  14. 14. • Graph of S&P CNX Nifty from January 1997 to March 2011• The S&P CNX Nifty covers 22 sectors of the Indian economyand offers investment managers exposure to the Indian market in one portfolio. The S&P CNX Nifty stocks represents about 67.27% of the free float market capitalization of the stocks listed at  National Stock Exchange (NSE) as on September 30, 2012.• The S&P CNX Nifty index is a free float market capitalisation weighted index. The index was initially calculated on full market capitalisation methodology. From June 26, 2009, the computation was changed to free float methodology. The base period for the S&P CNX Nifty index is November 3, 1995, which marked the completion of one year of operations of NSEs Capital Market Segment. The base value of the index has been set at 1000, and a base capital of Rs 2.06 trillion. [1] The S&P CNX Nifty Index was developed by Ajay Shah and Susan Thomas.
  15. 15. Currency of Calculation• For the S&P CNX Nifty, all prices are in Indian rupees.Base Date• The base period for the S&P CNX Nifty index is November 3, 1995, which marked the completion of one year of operations of NSEs Capital Market Segment. The base value of the index has been set at 1000, and a base capital of Rs 2.06 trillion.
  16. 16. Partnership• The S&P CNX Nifty is owned and managed by India Index Services and Products Ltd. (IISL), which is a joint venture between the NSE and CRISIL. IISL is India’s first specialized company focused on an index as a core product. IISL has a licensing and marketing agreement with Standard & Poor’s, who is a world leader in index services.
  17. 17. Highlights• The S&P CNX Nifty is a 50 stock, float-adjusted market- capitalization weighted index for India, accounting for 21 diversified sectors of the economy. It is used for a variety of purposes, such as benchmarking fund portfolios, index based derivatives and index funds.• The S&P CNX Nifty is derived from economic research and is created for those interested in investing and trading in Indian equities.
  18. 18. Market Representation. & Diversification.Market Representation.• The S&P CNX Nifty stocks represent about 65% of the total float- adjusted market capitalization of the National Stock Exchange (NSE).Diversification.• The S&P CNX Nifty is a diversified index, accurately reflecting the overall market. The reward-to-risk ratio of S&P CNX Nifty is higher than other leading indices, offering similar returns but at lesser risk.
  19. 19. Liquidity.• Market impact cost is the best measure of the liquidity of a stock. It accurately reflects the costs faced when actually trading an index. For a stock to qualify for inclusion in the S&P CNX Nifty, it has to reliably have market impact cost below 0.50 %, when doing S&P CNX Nifty trades of Rupees (Rs) 20 million. The current impact cost of the S&P CNX Nifty for a portfolio size of Rs 20 million is 0.13%.
  20. 20. Hedging Effectiveness.• The basic risk of the S&P CNX Nifty futures is lower than other index portfolios, due to the liquidity of the S&P CNX Nifty constituent stocks and of the NSE. In addition, the S&P CNX Nifty has higher correlations with typical investment portfolios in India, compared to other indices. These two factors allow for effective hedging of the Index.
  21. 21. Index FamilyS&P CNX Defty.• The S&P CNX Defty is a U.S. dollar-denominated index based on the S&P CNX Nifty. This index was developed to provide a benchmark of Indian stocks to international investors, providing them with an instrument for measuring returns on their equity investment in dollar terms. This ensures that the risk arising out of currency fluctuation is covered through the S&P CNX Defty.

  23. 23. HOW ARE INDICES OF SENSEX AND NIFTYCALCULATED???
  24. 24. How are the SENSEX 30 & NIFTY 50 Stocks are selected?• Listing History• Trading Frequency• Rank based on the Market Cap (Should be Among top 100)• Market Capitalization weight• Industry / sector they belong• Historical Record
  25. 25. Free Float Market Capitalization?? The value of all the shares available forpublic trading excluding the promoterequity, holdings through FDI Route,Holdings by private corporate, andholdings by Employee Welfare Funds.
  26. 26. Why Free Flow Market Cap?1. It depicts the market more rationally2. It removes undue influence of government or promoter share holding, there by giving the equal opportunity for companies to be in the NIFTY3. Almost all the Indices world over are calculated by this methodology4. It gives Fund managers more authentic information for benchmark comparisons.
  27. 27. SENSEX & NIFTY CALCULATION METHODOLOGY
  28. 28. • SENSEX is calculated using the "Free-float Market Capitalization" methodology, wherein, the level of index at any point of time reflects the free-float market• It reflects value of 30 component stocks relative to a base period.• The market capitalization of a company is determined by multiplying the price of its stock by the number of shares issued by the company.• This market capitalization is further multiplied by the free-float factor to determine the free-float market capitalization.
  29. 29. • The base period of SENSEX is 1978-79 and the base value is 100 index points. ( notation 1978-79=100).• The calculation of SENSEX involves dividing the free-float market capitalization of 30 companies in the Index by a number called the Index Divisor.• The Divisor is the only link to the original base period value of the SENSEX. It keeps the Index comparable over time and is the adjustment point for all Index adjustments arising out of corporate actions, replacement of scrip’s etc.• During market hours, prices of the index scrips, at which latest trades are executed, are used by the trading system to calculate SENSEX every 15 seconds. The value of SENSEX is disseminated in real time.
  30. 30. How SENSEX is calculated?The formula for calculating the SENSEX = (Sum of free flowmarket cap of 30 benchmark stocks)*Index Factorwhere,Index Factor = 100/Market Cap Value in 1978-79. 100 is the Index value during 1978-79.
  31. 31. Example:Assume SENSEX has only 2 stocks namely SBI and RELIANCE.Total shares in SBI are 500 out of which 200 are held byGovernment and only 300 are available for public trading.RELIANCE has 1000 shares out of which 500 are held bypromoters and 500 are available for trading. Assume price ofSBI Stock is Rs.100 and Reliance is Rs.200. Then "free-FloatingMarket Cap" of these 2 companies =
  32. 32. (300*100+500*200) = 30000+100000 = Rs. 130000Assume Market Cap during the year 1978-79 was Rs.25000Then SENSEX = 130000*100/25000 = 520.The methodology in the example is exactly followed to calculatethe SENSEX, only difference being the inclusion of 30 stocks.
  33. 33. Calculations of the S&P CNX Defty• The U.S. dollar/Rupee exchange rate is based on a real-time polled indicative data feed, which contains bid/ask rates at a point in time. The polled data is sourced from Thomson Reuters. The data is polled from market participants, including leading nationalized banks, private Indian banks and foreign exchange brokers. The frequency of polled data is more than 3-4 updates per minute, depending on market volatility, totaling more than 1000 updates in a day. The closing value of S&P CNX Defty is computed based on a simple average of the U.S. dollar/Rupee exchange rates received during the last half an hour of trading on the National Stock Exchange of India Ltd. (NSE) and applied to the closing value of the S&P CNX Nifty.
  34. 34. Index Closure Algorithm• The closing SENSEX & NIFTY on any trading day is computed taking the weighted average of all the trades on SENSEX & NIFTY constituents in the last 30 minutes of trading session.• If a SENSEX & NIFTY constituent has not traded in the last 30 minutes, the last traded price is taken for computation of the Index closure.• If a SENSEX & NIFTY constituent has not traded at all in a day, then its last days closing price is taken for computation of Index closure.• The use of Index Closure Algorithm prevents any intentional manipulation of the closing index value.•
  35. 35. NIFTY The National Stock Exchange (NSE) is associated with NIFTY andit is also calculated by the same methodology but with two keydifferences.1. Base year is 1995 and base value is 1000.2. NIFTY is calculated based on 50 stocks.Everything else remains the same in NIFTY Index calculation aswell.
  36. 36. Benefits of Stock Exchanges to Community1. It assist the economies development by providing a body of interested investors.2. It uploads the position of superior enterprises and assist them in raising further funds.3. It encourages capital formation4. Government can undertake projects of national importance and social value raising funds through the sale of its securities on the stock exchange.5. It is the stock exchanges that central bank of a country can control credit by undertaking open market operations (purchase and sale of securities)
  37. 37. Benefits to Investor1. Liquidity of the investment is increased2. The securities dealt on a stock exchange are good collateral security for loans.3. The stock exchange safeguards interests of investors through strict enforcement of rules and regulations.4. The present net worth of investments can be easily known by the daily quotations.5. The risk is considerably less when investor holds or purchases listed securities.
  38. 38. Benefits to the company1. A company whose shares quoted on stock exchange they enjoy better reputation and credit.2. The market for the shares of such a company is naturally widened.3. The market price of securities is likely to be higher in relation to its earnings, dividends and property values. This raises the bargaining power of the company in the event of a takeover, merger or amalgamation.
  39. 39. ADJUSTMENTS FOR BONUS, RIGHTS ANDNEWLY ISSUED CAPITAL
  40. 40. Adjustment for Bonus, Rights and Newly Issued Capital• NIFTY calculation needs to be adjusted for issue of Bonus or Rights shares, If no adjustments are made, a discontinuity would arise between the current value of the index and its previous value despite the non-occurrence of any economic activity of substance• At the NSE Index Cell , the base value is adjusted, which is used to alter market capitalization of the component stocks to arrive at the NIFTY value.
  41. 41. Adjustments for Rights Issues• When a company, included in the compilation of the index, issues right shares, the free-float market capitalization of that company is increased by the number of additional shares issued based on the theoretical price.• An offsetting or proportionate adjustment is then made to the Base Market capitalization (see Base Market capitalization Adjustment below).
  42. 42. Adjustments for Bonus Issue• When a company, included in the compilation of the index, issues bonus shares, the market capitalization of that company does not undergo any change. Therefore, there is no change in the Base Market capitalization, only the number of shares in the formula is updated.Other Issues• Base Market capitalization adjustment is required when new shares are issued by way of conversion of debentures, mergers, spin-offs etc. or when equity is reduced by way of buy-back of shares, corporate restructuring etc.
  43. 43. Base Market capitalization Adjustment• The formula for adjusting the Base Market capitalization is as follows: New Market capitalization New Base Mkt. cap. = Old Base Mkt. cap. x ------------------------------- Old Market capitalization• To illustrate, suppose a company issues right shares which increases the market capitalization of the shares of that company by say, Rs.100 crores. The existing Base Market capitalization (Old Base Market capitalization), say, is Rs.2450 crores and the aggregate market capitalization of all the shares included in the index before the right issue is made is, say Rs.4781 crore
  44. 44. • 2450 x (4781+100) -------------------------- =Rs.2501.24crores         4781• This figure of Rs. 2501.24 crore will be used as the Base Market capitalization for calculating the index number from then onwards till the next base change becomes necessary.
