This paper studies portfolio optimization through improvements of ex-ante conditional covariance estimates. We use the cross-section of stock returns over a 52-year sample to analyze trading performance by implementing the machine learning algorithm of hierarchical clustering. We find that...

We use a sample of option prices, and the method of Bakshi, Kapadia and Madan (2003), to estimate the ex ante higher moments of the underlying individual securities' risk-neutral returns distribution. We find that individual securities' volatility, skewness, and kurtosis are strongly related to...

The work of Treynor and Mazuy (1966) spawned an extensive literature on returns-based measurement of portfolio performance which distinguishes between a manager's ability to act on information specific to an individual asset (asset selection) and ability to forecast systematic risk premiums and...

We treat expenditures that create intangible assets as investments and instead of expensing them, we add them back to earnings when measuring the return on equity of firms while constructing the profitability factor in the Fama and French (2015) five factor model. The profitability factor we...

The paper seeks to lay out a stock-flow-based theoretical framework that provides a foundation for a general theory of pricing. Contemporary marginalist economics is usually based on the assumption that prices are set in line with the value placed on goods by consumers. It does not take into...

Empirical measures of world consumption growth risk have failed to rationalize the cross-section of country equity returns. We propose a new factor, termed "the global consumption factor", to explain the patterns in risk premiums on international equity markets. We identify this factor as the...

We propose a single-factor asset pricing model based on an indicator function of consumption growth being less than its endogenous certainty equivalent. This certainty equivalent is derived from generalized disappointment aversion preferences, and it is located approximately one standard...

We develop a four-factor model intended to capture size, value, and credit rating transition patterns in excess returns for a panel of predominantly mid- and large-cap entities. Using credit transition matrices and rating histories from 48 US issuers, we provide evidence to support a...

Many modern macro finance models imply that excess returns on arbitrary assets are predictable via the price-dividend ratio and the variance risk premium of the aggregate stock market. We propose a simple empirical test for the ability of such a model to explain the cross-section of expected...

Generalizing the idea that price momentum can be explained by different levels of uncertainty inherent in the information structure, we implement signal-specific differences in uncertainty in a Kyle type model of strategic trading. We derive the equilibrium in a single-auction setting as well as...
