解释：
Market-neutral strategies have two inherent limitations:
1 Practically speaking, it is no easy task to maintain a beta of zero. Not all risks can be efciently hedged, and correlations between exposures are continually shifting.
2 Market-neutral strategies have a limited upside in a bull market unless they are “equitized.” Some investors, therefore, choose to index their equity exposure and overlay long/short strategies. In this case, the investor is not abandoning equity-like returns and is using the market-neutral portfolio as an overlay.
Therefore, both of the statements are correct.
不明白equitized意思，麻烦解释下，谢谢。
