Problem $7-10$ three stocks with respect to each of these potential risk factors: FACTOR LOADING a$.$ Calculate expected returns for the three stocks using just the MKT risk factor. Assume a risk$-$free rate of $\backslash (5\mathrm{.}1\backslash \%\backslash ).$ Round your answers to three decimal places. Expected return for stock QRS: $\backslash \%$ Expected return for stock TUV: $\backslash \%$ Expected return for stock WXY: $\backslash \%$ b$.$ Calculate the expected returns for the three stocks using all three risk factors and the same $\backslash (5\mathrm{.}1\backslash \%\backslash )$ risk$-$free rate. Round your answers to three decimal places. Expected return for stock QRS: $\backslash \%$ Expected return for stock TUV: $\backslash \%$ Expected return for stock WXY: $\backslash (\backslash \%\backslash )$ c$.$ What sort of exposure might MACRO$2$ represent? MACRO$2$ might represent $\backslash (\backslash$overline$\{-$S$\_\{$i$\}\}\backslash )$ factor.
