concentration level

NO.PZ2023010903000016

问题如下:

McMahon observes that the benchmark used for the US large-cap equity component is a price-weighted index containing 150 stocks. The benchmark’s Herfindahl–Hirschman Index (HHI) is 0.0286.

Based on its HHI, the initial US large-cap benchmark most likely has:

选项:

A.

a concentration level of 4.29

B.

an effective number of stocks of approximately 35

C.

individual stocks held in approximately equal weights

解释:

The HHI measures stock concentration risk in a portfolio, calculated as the sum of the constituent weightings squared:


Using the HHI, one can estimate the effective number of stocks, held in equal weights, that would mimic the concentration level of the respective index. The effective number of stocks for a portfolio is calculated as the reciprocal of the HHI. The HHI is 0.0286; the reciprocal (1/0.0286) is 34.97.

Therefore, the effective number of stocks to mimic the US large-cap benchmark is approximately 35.
