Question $3$

Ch$\mathrm{.}11$: Portfolio Standard Deviation

Consider the following information. Your portfolio is invested $40\%$ percent each in Apple and

$60\%$ percent in Tesla. What is the standard deviation of this portfolio?

Note: You will have a standard deviation question on the final exam, but a different one than

this as it will be for an individual stock over several years and not for a portfolio of stocks. For

a sample of stocks, you have to divide the sum of the squared deviations by $n-1$ to determine

variance as shown on slide $9$ of chapter $10.$

$22\mathrm{.}72\%$

$42\mathrm{.}31\%$

$15\mathrm{.}62\%$

$17\mathrm{.}81\%$

$20\mathrm{.}56\%$

$25\mathrm{.}93\%$

$4\mathrm{.}23\%$

$14\mathrm{.}50\%$
