What's in a name.com?: The effects of ‘.com’ name changes on stock prices and trading activity
研究了公司宣布将名称改为包含‘.com’时投资者的反应，发现这类公告会显著提升股价和交易量，且当名称变更伴随其他战略投资时效果更强。
Abstract This paper uses a market signaling perspective to examine investor reactions to firm announcements of name changes to include ‘.com.’ Firms that change their name as a purely cosmetic technique are contrasted to those that employ other strategic investments. Results show that announcements of ‘.com’ name changes are associated with significant increases in stock prices and trading activity. Furthermore, the magnitude of investor reactions is significantly larger when name changes are accompanied by other strategies. Copyright © 2001 John Wiley & Sons, Ltd.
