Stapleton then begins a description of factor-based strategies. These include common equity factors, such as value, size, and quality, and they can be used either in place of or to complement market-cap-weighted indexing. She points out that relative to market-cap weighting, factor-based strategies tend to diversify risk exposures; are transparent in terms of factor selection, weighting, and rebalancing; but can be copied by other investors, which can reduce the advantages of a strategy. Q. When comparing factor-based strategies relative to the market-cap weighting of an index, Stapleton’s comments are most likely: A. incorrect regarding transparency. B. correct. C. incorrect regarding risk exposure. 請問答案為什麼是Ｃ呢？Factor-based strategy 不是也能達到risk reduction的作用嗎？

請問在CFA practice question中 Q7 "value factor funds seek to lower downside risk;" solution 說 "is incorrect because value factor funds focus on valuation measures, not volatility." 選擇value stock不是因為lower valuation compared with growth stock, 然後price drawdown 的程度較小，所以lower downside risk?
