A Model-Free CAPM with High Order Risks


30 Oct 2014 (Thu)


3.00 - 4.30pm


RMI Executive Seminar Room 21 Heng Mui Keng Terrace, I3 Building, Level 4


Allowing for non-normality in market returns, we present an approximate capital asset-pricing model in which besides first-order co-moment risks, higher-order co-moment risks are also important for pricing individual stocks. We find that the second-order risk is significantly and negatively priced and contributes to the inverse U-shaped relation between expected returns and betas. We then construct three risk factors with each to mimic second-order risk premiums. We show that each of our newly constructed second-order risk factors is related to the market variance risk premium. More importantly, a two-factor model consisted of a market factor and one of our second-order risk factors can fully explain the total (idiosyncratic) volatility puzzle and the MAX puzzle and partially explain the betting against beta premium.
