what does it mean? "is to behavioral finance as... anomaly is to modern..."

Question

Building on Chapter 6’s measures of risk aversion, Chapter 7 explores both the equity risk premium and the econometric puzzle to which that premium has given rise. The equity premium puzzle is to behavioral finance as the low-volatility anomaly is to modern portfolio theory and the conventional capital asset pricing model: Without resolving contradictions of this magnitude, many of the theoretical suppositions of mathematical and behavioral finance will be squarely contradicted by the behavior of real markets and real investors.

Answer 1

نسبت equity premium puzzle به سرمایه گذاری رفتاری مثل نسبت ناهنجاری با بی ثباتی پایین است به نظریه سبد سهام مدرن.
