In China the number 8 is considered 'lucky' and the number 4 'unlucky'. This paper shows that almost twenty percent of the IPO prices for the Chinese domestic market (A-shares) end in the 'lucky' number 8 as compared to a little more than three percent ending in the 'unlucky’ number 4 (a ratio of almost six to one). It also documents that 'lucky' number combinations make up the ending two digits of more than ten percent of A-share price endings. This occurrence is far greater than expected by chance or by other theories that have explained price clustering in financial markets. We conclude that issuers of Chinese IPOs consciously choose to favour 'lucky' numbers when setting prices.

We study whether firm name has an effect on firm valuation. Some Chinese firms listed on U.S. stock exchanges have the word "China" or "Chinese" included in their company names ("China-name stocks"), whereas others do not ("non-China-name stocks"). During the China stock market boom in 2007, we find that China-name stocks significantly outperform non-China-name stocks. This is not due to differences in firm characteristics, risk, or liquidity. We also find a significant increase in both abnormal returns and trading volumes of existing China-name stocks to the listing events of new Chinese initial public offerings. This "China-name effect" is largely consistent with the hypothesis that optimistic investor sentiment during the China stock market boom drives up China-name stocks more than non-China-name stocks.

This paper examines the role of earnings management in the underpricing and long-term performance of Chinese initial public offerings (IPOs) issued during the 1998-2003 period. It tests the earnings extrapolation hypothesis that naive investors extrapolate pre-issue earnings without fully adjusting for potential manipulation of accounting accruals, thereby inflating the initial trading price. If the hypothesis holds, underpricing will be positively related to initial earnings management. However, since the latter is subsequently corrected over time, it will lead to inferior long-term stock performance. The empirical evidence is consistent with both the earnings extrapolation and the long run underperformance hypotheses for our sample of 506 IPOs.
