Let's say the stock return of Microsoft is 3.75% this month. The correlation (p) between its return and market return is 0.15. The standard deviation (o) of its return is 0.3. The standard deviation of market return is 0.5. What is the value of beta coefficient (3) here? What does this beta coefficient mean? Now you compute the conjectured stock return of Microsoft. It is 1.75 %. Is this stock currently overvalued or undervalued in SML? (Hint: B=P, and SML is related to CAPM.)
