老師，能否詳細(xì)解釋一下書本151頁，第十三題答案是什么意思？This results from the fact that the factors typically represent what is referred to as a zero (dollar) investment or self- financing investment, in which the underperforming attri-bute is sold short to finance an offsetting long position in the better- performing attribute.

這題有點(diǎn)不太容易理解，比如有一個(gè)portfolio的value在minimum level附近，時(shí)高時(shí)低，豈不是經(jīng)常要包含計(jì)算又剔除，這樣對(duì)composite的業(yè)績報(bào)送豈不是很不穩(wěn)定。這樣的業(yè)績時(shí)高時(shí)低，跌下去了就不用報(bào)送，漲上來了又報(bào)送。感覺不是很合理。
