Annual and Average Returns for Stocks, Bonds, and T$-$Bals, $1950$ to $2017$

You have a porttolio with an asset allocation of $43$ percent stocks, $30$ percent long$-$term Treasury bonds, and $27$ percent

T$-$bills. Use these weights and the retums glven in the above table to compute the return of the portfollo in the year

$2010$ and each year since. Then compute the average annual return and standard deviation of the portfolio. $($Do not

round intermediate calculations. Round your answers to $2$ decimal places.$)$
