nifty July contract = 960Lot =200

14th July nifty risen= 967.35Nifty July contract= 980Short position =980Profit = 4000(200*20)ARBITRAGEURS:Ar bi t r age i s t he concept of si m t aneous buyi ng of secur i t i es i n one ulm ket w e t he pr i ce i s l ow and sel l i ng i n anot her m ket w e t he ar her ar herpr i ce i s hi gher .Ar bi t r ageur s t hr i ve on m ket i m f ect i ons.

STRATEGIES: BUY SPOT, SELL FUTURES: In this the investor observing that futures have beenoverpriced, how can the investor cash in this opportunity to earn risk lessprofits. Say for i nst ance AC = 1000 and One month ACC futures = 1025. CThis shows that futures have been overpriced and therefore as anArbitrageur, investor can make r i sk l ess pr of i t s ent er i ng i nt o t hef ol l ow ng set f t r ansact i ons. i On day one, borrow funds, buy security on the spot market at 1000 Simultansely, sell the futures on the security at1025 Take delivery of the security purchased and hold the security for a month on the futures expiration date, the spot and futures converge . Now unwind the position Sa y the security closes at Rs.1015. Sell the security Futures position expires with the profit f Rs.10 The result is a risk less profit of Rs.15 on the spot position and Rs.10 on the futures position Return the Borrow funds.Finally if the cost of borrowing funds to buy the security is less than thearbitrage profit possible, it makes sense for the investor to enter into thearbitrage. This is termed as cash – and- carry arbitrage. BUY FUTURES, SELL SPOT: In this the investor observing that futures have been underpriced, how can the investor cash in this opportunity to earn risk lessprofits. Say for i nst ance AC = 1000 and One month ACC futures = 965. CThis shows that futures have been under priced and therefore as anArbitrageur, investor can make r i sk l ess pr of i t s ent er i ng i nt o t hef ol l ow ng set f t r ansact i ons. i On day one, sell the security on the spot market at 1000 Mae delivery of the security Simultansely, buy the futures on the security at 965

On the futures expiration date, the spot and futures converge . Now unwind the position Sa y the security closes at Rs.975. Sell the security Futures position expires with the profit f Rs.10 The result is a risk less profit of Rs.25 the spot position and Rs.10 on the futures positionFinally if the returns get investing in risk less instruments is less thanthe return from the arbitrage it makes sense for the investor to enterinto the arbitrage. This is termed as reverse cash – and- carry arbitrage. ARBITRAGE WITH NIFTY FUTURES:Arbitrage is the opportunity of taking advantage of the price differencebetween two markets. An arbitrageur will buy at the cheaper market andsell at the costlier market. It is possible to arbitraged between NIFTY inthe futures market and the cash market. If the futures price is any of theprices given below other than the equilibrium price then the strategy tobe followed isCASE-1Spot Price of INFOSEYS = 1650Future Price Of INFOSEYS = 1675

In this case the arbitrageur will buy INFOSEYS in the cash market atRs.1650 and sell in the futures at Rs.1675 and finally earn risk free profitOf Rs.25.CASE-2Future Price Of ACC = 675Spot Price of ACC = 700In this case the arbitrageur will buy ACC in the Future market at Rs.675and sell in the Spot at Rs.700 and finally earn risk free profit Of Rs.25.INTRODUCTION TO OPTIONSIt is a interesting tool for small retail investors. An option is a contract,which gives the buyer (holder) the right, but not the obligation, to buy orsell specified quantity of the underlying assets, at a specific (strike) priceon or before a specified time (expiration date). The underlying may bephysical commodities like wheat/ rice/ cotton/ gold/ oil or financialinstruments like equity stocks/ stock index/ bonds etc.MONTHLY OPTIONS :The exchange trade option with one month maturity and the contractusually expires on last Thursday of every month.PROBLEMS WITH MONTHLY OPTIONSInvestors often face a problem when hedging using the three-monthlycycle options as thepremium paid for hedging is very high. Also the trader has to pay moremoney to take a long or short position which results into iiliquidity in themarket.Thus to overcome the problem the BSE introduced WEEKLYOPTIONSWEEKLY OPTIONS:The exchange trade option with one or weak maturity and the contractexpires on last Friday of every weakADVANTAGES Weekly Options are advantageous to many to investors, hedgers and traders.

The premium paid for buying options is also much lower as they have shorter time to maturity. The trader will also have to pay lesser money to take a long or short position. the trader can take a larger position in the market with limited loss. On account of low cost, the liquidity will improve, as more participants would come in. Weekly Options would lead to better price discovery and improvement in market depth, resulting in better price discovery and improvement in market efficiencyTYPES OF OPTION: CALL OPTIONA call option gives the holder (buyer/ one who is long call), the right tobuy specified quantity of the underlying asset at the strike price on orbefore expiration date. The seller (one who is short call) however, has theobligation to sell the underlying asset if the buyer of the call optiondecides to exercise his option to buy. To acquire this right the buyerpays a premium to the writer (seller) of the contract.ILLUSTRATIONSuppose in this option there are two parties one is Mahesh (call buyer)who is bullish in the market and other is Rakesh (call seller) who isbearish in the market.The current market price of RELIANCE COMPANY is Rs.600 and premiumis Rs.25 1. CALL BUYERHere the Mahesh has purchase the call option with a strike price ofRs.600.The option will be excerised once the price went above 600. Thepremium paid by the buyer is Rs.25.The buyer will earn profit once theshare price crossed to Rs.625(strike price + premium). Suppose the stockhas crossed Rs.660 the option will be exercised the buyer will purchasethe RELIANCE scrip from the seller at Rs.600 and sell in the market atRs.660. Profit 30

SHORT POSITIONIf the investor expects price to fall i.e. bearish in the market he takes ashort position by selling call option. PUT OPTIONA Put option gives the holder (buyer/ one who is long Put), the right tosell specified quantity of the underlying asset at the strike price on orbefore a expiry date. The seller of the put option (one who is short Put)however, has the obligation to buy the underlying asset at the strike priceif the buyer decides to exercise his option to sell.ILLUSTRATIONSuppose in this option there are two parties one is Dinesh (put buyer)who is bearish in the market and other is Amit(put seller) who is bullishin the market.The current market price of TISCO COMPANY is Rs.800 and premium isRs.2 0 1) PUT BUYER(Dinesh):Here the Dinesh has purchase the put option with a strike price ofRs.800.The option will be excerised once the price went below 800.

price price.FACTORS AFFECTING OPTION PREMIUM THE PRICE OF THE UNDERLYING ASSET: (S)Changes in the underlying asset price can increase or decrease thepremium of an option. These price changes have opposite effects on callsand puts.For instance, as the price of the underlying asset rises, the premium of acall will increase and the premium of a put will decrease. A decrease inthe price of the underlying asset’s value will generally have the oppositeeffect Premium of thePremium of the Price of the CALL Price of CALL Underlying Underlying asset assetPremium of the Premium of thePUT PUT THE SRIKE PRICE: (K)The strike price determines whether or not an option has any intrinsicvalue. An option’s premium generally increases as the option gets furtherin the money, and decreases as the option becomes more deeply out ofthe money. Time until expiration: (t)An expiration approaches, the level of an option’s time value, for putsand calls, decreases.

Volatility:Volatility is simply a measure of risk (uncertainty), or variability of anoption’s underlying. Higher volatility estimates reflect greater expectedfluctuations (in either direction) in underlying price levels. Thisexpectation generally results in higher option premiums for puts andcalls alike, and is most noticeable with at- the- money options. Interest rate: (R1)This effect reflects the “COST OF CARRY” – the interest that might be paidfor margin, in case of an option seller or received from alternativeinvestments in the case of an option buyer for the premium paid.Higher the interest rate, higher is the premium of the option as the costof carry increases.PLAYERS IN THE OPTION MARKET: a) Developmental institutions b) Mutual Funds c) Domestic & Foreign Institutional Investors d) Brokers e) Retail Participants

FUTURES V/S OPTIONS RIGHT OR OBLIGATION : Futures are agreements/contracts to buy or sell specified quantity of theunderlying assets at a price agreed upon by the buyer & seller, on orbefore a specified time. Both the buyer and seller are obligated tobuy/sell the underlying asset.In case of options the buyer enjoys the right & not the obligation, to buyor sell the underlying asset. RISKFutures Contracts have symmetric risk profile for both the buyer as wellas the seller.While options have asymmetric risk profile. In case of Options, for a buyer(or holder of the option), the downside is limited to the premium (optionprice) he has paid while the profits may be unlimited. For a seller orwriter of an option, however, the downside is unlimited while profits arelimited to the premium he has received from the buyer. PRICES:The Futures contracts prices are affected mainly by the prices of theunderlying asset.While the prices of options are however, affected by prices of theunderlying asset, time remaining for expiry of the contract & volatility ofthe underlying asset. COST:It costs nothing to enter into a futures contract whereas there is a cost ofentering into an options contract, termed as Premium.

STRIKE PRICE:In the Futures contract the strike price moves while in the optioncontract the strike price remains constant . Liquidity:As Futures contract are more popular as compared to options. Also thepremium charged is high in the options. So there is a limited Liquidity inthe options as compared to Futures. There is no dedicated trading andinvestors in the options contract. Price behaviour:The trading in future contract is one-dimensional as the price of futuredepends upon the price of the underlying only. While trading in option istwo-dimensional as the price of the option depends upon the price andvolatility of the underlying. PAY OFF:As options contract are less active as compared to futures which resultsinto non linear pay off. While futures are more active has linear pay off .

OPTION STRATAGIES: 1. BULL CALL SPREAD:This strategy is used when investor is bullish in the market but to alimited upside .The Bull Call Spread consists of the purchase of a lowerstrike price call an sale of a higher strike price call, of the same month.However, the total investment is usually far less than that required topurchase the stock.Current price of PATNI COMPUTERS is Rs. 1500Here the investor buys one month call of 1490 at 25 ticks per contractand sell one month call of 1510 and receive 15 ticks per contract.Premium = 10 ticks per contract(25 paid- 15 received)Lot size = 600 sharesBREAK- EVEN- POINT= 1490+10=1500Possible outcomes at expiration: i.

OPTION PAYOFF Profit Loss5). STRADDLE:In this strategy the investor purchase and sell the call as well as the putoption of the same strike price, the same expiration date, and the sameunderlying. In this strategy the investor is neutral in the market.This strategy is often used by the SPECULATORS who believe that assetprices will move in one direction or other significantly or will remain fairlyconstant.TYPES:LONG STRADDLE:Here the investor takes a long position(buy) on the call and put with thesame strike price and same expiration date. In this the investor isbeneficial if the price of the underlying stock move substantially in eitherdirection. If prices fall the put option will be profitable an if the prices

rises the call option will give gains. Profit potential in this strategy isunlimited ,While the loss is limited up to the premium paid. This willoccur if the spot price at expiration is same as the strike price of theoptions.SHORT STRADDLE:This strategy is reverse of long straddle. Here the investor write(sell) thecall as well as the put in equal number for the same strike price an sameexpiration. This strategy is normally used when the prices of theunderlying stock is stable but the investor start suffering losses if themarket substantially moves in either direction .Detailed example of a long straddleCurrent market price of BAJAJ AUTO is Rs.600Here the investor buys one month call of strike price 600 at 20 ticks percontract and two month put of strike price 600 for 15 ticks per contract.Premium Paid = 35 ticksLot size = 400 sharesLower Break- Even- Point = 600 – 35 = 565Higher Break- Even- Point = 600 + 35 = 635 i.

Here the investor purchases a higher call and a lower put withdifferent strike price and with the different expiration date. A longstrangle strategy is used to profit from a volatile price an loss from stableprices. 2)SHORT STRANGLE:In this the investor sells a higher call and a lower put with different strikeprice and with the different expiration date. A short strangle strategy isused to profit from a stable prices an loss starts when price is volatile.Detailed example of a short strangleCurrent market price of BSE INDEX is Rs.4000Here the investor sells a two month call of strike price 4050 for 20 ticksper contract and two month put of strike price 3950 for 15 ticks percontract.Premium Received = 35 ticksLot size = 300 sharesLower Break- Even- Point = 3950 – 35 = 3915Higher Break- Even- Point = 4050 + 35 = 4085On Expiration: i.

7) COVERED CALL: Under this strategy investors buys the shares which shows that theyare bullish in the market but suddenly they are scared about the marketfalls thus they sells the call option. Here the seller is usually negative orneutral on the direction of the underlying security. This strategy is bestimplemented in a bullish to neutral market where a slow rise in themarket price of the underlying stock is anticipated. Thus if price rises he will not participate in the rally. However he hasnow reduced loss by the amount of premium received, if pricesfalls.Finally if prices remains unchanged obtains the maximum profitpotential.EXAMPLE:Portfolio: 100 shares purchased at Rs.300Components: Sell a two month Reliance call of 300 strike at 25Net premium: 25 ticksPremium received: Rs.2500 (25*100, the multiplier)Break-even-point: Rs.275:Rs.300-25 (Premium received)Possible outcomes at expiration:If the stock closes at 300, the 300 call option will not exercised and sellerwill receive the premium.If the stock ends at 275, the 300 call option expires worthless equilant tothe premium received results into no profit no loss.If the stock ends above 300, the 300 call option is exercised and callwriter receives the premium results into the maximum profit potential.The payoff diagram of a covered call with long stock + short call = shortput Profit: Break- Even- 50 25 0 250 275 300 325 350 -25

-50 Loss8) COVERED PUT: Here the writer sell stock as well as put because he overall moderatebearish on the market and profit potential is limited to the premiumreceived plus the difference between the original share price of the shortposition and strike price of the put. The potential loss on this position,however is substantial if price increases above the original share price ofthe short position. In this case the short stock will suffer losses which willbe offset by the premium received. Profit: breakeven- Premium ReceivedLower Loss 9) UNCOVERED CALL:This strategy is reverse of the covered call. There is no opposite positionin the naked call. A call option writer (seller) is uncovered if the shares ofthe underlying security represented by the option is not owned by theoption writer.

The object of an uncovered call writer is to realize income by writing(selling) option without committing capital to the ownership of theunderlying shares.This shows that the seller has one sided position in the contract for thisthe seller must deposit and maintain sufficient margin with the broker toassure that the stock can be purchased for delivery if option is exercised.RISKS INVOLVED IN WRITING UNCOVERED CALL OPTION ARE ASFOLLOWS:- If the market price of the stock rises sharply the calls could be exercised, while as far as the obligation is concerned the seller must buy the stock more than the option strike price, which results in a substantial loss. The rise of buying uncovered calls is similar to that of selling stock although, as an option writer, the risk is cushioned somewhat by the amount of premium received. ILLUSTRATION: Portfolio: Write reliance call of 65 strike Net premium: 6 Lot size: 100 shares Market action: price settled at 55 Therefore the option will not be assigned because the seller has no stock position and price decline has no effect on the profit of the premium received. Suppose the price settled at Rs.75 the option assigned and the seller has to cover the position at a net loss of Rs.400 [1000 (loss on covering call)- 600(premium income)] Finally the loss is unlimited to the increase in the stock price and profit is limited to the declining stable stock price.10) PROTECTIVE PUT: Under this strategy the investor purchases the stock along with the put option because the investor is bearish in the market. This strategy

enables the holder of the stock to gain protection from a surprise decline in the price as well as protect unrealized profits. Till the option expires, no matter what the price of underlying is, the option buyer will be able to sell the stock at strike price of put option. SCENARIO Price of HLL: 200 Components: Buy a one-month put of strike 200 Net premium: 10 ticks per contract Premium paid: 1000 (10*100 multiplier) Break-even-point: 210 (Rs.200+10, Premium paid) Here the investor pays an additional margin of Rs.10 along with the price of Rs.210 combining a share with a put option is referred as a Protective Put. Possible outcomes at expiration AT BREAK-EVEN-POINT:Previously if the price rises to 200 the investor will gain but now theinvestor pays an margin of Rs.10. If price rises to Rs.210 then only theinvestor will gain. BELOW STRIKE PRICE:In case of fall in the stock price the loss is limited to Rs.18. This meansthat he maximum loss that the investor would have to bear is limited tothe extent of premium paid.If the price falls at 190 the investor will sell at 200. ABOVE STRIKE PRICE :In case of rise in prices then the put option will expire worthless and theinvestor will benefit from rise in the stock price.Finally uncertainty is the biggest curse of the market and a protective puthelps override the uncertainty in the markets. Protective put removes theuncertainty by limiting the investor loss at Rs.10. In this case no matterwhat happens to the investor is protected by the loss of Rs.10. The putoption makes the investor life by telling the investor in advance howmuch it stands to loss. This is also referred to as PORTFOLIO INSURANCE

because it helps the investor by insuring the value of investment just likeany other asset for which the investor would purchase insurance. profit: 20 Break- Even- 10 0 180 190 200 210 220 -10 -20 Loss PRICING OF AN OPTION DELTA A measure of change in the premium of an option corresponding to a change in the price of the underlying asset. Change in option premium Delta = -------------------------------- Change in underlying price FACTORS AFFECTING DELTA OPTION: Strike price Risk free interest rate Volatility Underlying price Time to maturity

ILUSTRATIONThe investor has buys the call option in the future contract for the strikeprice of Rs.19. The premium charged for the strike price of 19 at 0.80The delta for this option is 0.5.Here if the price of the option rises to20.A rise of 1. then the premium will increase by 0.5 x 1.00 = 0.50. The newoption premium will be 0.80 + 0.50 = Rs 1.30.Here in the money call option will increase the delta by 1.which will makethe value more and expensive while at the money option have the deltato 0.5 and finally out the money call option will have the delta very closeto 0 as the change in underlying price is not likely to make them valuableor cheap and reverse for the put optionDelta is positive for a bullish position (long call and short put) as thevalue of the position increases with rise in the price of the underlying.Delta is negative for a bearish position (short call and long put) as thevalue of the position decreases with rise in the price of the underlying.Delta varies from 0 to 1 for call options and from –1 to 0 for put options.Some people refer to delta as 0 to 100 numbers.ADVANTAGEThe delta is advantageous for the option buyer because it can tell himmuch of an option and accordingly buyer can expect his short termmovements by the underlying stock. This can help the option of an buyerwhich call/put option should be bought. GAMMAA measure of change in the delta that may occur corresponding to therise or fall in the price of the underlying asset.Gamma = change in option delta __________________ change in underlying price

The gamma of an option tells you how much the delta of an option wouldincrease or decrease for a unit change in the price of the underlying. Forexample, assume the gamma of an option is 0.04 and its delta is 0.5. Fora unit change in the price of the underlying, the delta of the option wouldchange to 0.5 + 0.04 = 0.54. The new delta of the option at changedunderlying price is 0.54; so the rate of change in the premium hasincreased. suppose the delta changed to 0.5-0.04 = 0.46 thus the rate ofpremium will decreased .In simple terms if delta is velocity, then gamma is acceleration. Delta tellsyou how much the premium would change; gamma changes delta andtells you how much the next premium change would be for a unit pricechange in the price of the underlying.Gamma is positive for long positions (long call and long put) and negativefor short positions (short call and short put). Gamma does not mattermuch for options with long maturity. However for options with shortmaturity, gamma is high and the value of the options changes very fastwith swings in the underlying prices THETA:A measure of change in the value of an option corresponding to its timeto maturity. It is a measure of time decay (or time shrunk). Theta isgenerally used to gain an idea of how time decay is affecting yourportfolio. Change in an option premiumTheta = -------------------------------------- Change in time to expiryTheta is usually negative for an option as with a decrease in time, theoption value decreases. This is due to the fact that the uncertaintyelement in the price decreases.ILLUSTRATIONSuppose the theta of Infosys 30-day call option with a strike price ofRs3,900 is 4.5 when Infosys is quoting at Rs3,900, volatility is 50% andthe risk-free interest rate is 8%. This means that if the price of Infosysand the other parameters like volatility remain the same and one daypasses, the value of this option would reduce by Rs.4.5.ADVANTAGE

Theta is always positive for the seller of an option, as the value of theposition of the seller increases as the value of the option goes down withtime.DISADVANTAGETheta is always negative for the buyer of an option, as the value of theoption goesdown each day if his view is not realized.In simple words theta tells how much value the option would lose afterone day, with all the other parameters remaining the same. VEGAThe extent of extent of change that may occur in the option premium,given a change in the volatility of the underlying instrument.Change in an option premiumVega = ----------------------------------------- Change in volatilityILLUSTRATIONSuppose the Vega of an option is 0.6 and its premium is Rs15 when volatilityof theunderlying is 35%. As the volatility increases to 36%, the premium of theoptionwould change upward to Rs15.6.Vega is positive for a long position (long call and long put) and negative fora short position (short call and short put).ADVANTAGESimply put, for the buyer it is advantageous if the volatility increases after hehasbought the option.DISADVANTAGEFor the seller any increase in volatility is dangerous as the probability of hisoption getting in the money increases with any rise in volatility.

In simple words Vega indicates how much the option premium would changefor a unit change in annual volatility of the underlying.DERIVATIVES PRODUCTS OFFERED BY BSE SENSEX FUTURES A financial derivative product enabling the investor to buy or sell underlying sensex on a future date at a future price decided by the market forces First financial derivative product in India.

OPEN INTEREST(OPTIONS)Open Interest is a crucial measure of the derivatives market. The totalnumber of options contracts outstanding in the market at any given pointof time. In short Sum of all positions taken by different traders reflectsthe Open Interest in a contract. Opposite positions taken by a trader in acontract reduces the open interest. However, opposing positions taken (inthe same contract) by two different traders are added to the open interest.Assuming that the market consists of three traders only following tableindicates how Open Interest changes on different day’s trades in PATNICOMPUTERS with a call American option at a strike price of Rs. 180DAY TRADER 1 TRADER 2 TRADER 3 OPEN INTEREST1 LONG 1200 SHORT 2400 LONG 1200 48002 NO TRADE LONG 1200 SHORT 1200 24003 LONG 1200 NO TRADE SHORT 1200 24004 SHORT 2400 LONG 1200 LONG 1200 0OPEN INTEREST(FUTURES)The total number of net outstanding futures contracts is called as openinterest i.e. long minus short contracts. A decline in open interest of thenear term futures indicates a short-term weakness whereas an increasein the open interest in the long term futures indicate that the marketsmay bounce back after some time provided this trend persists for a longtimeA rising open interest in an uptrend is BullishA declining open interest in an uptrend is BearishA rising open interest in a downtrend is BearishA declining open interest in a downtrend is Bullish

“RELIANCE ADD 5LAKH SHARES IN THE OPEN INTEREST”This shows that total number of option contracts comprising of 5lakhshares are outstanding in the market. There has been no square offpositions(opposite positions) in the market. Thus from the openinterest we come to know long and short positions made by theinvestor.RELATIONSHIP OF OPEN INTEREST WITH MARKET VOLUMES If open interest and market volumes increases but the market is bullish this shows that there has been buying positions in the market, which results into the positive open interest. If open interest and volumes increases but the market is in the bearish phase this shows that there has been selling positions made by the investor which results into the negative open interest If open interest remains constant and volumes are increasing and market is also bullish this shows that there has been intra day trading in the market. RELATIONSHIP OF OPEN INTEREST WITH PRICES If both open interest and prices are increasing, this shows that the buyers have entered in the market unfolding. Expect the uptrend to continue. If on the other hand, open interest is increasing while prices decline, sellers are expecting for the price rise in a technically weak

market. As open interest is growing while prices decline, buyers are obviously the more aggressive party. In the event of open interest declining while prices are also slipping, liquidation by long positions is the implication, therefore suggesting a technically strong market overall. In other words, the market is strong as open interest declining suggests no new aggressive shorts, as this would entail an increase in open interest. When open interest is declining and prices are increasing, short covering is the most likely cause suggesting that overall the market is weak - i.e. attracting new buyers would be required for a technically strong market and consequently open interest would rise.ILLUSTRATIONSuppose there are only two brokers Mr. A and Mr. B in the market. A buysand B sells contracts on Index futures on a specific day. At the end of theday , we may say that open interest in the market is 10 contracts andvolume for the day is 10 contracts.Now, if next day a new trader Mr. C comes from Mr. A, open interest atthe endo f the 2 day of trading remains same 10 contracts and volumefor the day is again 10 contracts. Understand that on the second day, Mr.C assumes Mr. A’s position on first day of trading. But for the market as awhole, at the end of the 2nd day all only 10 contracts remain open.COST OF CARRYThe relationship between futures and spot prices can be summarized interms of what is know as the cost of carry. This measures the storagecost plus the interest that is paid to finance the asset less the incomeearned on the asset.Cost of carry gives us an idea about the demand-supply forces in thefutures market. It basically indicates the annualized interest cost whichplayers are willing to pay (receive) for buying (selling) a futures contract.In the Indian markets the cost of carry marketing varies between anegative 35% per annum to a positive 35 % per annum. It can even behigher or lower than the 35% figure but that would be an extraordinary

event. We all know that at expiry the futures price closes at the cash priceof the security or an index.The cost-of-carry model in financial futures, thus, isFutures price = Spot price + Carrying cost — Returns (dividends, etc.)RELATIONSHIP OF FUTURES PRICE WITH SPOT PRICE FUTURES PRICE HIGHER THAN THE CASH PRICE Here futures price exceeds the cash price which indicates thatthe cost of carry is negative and the market under such circumstances istermed as a backwardation market or inverted market.EXAMPLESuppose the RELIANCE share is trading at Rs.400 in the spot market.While RELIANCE FUTURES is trading at Rs.406.Thus in this circumstancesthe normal strategy followed by investors is buy the RELIANCE in the spotmarket and sell in the futures. On expiry, assuming RELIANCE closes at Rs450, you make Rs.50 by selling the RELIANCE stock and lose Rs.44 bybuying back the futures, which is Rs 6 in a month. Thus Futures pricesare generally higher than the cash prices, in an overbought market. CASH PRICE HIGHER THAN THE FUTURES PRICEHere cash price exceeds the futures price which indicates that the cost ofcarry is positive and this market is termed as oversold market. This maybe due to the fact that the market is cash settled and not delivery settled,so the futures price is more a reflection of sentiment, rather than that ofthe financing cost.EXAMPLENow let us assume that the RELIANCE share is trading at Rs.406 in thespot market. While RELIANCE FUTURES is trading at Rs.400.Thus in this

circumstances the normal strategy followed by investors is buy theRELIANCE FUTURES and sell the RELIANCE in the spot market. So atexpiry if Reliance closes at Rs 450, the investor will buy back the stock ata loss of Rs 44 and make Rs 50 on the settlement of the futures position.This is applied when the cost of carry is high.Thus t he ar bi t r ageur can appl y t hi s st r at egy and make t he pr of i t s

VOLATILITYVolatility is one of the most important factors in an option’s price. Itmeasures the amount by which an underlying asset is expected tofluctuate in an given period time. It significantly impacts the price of anoption’s premium and heavily contributes to an option’s time value.In basic terms, volatility is merely a term used to describe how fast astock, future or index changes with respect to change in the price. It canbe viewed as the speed of change in the market, although the investormay prefer to think of it is as market confusion. The more confused amarket is the better the chance an option of ending up “in the money”. Astable market moves slowly. Volatility measures the speed of change inthe price of the underlying instrument or the option. Higher the volatilitythe more the chance an option of becoming profitable by expirationRELATIONSHIP OF PRICE VOLATILITY WITH PREMIUMHigher the price volatility of the underlying stock of the put option,higher would be the premium.Lower the price volatility of the underlying stock of the call option, lowerwould be the premium.TYPES OF VOLATILITY HISTORICAL VOLATILITY: This (also called statistical volatility) measures price movement interms of past. Historical volatility is calculated by using thestandard deviation of underlying asset price changes from close to closeof trading for a given period - month, half yearly, annualized IMPLIED VOLATILITY: It is the option market predication of volatility of the underlying instrument over the life of the option. It helps in determining what strategies are to be used.When implied volatility is high, the market price of the option will be greater than their theoretical price.

ExampleStock Price: Rs 280Strike Price: Rs 260Annual volatility: 50%Days to expiry 20 daysInterest rate 12% annualThe price of the Option applying Black-Scholes Model comes to Rs 26.28.But the actual price of that Option in the market might be (say) Rs 29.50.This means that the market is imputing another volatility to that optiongoing forward. Now instead of providing the volatility figure yourself, youcan provide the Option price instead. Now if the investor work backwardsand find out what is the volatility that would support the price of Rs29.50, that volatility comes to 65 per cent.While the value of a call option is an increasing function of the value of itsunderlying, it is also an increasing function of the volatility of itsunderlying. That is, the more uncertain the underlying, the more theoption is worth.From the above scenario it is possible that the players are expecting thescrip to increase another possibility is that the market is mis-pricing theoption and could fall. It could also be possible that the market isanticipating some development, which could push the stock higher. If youbelieve that volatility would rise and the underlying then you may go infor a bull strategy or if you are an aggressive player you could sell theoption with a belief to buy them at a later date.Most traders, however, use a general rule of thumb: Buy options in lowvolatility and sell options during periods of high volatility.If you see low implied volatilities, you should buy the At the Money (ATM)option and sell an Out of the Money (OTM) option. You can also create asimilar position using puts. In this case, you should buy ATM and sell Inthe Money (ITM) put options. If you see high implied volatilities, youshould buy an In the Money (ITM) Call and sell an ATM call. You will findthat both the calls are expensive, but the ATM will be in mostcircumstances more expensive than the others. Thus, by selling the ATMcall, you can realize a good price.

Finally implied volatility can increase or decrease even without pricechanges ion the underlying security. This is because implied volatility isthe level of expected volatility i.e. it is also based not on actual prices ofthe security, but expected price trends. Implied voltility also declines, asthe option gets closer to expiration, as changes in volatility become lesssignificant with fewer trading daysBEST STRATEGY TO BE FOLLOWED IN CASE OF IMPLIED VOLATILITYSHORT STRADDLE:These involve simultaneously selling put and call options for the samestock, same strike price and with the same expiration date. In contrast, ashort strangle involves simultaneously selling both a put and call on thesame stock and same expiration date, but with the different strike price.ILLUSTRATIONLets choose the strike price 165 in Satyam for the June contracts. Satyamis one of the most actively traded contracts in the NSE F&O segment.The IV for the call is 97.66 per cent and that of put is 99.40 per cent onApril 25, 2005 Since the IV is high, it is a premium-selling time. (a goodtime to sell calls and puts)# On May 25, the investor `short straddle the Satyam by selling the 165call and put for Rs 27.# The inflow in this strategy is Rs 54 (2X27).# The underlying spot has been trading within a range of 157-177.# However, the call IV has ranged from 99.40 - 63.36 and that of put hasranged from 97.66-46.01# On May 29, 2003 the IV of call and put are low, hence the investor cansquare off positions.# The respective IV was 63.36 for call and 46.01 for put. The underlyingSatyam was Rs 169.50.

# The call closed at Rs 11.45 and the put closed at Rs 9.50.# Square-off position by buying call and put of the same strike. Youroutflow would be 20.95 (11.45+9.50). Hence, your net profits would beRs 33.05 (54-20.95).Here the strategy has “limited profit and unlimited losses”. Here the Profitis limited to the premiums received. Losses would be unlimited if you arewrong on the stock outlook and the volatility outlook.
