multi-factor实施long/short策略的drawbacks
这一段读不懂:
removing the risk associated with the market factor implies that the long/short product would most likely be used as an overlay on long-only mandates.为啥多因子多空策略会变成只做多?
the mandate may also be leveraged(more than 1*long and 1*short) to maximize the potential return per dollar of capital. 括号里是指啥,类似卖空50买入150产生的超额买卖现象么?
