This book proposes a new capital asset pricing model dubbed the ZCAPM that outperforms other popular models in empirical tests using US stock returns. The ZCAPM is derived from Fischer Black's well-known zero-beta CAPM, itself a more general form of the famous capital asset pricing model (CAPM)...

This paper provides cross-sectional tests of the Capital Asset Pricing Model (CAPM). To mitigate problems with noise in realized stock return series, we use a smoothed data series of average daily returns per month. Tests using U.S. stock returns for equal-weighted portfolios indicate that beta...

Due to a lack of supporting evidence, market beta in the widely-acclaimed Capital Asset Pricing Model (CAPM) is considered dead nowadays. In this paper we propose a novel approach for estimating market beta using the traditional market model. Upon deriving a covariance adjustment term, we...
