嗨，努力学习的PZer你好：
最后一句的解释意思，谢谢
Chen prefers an approach that emphasizes security-specific factors, engages in factor timing, and typically leads to portfolios that are generally more concentrated than those built using a systematic approach
这句话的含义是：
陈更喜欢强调security-specific factors，关注择时，通常会导致投资组合比使用量化方法构建的投资组合更集中。
所以discretionary更加集中，而systematic选股更加分散吗？
是的。
security-specific factors + 择时 = bottom up + discretionary。
bottom up + discretionary 方法的集中度，可以比bottom up + systematic的集中度更高。
