Consider the following simplified APT model:

$\backslash$table$[[$Factor$,$Expected Risk Premium $(\%)],[$Market$,6\mathrm{.}0],[$Interest rate,$-0\mathrm{.}8],[$Yield spread,$4\mathrm{.}6]]$

$\backslash$table$[[,,$Factor Risk Exposures,$],[$Stock$,$Market $($ Interest Rate $($ Yield Spread $(,,],[$P$,($:$b_1\},($:$b_2\},b_3)],[P^2,1\mathrm{.}2,-1\mathrm{.}2,-0\mathrm{.}4],[P^3,1\mathrm{.}2,0,0\mathrm{.}3],[,0\mathrm{.}3,2\mathrm{.}1,0\mathrm{.}4]]$

Calculate the expected return for each of the stocks shown in the table above. Assume $r_f=3\mathrm{.}4\%.$

Note: Do not round intermediate calculations. Enter your answers as a percent rounded to $2$ decimal places.

Answer is complete but not entirely correct.

$\backslash$table$[[$Expected return P$,11\mathrm{.}56ox,\%$
