1)Make a few comments on the risk characteristics of stockA and portfolio (comparing size and percentage of systematic and unsystemaic risk) and the performance of stockA and the portfolio of stocks.

StockA: Systematic Risk =0.032. %Systematic =54% and %Unsystematic =46% Discrete return = 0.26%

Portfolio: Systematic Risk =0.025. %Systematic =68% and %Unsystematic =32% Discrete return = 0.08%.

2)Also what insights can be identified between analysing a stock and a portfolios performance just using weekly returns compared to analysing the stock and portfolio when you use a risk free asset to calculate the stock/porfolios excess returns and SCL?

StockA:Discrete return = 0.26% Variance = 0.0035,

StockA SCL: Alpha = -.003, beta =2.5

Porfolio :Discrete return = 0.08%. Variance =.00020

Portfolio SCL: Alpha =-0.0035. Beta=2
