The optimal portfolio strategy is developed for an investor who has detected an asset pricing anomaly but is not certain that the anomaly is genuine rather than merely apparent. The analysis takes account of the fact that the parameters of both the underlying asset pricing model and the anomalous returns are estimated rather than known. The value that an investor would place on the ability to invest to exploit the apparent anomaly is also derived and illustrative calculations are presented for the FamaFrench SMB and HML portfolios, whose returns are anomalous relative to the CAPM. An asset pricing anomaly is a statistically significant difference between the realized average returns associated with certain characteristics of securities, or on portfolios of securities formed on the basis of those characteristics, and the returns that are predicted by a particular asset pricing model. What is anomalous with respect to one model may be consistent with the predictions of other asset pricing models. For example, an excess return associated with a security’s dividend yield is anomalous with respect to the basic Capital Asset Pricing Model but is consistent with extensions that incorporate investor taxes. Some anomalies are inconsistent with any known rational asset pricing model; they appear to represent “money left on the table”; such examples include the

Japanese stock returns are even more closely related to their booktomarket ratios than are their U.S. counterparts, and thus provide a good setting for testing whether the return premia associated with these characteristics arise because the characteristics are proxies for covariance with priced factors. Our tests, which replicate the Daniel and Titman ~1997! tests on a Japanese sample, reject the Fama and French ~1993! threefactor model, but fail to reject the characteristic model. FINANCIAL ECONOMISTS HAVE EXTENSIVELY STUDIED the crosssectional determinants of U.S. stock returns, and contrary to theoretical predictions, find very little crosssectional relation between average stock returns and systematic risk measured either by market betas or consumption betas. In contrast, the crosssectional patterns of stock returns are closely associated with characteristics like booktomarket ratios, capitalizations, and stock return momentum. 1 More recent research on the crosssectional patterns of stock returns documents size, booktomarket, and momentum in most developed countries.

We develop models of stochastic discount factors in international economies that produce stochastic risk premiums and stochastic skewness in currency options. We estimate the models using timeseries returns and option prices on three currency pairs that form a triangular relation. Estimation shows that the average risk premium in Japan is larger than that in the US or the UK, the global risk premium is more persistent and volatile than the countryspecific risk premiums, and investors respond differently to different shocks. We also identify highfrequency jumps in each economy, but find that only downside jumps are priced. Finally, our analysis shows that the risk premiums are economically compatible with movements in stock and bond market fundamentals.

This paper takes a shrinkage approach to examine empirical implications of aversion to model uncertainty. The shrinkage approach explicitly shows how predictive distributions incorporate data and prior beliefs. It enables us to solve the optimal portfolio for uncertaintyaverse investors. Aversion to uncertainty about the CAPM leads investors to hold a portfolio that is not meanvariance efficient for predictive distributions. However, meanvariance efficient portfolios corresponding to extremely strong beliefs in the FamaFrench model are approximately optimal for uncertaintyaverse investors. The empirical Bayes approach does not deliver optimal portfolios when investors are averse to uncertainty. The diversified world market portfolio is optimal for uncertaintyaverse investors, and U.S. investors ’ home bias is robust to the belief or disbelief in the world CAPM.

The fragility of the CAPM has led to a resurgence of research that frequently uses trading strategies based on sorting procedures to uncover relations between firm characteristics (such as “value ” or “glamour”) and equity returns. We examine the propensity of these strategies to generate statistically and economically significant profits due to our familiarity with the data. Under plausible assumptions, datasnooping can account for up to 50 percent of the insample relations between firm characteristics and returns uncovered using single (oneway) sorts. The biases can be much larger if we simultaneously condition returns on two (or more) characteristics.

Value and momentum ubiquitously generate abnormal returns for individual stocks within several countries, across country equity indices, government bonds, currencies, and commodities. We study jointly the global returns to value and momentum and explore their common factor structure. We find that value (momentum) in one asset class is positively correlated with value (momentum) in other asset classes, and value and momentum are negatively correlated within and across asset classes. Liquidity risk is positively related to value and negatively to momentum, and its importance increases over time, particularly following the liquidity crisis of 1998. These patterns emerge from the power of examining value and momentum everywhere simultaneously and are not easily detectable when examining each asset class in isolation.
Operating Leverage, Stock Market Cyclicality and the CrossSection of Returns

I use a puttyclay technology to explain several asset market facts. The key mechanism is as follows: a one percent increase in revenues leads to a morethanone percent increase in profits, since labor costs don’t move oneforone. This amplification is greater for plants with low productivity for which the average profit margin (revenue minus costs) is small. This “operating leverage ” effect implies that low productivity plants benefit disproportionately from business cycle booms. These plants have thus higher systematic risk and higher average returns. This model can help explain the empirical findings of Fama and French (1992), and more generally the sources of differences in market betas across firms. I obtain supporting evidence for the mechanism using firm and industrylevel data. The aggregate effect follows from trend growth: lowproductivity plants outnumber highproductivity plants, making the aggregate stock market procyclical. I examine these aggregate implications and find that this model generates a volatile stock market return that predicts the business cycle.

... marks the birth of asset pricing theory (resulting in a Nobel Prize for Sharpe in 1990). Before their breakthrough, there were no asset pricing models built from first principles about the nature of tastes and investment opportunities and with clear testable predictions about risk and return. Four decades later, the CAPM is still widely used in applications, such as estimating the cost of equity capital for firms and evaluating the performance of managed portfolios. And it is the centerpiece, indeed often the only asset pricing model taught in MBA level investment courses. The attraction of the CAPM is its powerfully simple logic and intuitively pleasing predictions about how to measure risk and about the relation between expected return and risk. Unfortunately, perhaps because of its simplicity, the empirical record of the model is poor – poor enough to invalidate the way it is used in applications. The model’s empirical problems may reflect true failings. (It is, after all, just a model.) But they may also be due to shortcomings of the empirical tests, most notably, poor proxies for the market portfolio of invested wealth, which plays a central role in the model’s predictions. We argue, however, that if the market proxy problem invalidates tests of the model, it also invalidates most applications, which typically borrow the market proxies used in empirical tests. For perspective on the CAPM’s predictions about risk and expected return, we begin with a brief
