对于题干里这句话我不是很理解:increase the portfolio's diversification across OTHER NON-MARKET factors.
我的理解是,使用market neutral strategy是提供了diversification in the sense of market risk factor,就像其他long-short strategy一样,是reduce market risk但是profit from other risk factors,例如买一只小盘股,卖一只大盘股,marke risk被neutralize掉了,diversification is achieved,但是在size这个factor上不是take risk and profit了吗?这怎么能算是increase diversification across other(size) factors呢?
