Perhaps the most frequently used estimator of the Capital Asset Pricing Model beta in finance is the Ordinary Least Squares estimate, obtained by regressing excess security return against excess market return, with an intercept. This paper shows that the Ordinary Least Squares estimator is...

We investigate the relation between downside beta and stock returns in a global context using more than 170 million daily return observations. Contrary to the findings in the U.S. equity market, we show that downside beta does not explain the cross-sectional differences in future and...

The beta space is a powerful way to map the investment strategies of semi-diversified investors. Three metrics define the beta space: regular or exogenous betas (x-βs), linked to macroeconomic cycles; endogenous betas (n-βs), related to innovation hazards; and a combination of the two — the...

We introduce a regime-conditional regression model to measure the risk profile of systematic investment strategies. We apply this model to classify systematic strategies into defensive and risk-seeking strategies with either positive or negative risk-premia alpha. Using the performance of the SG...

We give an explicit formulaic algorithm and source code for building long-only benchmark portfolios and then using these benchmarks in long-only market outperformance strategies. The benchmarks (or the corresponding betas) do not involve any principal components, nor do they require iterations....

We investigate the factor exposure of smart beta ETFs under model uncertainty using Bayesian variable selection. We find that smart beta ETFs have exposures to several factors, including size, value, momentum, quality, volatility/low beta, and dividend yield. The average return contribution of...

Using trading data from Finland and the US, I empirically show that investors tend to buy riskier stocks following realized losses. The measure of risk that the investors seem to pay attention to is the market beta of a stock. This behavior of buying higher beta stocks after a realized loss is...

Are REITs income stocks, only? Following Myers (1977) and Bernardo et al. (2007), we examine empirically REITs' unlevered betas, betas of growth options, betas of assets-in-lace and the difference between the latter two in detail for 1983-2012, and also for three sequential, distinct, than those...

We show the equivalence between the zero-beta version of a multi-factor arbitrage pricing model and a linear pricing model utilizing undiversified inefficient benchmarks in a given factor structure. The resulting linear model is a two-beta model, with one beta related to the inefficient...
