→ ken90007: traditional cap-weighted index。 12/30 11:32
GDP-weighted indexes are significantly more positively exposed to Size, Value,
Betting-Against-Beta and Profitability factors, while significantly more
negatively exposed to the Quality-Minus-Junk and Investment factor. When
adjusting the returns of a GDP-weighted index for these risk factor exposures,
the GDP-weighted index does not generate positive alpha and therefore loses
its superiority over cap-weighted indexes.
==========================================================
如果相信factor模型的話
與其 GDP-weighted,不如直接對factor曝險
當然如果你不相信factor的話,這篇論文對你大概沒什麼意義
