The value anomaly arises naturally in the neoclassical framework with rational expectations. Costly reversibility and countercyclical price of risk cause assets in place to be harder to reduce, and hence are riskier than growth options especially in bad times when the price of risk is high. By linking risk and expected returns to economic primitives, such as tastes and technology, my model generates many empirical regularities in the cross‐section of returns; it also yields an array of new refutable hypotheses providing fresh directions for future empirical research.

Unsustainable credit growth leads to financial stability risks, with real repercussions. But what is unsustainable? In this paper we suggest that the balance between the growth in mortgage credit and business credit is a key factor in post-crisis macroeconomic vulnerability. The sample-average rise in credit composition (the share of household mortgage credit in total credit) in 51 economies in the five years before the 2007 global financial crisis is associated with a 2.1% average growth loss in the five years after the crisis. This finding is robust for total-credit growth and for post-crisis fiscal and monetary policy responses. Delving into the channels, we find that larger changes in credit composition before the crisis are linked to less efficient capital reallocation and larger investment cutbacks afterwards.

Interpreting accruals as working capital investment, we hypothesize based on "q"-theory that firms optimally adjust their accruals in response to discount rate changes. A higher discount rate means less profitable investments and lower accruals, and a lower discount rate means more profitable investments and higher accruals. Our evidence supports this optimal investment hypothesis: (1) adding an investment factor into standard factor regressions substantially reduces the magnitude of the accrual anomaly, often to insignificant levels; (2) accruals covary negatively with discount rate estimates from the dividend discounting model, and for the most part, with estimates from the residual income model; (3) accruals with low accounting reliability covary more with capital investment than accruals with high accounting reliability; and (iv) expected returns to accruals-based trading strategies are time-varying, suggesting that the deterioration of the accrual effect in recent years might be temporary and likely to mean-revert in the near future.

In the investment theory, firms with high expected investment growth earn higher expected returns than firms with low expected investment growth, holding investment and expected profitability constant. Building on cross-sectional growth forecasts with Tobin’s q, operating cash flows, and change in return on equity as predictors, an expected growth factor earns an average premium of 0.84% per month (t = 10.27) in the 1967–2018 sample. The q5 model, which augments the Hou–Xue–Zhang (2015, Rev. Finan. Stud., 28, 650–705) q-factor model with the expected growth factor, shows strong explanatory power in the cross-section and outperforms the Fama–French (2018, J. Finan. Econom., 128, 234–252) six-factor model.

Many recently proposed, seemingly different factor models are closely related. In spanning tests, the q-factor model largely subsumes the Fama–French five- and six-factor models, and the q5 model subsumes the Stambaugh–Yuan four-factor model. Their “mispricing” factors are sensitive to the construction procedure, and once replicated via the traditional approach, are close to the q-factors, with correlations of 0.8 and 0.84. Finally, consistent with the investment CAPM, valuation theory predicts a positive relation between the expected investment and the expected return.

Within the standard search and matching model, time-to-build implies that high aggregate risk premiums should forecast low employment growth in the short run but high employment growth in the long run. If there is also time-to-plan, high risk premiums should forecast low net hiring rates in the short run but high net hiring rates in the long run. Our evidence indicates two-quarter time-to-build in the aggregate payroll data, no time-to-plan in the aggregate hiring data, but two-quarter time-to-plan in the job creation data for manufacturing firms. High payroll growth and high net job creation rate in manufacturing also forecast low stock market excess returns at business cycle frequencies.

Recent winners have temporarily higher loadings than recent losers on the growth rate of industrial production. The loading spread derives mostly from the positive loadings of winners. The growth rate of industrial production is a priced risk factor in standard asset pricing tests. In many specifications, this macroeconomic risk factor explains more than half of momentum profits. We conclude that risk plays an important role in driving momentum profits. The Author 2008. Published by Oxford University Press on behalf of The Society for Financial Studies. All rights reserved.

The anomalies literature in capital markets research in finance and accounting is based (almost) exclusively on average realized returns. In contrast, we construct accounting-based expected returns for dollar-neutral long-short trading strategies formed on a wide array of anomaly variables, including book to market, size, composite issuance, net stock issues, abnormal investment, asset growth, investment to assets, accruals, earnings surprises, failure probability, return on assets, and short-term prior returns. Our findings are striking. Except for the value and the size premiums, the cost of equity estimates differ drastically from the average realized returns.

Most anomalies fail to hold up to currently acceptable standards for empirical finance. With microcaps mitigated via NYSE breakpoints and value-weighted returns, 65% of the 452 anomalies in our extensive data library, including 96% of the trading frictions category, cannot clear the single test hurdle of the absolute t-value of 1.96. Imposing the higher multiple test hurdle of 2.78 at the 5% significance level raises the failure rate to 82%. Even for replicated anomalies, their economic magnitudes are much smaller than originally reported. In all, capital markets are more efficient than previously recognized.
