Answer:
0.4371 and 0.2185
Explanation:
For computing the portfolio weight, first we have to determine the total value which is shown below:
For Yahoo:
220 shares × $30 = $6,600
For General motors:
110 shares × $30 = $3,300
For Standard and Poor's Index Fund:
40 shares × $130 = $5,200
So, the total value would be
= $6,600 + $3,300 + $5,200
= $15,100
So, the portfolio weight of YHOO and GM would be
= $6,600 ÷ $15,100 = 0.4371
And, for GM, it would be
= $3,300 ÷ $15,100 = 0.2185
