Previous studies report mixed evidence on how financial leverage affects expected stock returns. Our theoretical and empirical results suggest that these inconclusive findings are driven by differences in firms’ debt maturity structures and refinancing needs. In our model, the firm optimizes its capital structure by jointly choosing leverage and the mix of short- and long-term debt, which determines the firm’s debt refinancing intensity. Since shareholders commit to cover potential shortfalls from debt rollover, they require a return that increases in, both, leverage and debt refinancing intensity. Our empirical results confirm this model prediction and show that firms with higher (lower) leverage earn higher (lower) stock returns when controlling for the immediacy of debt refinancing. The return differential of high-leverage firms relative to low-leverage firms increases with refinancing intensity and, as also predicted by the model, is directly linked to the value premium. Accounting for differences in firms’ debt maturity profiles also provides new insights for the distress puzzle.
