问个很菜的问题

equitizing maket neutral strategy 和 alpha beta seperation这两个的区别在哪?感觉好像是一个东西

有看到说:alpha beta seperataion: 在其中的long short strategy中,有些不是market neutral, 但从strategy的运用方法来看,和equitizing market neutral strategy 好像没有区别啊。

还有,equitizing market neutral strategy是2alpha+1beta。
        但alpha beta seperation 为何是 1alpha+1beta。 既然在实施过程中,含有long short strategy,不是应该有两个alpha吗?


期待解答,多谢!

equitizing market neutral strategy: add the systematic risk by holding equity future.

alpha beta seperation:
for beta: gain a long systematic risk exposure through a low-cost index, (same as equitizing market neutral strategy)

for alpha: using a pair trade, namely buy undervalued stocks and short overvlaued stock, elminiating the expected systematic risk.
