This document discusses different types of formula plans for portfolio management. It introduces constant ratio plans, variable ratio plans, and constant rupee value plans. Constant ratio plans maintain a fixed ratio between aggressive and defensive portfolios. Variable ratio plans adjust the ratio based on market price fluctuations. Constant rupee value plans force selling when prices rise and buying when they fall to maintain a constant rupee value of the aggressive portfolio. Formula plans provide rules for buying and selling securities and help investors make better use of market fluctuations.

3. Meaning of Formula Plans
• Formula plans are certain predefined
rules and regulations deciding when
and how much assets an individual
can purchase or sell for portfolio
revision.
• Securities can be purchased and
sold only when there are changes or
fluctuations in the financial market.
4. Why Formula plans ?
• Formula plans help an investor to make the best
possible use of fluctuation in the financial
market. One can purchase shares when prices
are less and sell off when market prices are
higher.
• With the help of formula plans an investor can
divide his funds into aggressive and defensive
portfolio and easily transfer funds from one
portfolio to other.
5. Aggressive Portfolio
• Aggressive Portfolio consists of funds
that appreciate quickly and guarantee
maximum returns to the investors.
6. • Defensive portfolio consists of
securities that do not fluctuate much
and remain constant over a period of
time.
Defensive portfolio
7. Advantages of the Formula Plans
• Basic rules and regulations for the purchase
and sale of securities are provided.
• The investors can earn higher profits by
adopting the plans.
• It helps to control the buying and selling of
securities by the investors.
• It is useful for taking decisions on the timing
of investment.
8. Types of formula Plans
• The Constant Rupee Value Plan
• The Constant Ratio Plan
• The Variable Ratio Plan
9. Constant rupee value plan
• This plan forces the investor to sell when the
prices rises and purchases as the price falls.
• In this plan, the rupee value of the aggressive
portfolio is held constant. Whenever the value of
the aggressive portfolio rises, a part of it is sold
to bring it back to its original value, and the funds
generated are re-invested in the defensive
portfolio.

13. CONSTANT RATIO PLAN
An investment strategy in which the market value of stocks and
bonds are kept at a predetermined ratio. That is, when compiling a
portfolio, an investor may decide that 60% of its value will consist of
bonds and 40% will be stocks. When prices rise or fall on the
securities in the portfolio, the investor will buy and sell accordingly in
order to maintain the ratio.
A constant ratio plan is a form which is done in order to reduce the
risk in the portfolio.
14. Constant Ratio Plan
Constant ratio between the aggressive and
conservative portfolios is maintained.
The ratio is fixed by the investor.
The investor’s attitude towards risk and
return plays a major role in fixing the ratio.
15. Initial Portfolio Value = Rs.20,000
Speculative Portion = 40%
Conservative Portion = 60%
Desired Speculative to Conservative Ratio =
0.67
Trigger Points: Maximum ratio = 1.33 or above,
Minimum ratio = 0.33 or below

17. Notes
Let the amount be Rs.x
We need to satisfy the following and solve for x:
(16000-x)/(12000+x) = 0.67
Therefore, x = Rs.4766.46
New Amount in the Speculation Portion = 16000 – 4766.46 = Rs.11233.54
New Amount in the Conservative portion = 12000 + 4766.46 = Rs.16766.46
Securities sold from Speculative Portion = 4766.46/20 = 238.32
New Securities in the Speculative Portion = 561.68
Let the amount be Rs.y
We need to satisfy the following and solve for :
(3931.76+y)/(16766.46-y) = 0.67
Therefore, y = Rs.4372.316
New Amount in the Speculation Portion = 3931.76 + 4372.31 = Rs.8304.07
New Amount in the Conservative portion = 16766.46 – 4372.31 = Rs.12394.15
Securities purchase = 4372.31/7 = 624.61
New Securities in the Speculative Portion = 1186.29
18. VARIABLE RATIO PLAN
Instead of maintaining a constant rupee amount in stocks or a
constant ratio of stocks to bonds, the variable ratio plan user steadily
lowers the aggressive portion of the total portfolio as stock prices
rise, and steadily increase the aggressive portion as stock prices
fall.
By changing the proportions of defensive aggressive holdings, the
investor is in effect buying stock more aggressively as stock prices
fall and selling stock more aggressively as stock prices rise.
19. Variable Ratio Plan
At varying levels of market price, the
proportions of the stocks and bonds change.
Whenever the price of the stock increases,
the stocks are sold and new ratio is adopted
by increasing the proportion of defensive or
conservative portfolio.
To adopt this plan, the investor is required to
estimate a long term trend in the price of the
stocks.
20. Initial Portfolio Value = Rs.20,000
Initial Speculative to Total ratio = 0.4 {Ratio 2:3}
Trigger Points: If the actual ratio goes to 0.6
and above, bring the speculative portion to 0.5
{1:1} and if the actual ratio goes to 0.2 or below,
raise the Speculative portion to 0.3

22. Notes
Desire Speculative Portion = 0.5 of total = Rs.16000
New Amount in the Speculation Portion = 20000 – 4000 = Rs.16000
New Amount in the Conservative portion = 12000 + 4000 = Rs.16000
Securities sold from Speculative Portion = 4000/25 = 160
New Securities in the Speculative Portion = 640
Desire Speculative Portion = 0.3 of total = Rs.5760
New Amount in the Speculation Portion = 3200 + 2560 = Rs.5760
New Amount in the Conservative portion = 16000 – 2560 = Rs.13440
Securities purchase = 2560/5 = 512
New Securities in the Speculative Portion = 1152
23. The Formula Plans
The formula plans provide the basic rules and
regulations for the purchase and sale of
securities.
The aggressive portfolio consists more of
common stocks which yield high return with
high risk.
The conservative/defensive portfolio consists
of more bonds that have fixed rate of returns.
24. Disadvantages of the
Formula Plan
The formula plan does not help the selection
of the security.
Should be applied for long periods, otherwise
the transaction cost may be high.
Investor needs forecasting.
