Robert Arnott and Jason Hsu We model a continuous time one factor economy where stock prices are noisy proxies of the informationally efficient stock values. The pricing error process is modeled as a mean-reverting process, which gives us a well-defined notion of over-pricing (positive pricing error) and under-pricing (negative pricing error) in the market. We… Read more

A Model of Fund Growth For Managed Futures: Evidence of Managerial Skill
Paul Lajbcygier Fund size is an essential component of a funds overall value. In this work, we argue that growth in fund size results from managerial skill. To test this argument, we estimate a model that links fund growth to performance characteristics. We use the model to isolate significant performance characteristics and confirm that the… Read more

Bayes vs. Resampling: A Rematch
Campbell R. Harvey, John C. Liechty and Merrill W. Liechty We replay an investment game that compares the performance of a player using Bayesian methods for determining portfolio weights with a player that uses the Monte Carlo based resampling approach advocated in Michaud (Efficient Asset Management. Boston: Harvard Business School, 1998). Markowitz and Usmen (Journal… Read more
Estimation Error and Portfolio Optimization: A Resampling Solution
Richard Michaud and Robert Michaud Markowitz (1959) mean-variance (MV) portfolio optimization has been the practical standard for asset allocation and equity portfolio management for almost 50 years. However it is known to be overly sensitive to estimation error in risk-return estimates and have poor out-of-sample performance characteristics. The Resampled Efficiency (RE) techniques presented in Michaud… Read more
INSIGHTS: Why is There a Home Bias? Count the Teeth!
Jitka Hilliard and Jimmy E. Hilliard Under somewhat idealized conditions, investors would achieve the best risk return tradeoff by allocation equity investment in each country equal to its percentage share of world equity capitalization. But factual evidence confirms that domestic investors prefer domestic stocks. For example, domestic investors allocate about 90 percent of their portfolios… Read more
