At the beginning of the year, you invested $8,000 in four stocks, but the investment in each stock was not equal. The amount split up in your portfolio is shown below:

Stock	Amount invested
Stock A	$1,000
Stock B	$2,000
Stock C	$1,000
Stock D	$4,000

1. Calculate the weight of each stock in the portfolio (the percentage invested in each stock).

Weight of Stock A	=	0.125 OR. 0.25 OR 0.75 OR 0.625 OR 0.5 OR 0.875 OR 0.375
Weight of Stock B	=	0.125 OR 0.625 OR 0.375 OR OR 0.75 OR 0.875 OR 0.5 0.25
Weight of Stock C	=	0.125 OR 0.25 OR 0.75 OR 0.625 OR 0.5 OR 0.875 OR 0.375
Weight of Stock D	=	0.75 OR 0.625 OR 0.25 OR 0.327 OR 0.875 OR 0.125

Now at the end of the year the stocks have produced the following stock returns:

Stock	Stock return
Stock A	12%
Stock B	39%
Stock C	-15%
Stock D	9%

2. The return on this stock portfolio is the weighted average of each of the component stocks' returns. Use the weights calculated above to determine the stock portfolio's return over the past year.

A. 8.25%

B. 7.125%

C. 10.50%

D. 11.25%

E. 13.875%
