老师好 这里manager 3, 1) little appetite for idiosyncratic risks within sectors 是指行业内部只有系统性风险吗,这说明、要体现什么?是要说明是discretionary 吗?
2)discretionary and idiosynctric risk 有什么关系?discretionary 是more concentrated portofolio 这样是否idiocyncratic risk 会高?
3)discretionary 要记哪些? 能想到的是discretionary 做的是 fundemental ( 有人脑判断), diversified or concentrated , 需要择时,judegment on small set of securities, more concentrated portfolio, less formal approach, depth understanding of a firm's operation, 关于discretionary还有需要记什么 ? 谢谢。
