Weighted average returns of a portfolio:

Weighted average returns on a portfolio can be calculated as sum of products of Weights and return of each individual asset present in the portfolio. The portfolio weights can also be calculated using the same formula if the portfolio returns are provided.

Answer and Explanation: 1

The basic formula for expected return from portfolio is:

{eq}Return =\sum_{w_{i}*r}^{i} {/eq}

Here 'w' is the weight on individual asset and 'r' is the return.

For two asset the formula can be shortened to:

{eq}Return= (w_{X}*r_{X})+(w_{Y}*r_{Y}) {/eq}

Here we have:




Now wX+wY=1, since these are the only assets present.


Hence we substitute wX with 1-wY in the equation.



wY=0.43 or 43%

wX=1-0.43=0.57 or 57%

Hence the amounts invested are:
