A recent book by Kolari, Liu, and Huang (KLH) (2021) developed a new theoretical capital asset pricing model dubbed the ZCAPM, which outperformed well-known multifactor models in cross-sectional tests using U.S. stocks. This paper extends their analyses by employing a longer sample period from...

Kolari, Liu, and Huang (2021) recently proposed and empirically tested a new asset pricing model dubbed the ZCAPM that consistently outperformed popular multifactor models using U.S. stock returns. Is the ZCAPM a false discovery? As verification, this paper provides international stock return...

A growing list of proposed factors is causing factor and model selection problems in asset pricing research and practice. This paper mitigates these problems by combining the CRSP market index with multiple factors to create a single multifactor market index. Empirical tests of multifactor...

This paper combines the CRSP market index with multiple factors to create a single multifactor market index. Empirical tests of different multifactor market indexes indicate that: (1) Sharpe ratios substantially increase and GRS test statistics decrease as multifactors are incrementally added to...
