01 ABSTRACT
The post is a regular roundup of quantitative research links by Quantocracy, featuring a discussion of the relationship between CAPM and Markowitz portfolio choice. It notes that Beta originally served to compress the covariance matrix but later became the equilibrium measure in CAPM. The authors' view suggests this evolution has profound implications for modern portfolio theory, but no new empirical data or specific research findings are provided.
