What is the sharpe ratio (reward-to-variability) of the cal line that joins the risk-free asset and optimal risky asset p?

Answer 1

In finance, the Sharpe ratio (also known as the Sharpe index, Sharpe measure, or reward-to-volatility ratio) measures the performance of an investment, such as a security or portfolio, compared to a risk-adjusted, risk-free asset. It is defined as the difference between the investment return and the risk-free return divided by the standard deviation of the investment return. It represents the additional return an investor receives for each unit of increased risk.

A Sharpe ratio of 1 is considered good, 2 is considered excellent, and 3 is considered very good. As a guideline, a ratio of 1 or higher is considered good, 2 or higher is very good, and 3 or higher is excellent.
