Behavioral biases like disposition effect and over-confidence have received much attention as a potential driver of numerous anomalies observed in the markets. Also, it has been argued that information uncertainty tends to exacerbate these biases and induce stronger irrational behavior among...

I study how trading motives in asset markets affect equilibrium outcomes and welfare. I focus on two types of trading motives -- informational and allocational. I show that while a fully separating equilibrium is the unique equilibrium when trading motives are known, multiple equilibria exist...

For optimal asset allocation, mean-variance investors must learn about the joint dynamics of new and existing asset classes, not only their profitability. Bitcoin's digital gold narrative provides a unique laboratory to test this hypothesis. We find that a decrease in investors' estimate on...

In this study, we employ a statistical arbitrage approach to demonstrate that momentum investment strategy tend to work better in periods longer than six months, a result different from findings in past literature. Compared with standard parametric tests, the statistical arbitrage method...

There has been considerable research into dynamic global tactical asset allocation (GTAA) strategies driven by simple measures of Valuation and Momentum applied to a baseline balanced portfolio of equities and fixed income (see Blitz and van Vliet 2008, Wang and Kochard 2011, Gnedenko and Yelnik...

This paper derives a robust online equity trading algorithm that achieves the greatest possible percentage of the final wealth of the best pairs rebalancing rule in hindsight. A pairs rebalancing rule chooses some pair of stocks in the market and then perpetually executes rebalancing trades so...

We present comprehensive evidence in support of giving liquidity equal standing to size, value/growth, and momentum as investment styles, as defined by Sharpe (1992). First, we show that financial market liquidity, as identified by stock turnover, is an economically significant indicator of...

The empirical asset pricing literature documents a myriad of anomalies. Accounting for the correlated and mean-reverting nature of these anomalies, I provide an explicit solution to the optimal dynamic investment problem of a risk-averse investor who trades in an arbitrary number of potentially...
