Question $4$

MSFT has an expected return of $0\mathrm{.}34$ and

a standard deviation sigma of $0\mathrm{.}34$

WMT has an expected return $.$ of $0\mathrm{.}11$ and

a standard deviation sigma of $0\mathrm{.}14$

The correlation between MSFT and WMT is $0\mathrm{.}48$

Compute the standard deviation of the portfolio if you

invest a fraction $0\mathrm{.}41$ into MSFT and the rest into WMT$.$
