This study provides a comparative analysis of the long-run investment performance of founder and non-founder CEO led IPO firms in high and low technology environments. We find weak evidence of superior long-run investment performance on the part of founder CEO led IPO firms, since the significance of the results are sensitive to choice of benchmark, portfolio weighting method, and factor regression model. However, in the context of high technology IPO firms, we find consistent evidence to indicate that founder CEO led firms provide significantly higher long-run returns relative to non-founder CEO led firms. Our results suggest that the unique nature of founder CEO leadership is particularly beneficial to IPO firms in high technology environments.
