Debt/Equity Ratio and Expected Common Stock Returns

TL;DR
Expected stock returns rise with the debt/equity (leverage) ratio, even after controlling for market beta and firm size. The premium is much larger in January and is robust to the choice of market proxy and estimation method. Bhandari argues it is too large to be a simple risk premium — an early leverage anomaly.
What anomaly it documents
Predictor: book leverage = noncommon-equity liabilities / market value of equity.
Direction: positive — high-leverage firms earn higher average returns.
Shape: monotone increasing across leverage groups; strongly concentrated in January.
OSAP predictor: Leverage.
How to construct it
Sorting variable: debt/equity ratio (total liabilities to market equity).
Universe: NYSE common stocks (1948–1979 in the original study).
Portfolio formation: rank into leverage groups, controlling for beta and size.
Long / short: long high leverage, short low leverage.
Weighting: equal- or value-weighted within groups.
Rebalancing: annual, after accounting data become available.

Why it might work
Financial risk: leverage amplifies equity risk, so levered firms should earn more — but Bhandari finds the premium larger than beta justifies.
Distress / mispricing: leverage proxies for financial distress that the market may misprice.
Value overlap: high-leverage firms tend to be cheap on book-to-market, so part of the premium is the value effect in disguise.
Limitations and risks
Value/distress entanglement: much of the standalone premium is absorbed by book-to-market and distress controls.
January concentration: the effect is disproportionately a January phenomenon, raising tax-loss / microstructure concerns.
Book-leverage measurement: sensitive to how liabilities and equity (book vs market) are defined.
