Active Portfolio Management--A Quantitative Approach for Producing Superior Returns and Controlling Risk.
https://bbs.pinggu.org/thread-1532601-1-1.html (英文版)
2.今天你阅读到的有价值的内容段落摘录
(1) The goal of active management is trying to make model expected returns better than consensus expected returns while bearing the same risk.
(2) The CAMP serves as the source of consensus expected returns. And CAPM forecasts of expected returns and build optimal mean/variance portfolios, those portfolios will consist simply of positions in the market and the risk-free asset.
(3) Historical beta(or Realized beta) is derived from regression, while forward-looking beta is always predicted by Barra model.
(4) Under the CAPM, the expected residual return on any stock or portfolio is zero. Expected excess returns are proportional to the stock’s (or portfolio’s) beta.
3.今天你阅读到的有价值信息的自我思考点评感想
(1) 关于CAMP模型背后的逻辑, 作者用市场中三个投资者的行为来举例,生动利于理解。
(2) 用Barra模型预测出来的Beta与历史的Beta差异相对较小,说明Barra模型有非常强的预测力。
