答案是选择market neutral long/short strategy,因为此战术是beta=0
但我印象中market neutral是beta=1,而short extension strategy才是beta=0,这是怎么回事呢?
market neutra是所谓的130/30战术吧,买入100的index future,然后30做long/short,这样正好是1
short extension不买入index future,直接做30/30的long/short
业界不都是这么做吗

仍然是恰恰相反,130/30你的净头寸仍然是100,指数涨你也涨,怎么能叫market neutral呢?所谓的market neutral就是30/30,而130/30恰恰是short extension
