We investigate stock price reactions to Internet-related name changes in a market downturn. In contrast to the Internet boom period, during which there was a surge of dot.com additions, in the bust period, there is a dramatic reduction in the pace of dot.com additions accompanied by a rapid increase in dot.com name deletions. Following the Internet “crash” of mid-2000, investors react positively to name changes for firms that remove dot.com from their name. This dot.com deletion effect produces cumulative abnormal returns on the order of 64% for the 60 days surrounding the announcement day. Our results add support to a growing body of literature that documents that investors are potentially influenced by cosmetic effects and that managers rationally time corporate actions to take advantage of these biases.

ABSTRACT We examine whether mutual funds change their names to take advantage of current hot investment styles, and what effects these name changes have on inflows to the funds, and to the funds' subsequent returns. We find that the year after a fund changes its name to reflect a current hot style, the fund experiences an average cumulative abnormal flow of 28%, with no improvement in performance. The increase in flows is similar across funds whose holdings match the style implied by their new name and those whose holdings do not, suggesting that investors are irrationally influenced by cosmetic effects.
