Cross-sectional determinants of post-IPO stock performance: evidence from China

This paper examines the cross-sectional determinants of post-IPO long-term stock returns in China. We document that the aftermarket P/E ratio has the most robust negative association with post-IPO stock returns. The negative relation indicates that the market corrects the aftermarket overvaluation of IPO firms in the long run. Underwriter reputation has a positive effect on post-IPO stock returns, while board size has a negative impact, consistent with the views that reputable underwriters mitigate the information asymmetry in IPO pricing and over-sized boards reduce the effectiveness of corporate governance. However, we find little evidence indicating that the equity ownership structure is significantly associated with post-IPO stock returns.

Conglomerate structure and capital market timing

We examine the effects of keiretsu structure on capital market-timing. Keiretsu groups offer a hybrid structure between fully integrated conglomerates and stand-alone firms. We find that past market conditions affect the capital structure of keiretsu firms more than they affect the capital structure of unaffiliated firms. The decision to issue equity is more correlated with market conditions for keiretsu members than it is for unaffiliated firms. The stock returns of keiretsu firms following the issuance of equity decrease with the size of the issuance. These results suggest that keiretsu members time the issuance of equity more so than stand-alone firms.

Ownership concentration, foreign shareholding, audit quality, and stock price synchronicity : evidence from China

This paper investigates the effects of largest-shareholder ownership concentration, foreign ownership, and audit quality on the amount of firm-specific information incorporated into share prices, as measured by stock price synchronicity, of Chinese-listed firms over the 1996–2003 period. We show that synchronicity is a concave function of ownership by the largest shareholder with its maximum at an approximate 50% level. Further, we find that synchronicity is higher when the largest shareholder is government related. We also find that foreign ownership and auditor quality are inversely associated with synchronicity. Finally, we show that the amount of earnings information reflected in stock returns is lower for firms with high synchronicity.
