We study whether a firm's name affects investor attention and firm valuation. Some Chinese firms listed on US stock exchanges have the word “China” included in their company names (“China-name stocks”), while others do not (“non-China-name stocks”). During the 2007 China stock market boom, we find that China-name stocks significantly outperform non-China-name stocks. This is not due to differences in firm characteristics, risk, or liquidity. The “China-name effect” is largely consistent with the investor attention hypothesis that price pressure caused by increased investor attention on China-name stocks during the boom period drives up China-name stocks more than non-China-name stocks.
