CAPM ASSIGNMENT Manish Singla Roll No. 186 Section C
Single Index Model o
o
Relates returns on each security to the returns on a common index, such as the CNX Nifty or Sensex Stock Index Expressed by the following equation : Ri

i R M
ei
Divides return return into two components: components: a unique part, i a market-related part, part, i.Rm Beta measures sensitivity of stock to stock market movements.
CAPM Model The capital asset pricing model provides a formula that calculates the expected return on a security based on its level of risk. The formula for the capital asset pricing model is the risk free rate plus beta times the difference of the return on the market and the risk free rate.

CAPM Model The capital asset pricing model provides a formula that calculates the expected return on a security based on its level of risk. The formula for the capital asset pricing model is the risk free rate plus beta times the difference of the return on the market and the risk free rate.
Procedure : 1.) Weekly returns were taken for stocks stocks and S&P BSE 500 500 for the last 1 year from BSE BSE website. 2.) Ex ante Beta calculated for the 103-252 data rows using the returns on equity and market for 1-98 data rows. This was done using SLOPE function in excel. 3.) 364 day T-bils rate was used as the risk free rate . rate . Rf was obtained by dividing this rate by 52 weeks. 4.) Ri-Rf was calculated for the 51-100 data rows. Regression analysis was done using Y values as Ri- Rf and X values as the Beta Following regression was used:
Hypothesis Testing If CAPM holds in general, correlation of equity return with the market return (βi) (β i) alone could provide sufficient explanation t o the risk premium, such that αi should be zero. For this reason, a hypothesis testing is performed with null hypothesis α=0 at 5% significance level. H0: α = 0 H1: α ≠ 0
Objective: In these observations, we are trying to analyze whether the CAPM model holds true for the stocks listed on the Bombay Stock Exchange or not.

Observation and Inferences: From the regression analysis, we can see the value of intercept is 0.0008 and the p-value is 0.87 Since x variable p-value > 0.05 we cannot accept the null hypothesis that α = 0 Hence we understand that the value of alpha is statistically zero in the regression Ri-Rf =αi + βi (Rm-Rf) + ei Hence we can conclude that the CAPM model does not hold true in Indian Equity Market taking the example of Colgate Palmolive
