This paper aims at analyzing the effects of “size”, “seasonality” and “attitude to risk” on the performance Egyptian banks. This has been conducted using a sample of 10 banks, and covering the period from the first quarter2003 to the fourth quarter 2011.

Results indicate that, hypotheses regarding the significance of differences between performance indicators, according to “size”, “seasonality” and “attitude to risk” on the performance Egyptian banks could be accepted.

Also, robustness check assures the significance of these effects, where indicators of both capital adequacy and earnings are affected by both of size and attitude to risk, while asset quality is affected by size and seasonality.
