The relevance of earnings and cash flows in a heavily regulated industry: Evidence from the Greek banking sector

This study examines the informational quality of annual accounting earnings within Greek banking institutions taking into consideration the most significant risks facing by such firms and specifically interest rate risk, credit risk, liquidity risk and solvency risk, alongside with the persistence of earnings and bank size as significant determinants of ERCs. Data analysis over a period of ten years (1995-2004) revealed that earnings have higher incremental importance in explaining stock return movements compared to cash flows since earnings change has been found to affect stock returns positively. Additionally, interest rate risk has a positive but not significant impact on the return-earnings relation but on the contrary solvency risk, credit risk and liquidity risk proved to have a negative impact on the valuation process for both small and big-sized banks. Finally, tests on the incremental informativeness of cash flows when earnings are transitory provide significant results suggesting that investors seek for alternative measures of banks' performance when earnings are characterized by increased extremity but inversely cash flows and earnings seem to be equally value relevant when investors evaluate big-sized banking institutions. The results are generally robust to the specification of the empirical models and the research design employed in our study.
