Momentum strategies based on continuations in stock prices have become increas-ingly popular among academics, money managers, and investors in recent years. While there is little controversy on the profitability of momentum strategies, their implementation is afflicted with many difficulties....

We develop a shrinkage theory based framework for determining optimal port-folio weight constraints for minimum-variance portfolios in presence of parameteruncertainty. We propose to impose the set of constraints that yields the opti-mal trade-o between sampling error reduction and bias for the...

The main contribution of this work is to provide a dynamic general equilibrium model of asset allocation, allowing to reconcile economic theory with several puzzling contradictions recently pointed out in the literature: (i) the asset allocation puzzle, (ii) the observed time-variation in...

This paper suggests a factor model for carry trade strategies wherethe regression coeffcients are allowed to depend on market volatility and liquid-ity. Empirical results on daily data from 1995 to 2008 show that a typical carrytrade strategy has much higher exposure to the stock market and also...

By allowing for imperfectly informed markets and the role of private information, we offer newinsights about observed deviations of portfolio concentrations in domestic relative to foreignrisky assets, or “home bias”, from what standard finance models predict. Our model ascribesthe...

This paper analyzes the effects that uncertainty about economic fundamentalshas on aggregate trading volume. First, the trading volume of an investor facinga standard consumption portfolio choice problem is derived. It is found that if theparameters describing the investment opportunity set...

The paper examines a dynamic model of a financial market with endogenous asset prices determined by short run equilibrium of supply and demand. Assets pay dividends that are partially consumed and partially reinvested. The traders use fixed-mix investment strategies (portfolio rules),...

Assessments of investors’ risk appetite/aversion stance via indicators often yields resultswhich seem unsatisfactory (see e.g. Illing and Aaron (2005)). Understanding howsuch indicators work therefore seems essential for further improvements. The presentpaper seeks to contribute to this...

It is well known that asset allocation policy is the major determinant of fundperformance. However, there is substantial disagreement about the exactmagnitude of the contribution of asset allocation. Following the approach inIbbotson and Kaplan (2000), we use German and Swiss balanced mutualfund...
