At the beginning of the month, you owned $8,000 of General Dynamics, $7,000 of Starbucks, and $5,000 of Nike. The monthly returns for General Dynamics, Starbucks, and Nike were 6.80 percent, −1.52 percent, and −0.62 percent. What is your portfolio return?

Answer:

= $406.6

Explanation:

To calculate return of portfolio we first calculate weight of each asset

this can be done by finding total investment and then dividing each asset by total investment.

Total investment = 8000 + 7000 + 5000 = $20,000

General Dynamics     8000/20000 = 0.4 = W1

Starbucks                    7000/20000 = 0.35 = W2

Nike                             5000/20000 = 0.25 = W3

Now for portfolio return we can use the formula

P(r) = W1 * (Return on W1 asset) + W2 * (Return on W2 asset) + W3 * (Return on W3 asset)

So,

P(r) = 0.4 * (0.0680) + 0.35 * (-0.0152) + 0.25 * (-0.0062)

This gives us

Total Return % = 0.02033 or 2.033%

Simply multiply this cumulative weight to total portfolio worth

Total Return in $ = 0.02033 * 20000  = $406.6

Hope that helps.
