问题如下:
Wang uses a cost–benefit approach to rebalancing and recommends that global equities have a wider rebalancing range than the other asset classes.
Wang’s approach to rebalancing global equities is consistent with:
选项:
A.the Wang’s being risk averse.
B.global equities’ having higher transaction costs than other asset classes.
C.global equities’ having lower correlations with other asset classes.
解释:
B is correct.
考点:影响rebalancing range的因素.
解析:rebalancing corridor width与以下因素正相关:交易成本、税收、风险容忍度、与其它资产类型的相关性。与以下因素负相关:自身的波动率,其它资产类型的波动率。
global equities有更宽的rebalancing range,所以可能的原因为:投资者风险容忍度高,交易成本偏高,与其它资产类型的相关性高。所以只有B正确。
为什么一定是投资者投资风险容忍度高才corridor 宽呢,如果是risk averse的投资者,亏损达到20%以上他也不舍得调仓,不也会达到corridor宽的效果吗。
