Below is the link for data file. The spreadsheet contains daily returns on 2 different stocks and the S&P/ASX200. The S&P/ASX200 is a proxy for the market portfolio. The daily returns are total returns and incorporate price changes and dividend payments. As the annual risk-free rate is very close to zero and you are using daily data, we can assume that the daily risk-free rate is zero.

3) Your discussion of the above points needs to incorporate relevant qualitative information on the two stocks from your own research.
