Calculate the expected return, Sharpe ratio and Jensen's alpha for these portfolios and interpret all the results 2. Let's now compute the ratio of excess returns of the above investments (as in the numerator of the Sharpe ratio) but instead of dividing over the the portfolios' risk, divide by their betas This measure is called the Treynor ratio. In particular interpret the numbers that you find How are these numbers differ ent from those from the Sharpe ratios? hint: think of what is capturing versus what a portfolio's risk (or more generally an investment's risk) is capturing
