老师您好, 协会练习题有句话是说: "If we are evaluating two stocks with the same P/B, the one with the higher ROE is relatively undervalued, all else equal. These relationships have been confirmed through cross-sectional regression analyses." 为什么ROE高=>undervalued? 谢谢~

老师您好, 请问有句话"PEG does not account for differences in the duration of growth."是对的. 那请问: 1. 什么是duration of growth? 2. 哪些指标是account for differences in the duration of growth的呢? 谢谢!~

这里每年的roe不是应该不断变化的么，为何公式中的roe没有下标？1.站在0时点，如何知道1时点的roe？2.推导中每年的roe应该是变化的吧？

官网有个题目， Royappa suggests that the macroeconomic model with supply-side analysis using the Ibbotson–Chen format provides a better estimate for BTP’s risk premium. 公式是: [(1 + EINFL)(1 + EGREPS)(1 + EGPE) − 1] + EINC − Expected risk-free rate 请问Ibbotson–Chen format这个考点哪里? 谢谢 题目是官网的练习题.

老师您好, 这个观点: "Compared with the geometric mean return, the arithmetic mean return is consistent with the assumptions of single period models, such as the CAPM." 答案的解释是: The arithmetic mean return as the average one-period return best represents the mean return in a single period. The major finance models for estimating required return—in particular the CAPM and multifactor models—are single-period models, so the arithmetic mean, with its focus on single-period returns, appears to be a model-consistent choice. 请您解释下, 谢谢!

老师您好，请问这个statement 是正确还是错误的？

牛市价差，能不能先讲顺势再讲逆势 太乱

课件没有提到逆势的啊 再有构建组合，牛市价差策略 short put(X应该低)才不能被行权 组合一个long put(x应该高些)才好防范下跌风险。 我怎么觉得讲反了。

课件没有提到逆势的啊
