In a recent book, Kolari et al. developed a new theoretical capital asset pricing model dubbed the ZCAPM. Based on out-of-sample cross-sectional tests using U.S. stocks, the ZCAPM consistently outperformed well-known multifactor models popular in the finance literature. This paper presents...

Stock returns can have positive and negative sensitivity to the cross-sectional standard deviation of returns or return dispersion (RD). To capture asymmetric RD effects, we propose a new asset pricing model dubbed the ZCAPM that takes into account beta risk associated with the market factor and...

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...

This paper investigates abnormal standardized returns (ASRs) after major corporate events. Dutta, Knif, Kolari, and Pynnonen (2018) have shown that the ASR t-test has superior size and power compared to traditional test statistics. Based on this new test statistic compared to traditional test...

This article re-examines the issue of cross-sectional correlation. Kolari and Pynnonen (2010) find that, in the case of event-date clustering with the same event window for all firms, relatively low cross-sectional correlation among abnormal returns can seriously bias standard tests to...
