This paper investigates the impact of individual bank fundamental variables on stock market returns using data from a panel of 235 European banks from 1991 to 2005. The sample period marks a significant transition in the European banking sector, characterized by higher competition, lower profit margins in the traditional interest-related business and increasing non-interest income in terms of fees and commissions. In panel regressions, we relate bank stock returns to fundamental accounting information and use several corrections for the standard errors to control for heteroscedasticity, autocorrelation and spatial correlation. Our results indicate that several bank-specific variables exhibit a robust explanatory power across different model specifications. Most important, there is a positive impact of the ratio of loans to total assets, the ratio of non-interest income to total income, and the ratio of off-balance sheet items to total assets on subsequent bank stock returns. In contrast, the ratio of loan-loss-provisions to net interest revenue and the ratio of book value of equity to total assets load negatively on subsequent bank stock returns. Overall, the valuation of bank stocks incorporates both the traditional loan-related side of the banking business and the growing off-balance activities.
