同学,你好:
behavioral portfolio theory (BPT) 其实就是想说下面这件事情。
The optimal portfolio under BPT can differ from the perfectly diversified portfolio of Markowitz. In Markowitz’s portfolio theory, risk-averse investors construct diversified portfolios based on mean–variance analysis and consideration of the covariance between assets.
They are concerned about the expected return and variance of the portfolio as a whole. In behavioral portfolio theory, however, investors construct their portfolios in layers and expectations of returns and attitudes toward risk vary between the layers.
