| If the standard deviation of the market’s returns is 5.8%, the standard deviation of a stock’s returns is 8.2%, and the covariance of the market’s returns with the stock’s returns is 0.003, what is the beta of the stock? 
 
 The formula for beta is: (Covstock,market)/(Varmarket), or (0.003)/(0.058)2 = 0.89.
