Undiversifiable (or systematic risk) has long been an enemy of investors. Many countercyclical strategies have been developed to counter this. However, like all insurance types, these strategies are generally costly to implement, and over time can significantly reduce portfolio returns in long...

This paper studies the effect of new fund flows on investment behavior and the resulting equilibrium price of risk. The Small Fund Industry model shows equilibria with overinvestment in unprofitable and underinvestment in profitable investment opportunities. The Large Fund Industry model derives...

The general conclusion of a very large literature on the equity premium puzzle is that the simplest version of the consumption-based asset pricing model (C-CAPM) with time-additive, power utility is inconsistent with the data. I show that this conclusion is premature and the simplest version can...

The existence of a premium to momentum portfolios, formed by buying recent winners and selling recent losers is widely accepted, although the source of the returns remains controversial. It remains a focus of behavioural finance. We focus on one set of explanations, based on prospect theory,...

Modern Portfolio Theory, the Capital Asset Pricing Model, and the Efficient Market Hypothesis are cornerstone concepts in both academic and professional curricula. In spite of their long history and reputation, the CAPM and its extensions do not yield satisfactory empirical results. We argue...

Recent evidence indicates that market model alphas are stronger predictors of mutual fund flows than alphas with other models. Berk and van Binsbergen (2016) claim that this evidence indicates CAPM is the best asset pricing model but Barber, Huang and Odean (2016) (BHO) claim it is evidence...

We find that when measured in terms of dollar-turnover, and once beta-neutralised and Low-Vol neutralised, the Size Effect is alive and well. With a long term t-stat of 5.1, the “Cold-Minus-Hot” (CMH) anomaly is certainly not less significant than other well-known factors such as Value or...

We exploit the domestic portfolios of US mutual funds to provide microeconomic evidence that investors are more likely to liquidate geographically remote investments at times of high aggregate market volatility. This has important implications for asset prices. The valuations of stocks with ex...

Theory has linked price momentum with price reversals (Barberis, Shleifer, and Vishny (1998), Daniel, Hirshleifer, and Subrahmanyam (1998), and Hong and Stein (1999)). The models generally rely on behavioral descriptions of irrational investors who push prices beyond their fundamental value thus...

Decision-makers typically rely on informative starting points that are somewhat incorrect and then attempt to make appropriate adjustments. Such reliance on informative starting points may be an optimal response of a Bayesian decision-maker who faces finite computational resources (Lieder et al...
