Hypothesis Testing and Stock Returns

1. Download data for last 1 year for the S&P500 and any 10 of its component stocks. Download data from an appropriate financial website such as Google Finance, Yahoo Finance, Quandl, CityFALCON, or another similar source. 

2. Calculate daily returns of the S&P500 index and the downloaded stocks over the period under study 

3. For each of the selected stocks and the index perform a Student’s T test, calculate the p-value and t-value and test the Null Hypothesis that the mean daily stock return is zero.

Analysis: 

1. For how many stocks was the null hypothesis accepted. 

2. Given that you drew the stocks randomly from the index constituents, is it possible to extrapolate the behavior of the index (in terms of the null hypothesis) from the average results obtained from analyzing the stocks?
