Core Viewpoint - The article discusses the performance of private equity funds in the context of a bullish market trend in A-shares, emphasizing the importance of both offensive and defensive capabilities of these funds to capture investment opportunities and mitigate risks [1][3]. Offensive Capability (Upward Capture Rate) - Offensive capability measures how sensitive a fund is to market uptrends, with a higher value indicating stronger performance against the market. The upward capture rate is calculated as: (Cumulative return of the portfolio during the benchmark's up period + 1) / (Cumulative return of the benchmark during the up period + 1) - 1 [2]. Defensive Capability (Downward Capture Rate) - Defensive capability assesses how well a fund performs during market downturns, with a lower value being preferable.
