Optimal investment of firms implies that expected stock returns are tied with the expected marginal benefit of investment divided by the marginal cost of investment. Winners have higher expected growth and expected marginal productivity (two major components of the marginal benefit of...

Q-theory predicts that investment frictions steepen the relation between expected returns and firm investment. Using financing constraints to proxy for investment frictions, we document only weak evidence that the investment-to-assets and asset growth effects in the cross-section of returns are...

We question a deep-ingrained doctrine in asset pricing: if an empirical characteristic-return relation is consistent with investor “rationality,” the relation must be “explained” by a risk factor model. The investment approach changes the big picture of asset pricing. Factors formed on...

We offer an investment-based interpretation of price and earnings momentum. The neoclassical theory of investment implies that expected stock returns are tied with the expected marginal benefit of investment divided by the marginal cost of investment. Winners have higher expected growth and...

A deep-ingrained doctrine in asset pricing says that if an empirical characteristic-return relation is consistent with investor “rationality,” the relation must be “explained” by a risk (factor) model. The investment approach questions the doctrine. Factors formed on characteristics are...

This paper shows that the notion of rate of return is best understood through the lens of the average-internal-rate-of-return (AIRR) model, first introduced in Magni (2010a). It is an NPV-consistent approach based on a coherent definition of rate of return and on the notion of Chisini mean, it...

A detailed treatment of aggregation and capital heterogeneity substantially improves the performance of the investment CAPM. Firm-level predicted returns are constructed from firm-level accounting variables and aggregated to the portfolio level to match with portfolio-level stock returns....

This paper proposes a new discounted cash flows' valuation setup, and derives a general expression for the tax shields' discount rate. This setup applies to any debt policy and any cash flow pattern. It only requires the equality at any time between the assets side and the liabilities side of...

This paper studies how investor heterogeneity determines equilibrium debt maturity in a model with default. The traditional representative investor assumption is a special case where a weak form of the Modigliani-Miller theorem holds; allocations with either all long- or all short-term debt are...

Integrating national accounting with financial accounting, we provide firm-specific estimates of current-cost capital stocks for the entire Compustat universe, as well as an array of estimates of investment flows, economic depreciation rates, and capital and investment price deflators. The...
