问题如下:
An analyst gathers the following data for an equally-weighted index:
The return on the index over the period is:
选项:
A.4.2%.
B.6.8%.
C.7.1%.
解释:
C is correct.
With an equal-weighted index, the same amount is invested in each security. Assuming $1,000 is invested in each of the three stocks, the index value is $3,000 at the beginning of the period and the following number of shares is purchased for each stock:
Security A: 50 shares
Security B: 20 shares
Security C: 38.46 shares.
Using the prices at the beginning of the period for each security, the index value at the end of the period is
$3,213.8: ($22 × 50) + ($48 × 20) + ($30 × 38.46). The price return is $3,213.8/$3,000 – 1 = 7.1%.
老师你好,题目中说到是price return我就按total return算了但是看了老师回答其他同学的解析是按price return来的,想问是怎么知道按price return算的呢
