Question The index weighting that results in portfolio weights shifting away from securities that have increased in relative value toward securities that have fallen in relative value whenever the portfolio is rebalanced is most accurately described as:选项：
A.float-adjusted market-capitalization weighting. B.fundamental weighting. C.equal weighting.解释：
SolutionB is correct. Fundamentally weighted indexes generally will have a contrarian “effect” in that the portfolio weights will shift away from securities that have increased in relative value and toward securities that have fallen in relative value whenever the portfolio is rebalanced.
A is incorrect. In the float-adjusted market-capitalization weighting scheme, the constituent securities whose prices have risen the most (or fallen the most) have a greater (or lower) weight in the index.
C is incorrect. In an equal weighting scheme, securities that constitute the largest fraction of the target market value are underrepresented and securities that constitute a small fraction of the target market value are overrepresented. This weighting scheme does not consider fundamental measures in rebalancing.
