问题如下：
Laubach states that that the board is interested in following a passive approach for some or all of the equity allocation. In addition, the board is open to approaches that could generate returns in excess of the benchmark for part of the equity allocation. McMahon suggests that the board consider following a passive factor-based momentum strategy for the allocation to international stocks.
Compared with broad-market-cap weighting, the international equity strategy suggested by McMahon is most likely to:
选项：
A.concentrate risk exposure
be based on the efficient market hypothesis
overweight stocks that recently experienced large price decreases
解释：
Compared with broad-market-cap weighting, passive factor-based strategies tend to concentrate risk exposure, leaving investors vulnerable during periods when the risk factor (e.g., momentum) is out of favor.
老师，为什么选A：
1.这道题的判断A的思路主要来自于哪个点？
2.international不是应该比broad-market-cap更具有投资范围广和分散化的效果么？
3.选项C怎么判断？
