对冲基金资产权重问题求助
如果一个对冲基金采取长短仓策略,即买进看涨/卖出看跌,那么各种资产买进卖出的权重比例怎么来确定呢?资产组合的有效前沿理论还适用吗?如果有效前沿计算出来的权重比例可以是负的(即可以卖空),但不一定符合你认为应该卖出的,怎么来决定呢?

It depends on whether you are a fundamental long short fund or a quantitative/systematic manager. In fact, most managers in reality use a bottom up fundamental stock picking strategy. Portfolio optimization is only used to balance the portfolio. And of coz you can set constraint on your longs and shorts.
