Abstract: Abstract of the thesis entitled Accounting and Stock Performance of Initial Public Offerings and Seasoned Equity Offerings: Evidence in China Submitted By OUYANG Liangyi For the Degree of Doctor of Philosophy at the University of Hong Kong in August 2004 Although it has a short history, the China stock market developed very fast in the past decade. Stock is now a primary investment instrument for Chinese. This research studies the long-term accounting and stock performance of initial public offerings and seasoned equity offerings in China. We find that operating performance of initial public offerings and seasoned equity offerings in China experience substantial deterioration in the post-issue period. Issuers typically have significant higher earnings and sales revenue than their industry peers before year 0. However, their advantages shrink to nothing in a short period. Extraordinarily high current accruals are reported in year 0, which consist of a large discretionary component after broken down by a Jones (1991) model. We attribute the unusual changes in accruals and operating performance to be a result of earnings management. Moreover, we find that both absolute and discretionary current accruals in year 0 are powerful in predicting changes of income and cash flow in the following three years. This finding further strengthens the hypothesis that managers dress up their earnings to meet the earnings threshold by recording aggressive accruals, which cause earnings reverse in the aftermarket period. Investors are surprised at the poor earnings. Earnings announcement effects, measured by 3-, 9- and 21-day market-adjusted abnormal returns are significantly negative in post-issue period. We also find stock offerings have negative buy-and-hold abnormal ii returns in a three-year window. Both IPOs and SEOs have around 30% less returns than size-matched non-issuers. However, when the matching standard changes to be size and book-to-market ratio, the abnormal returns are reduced by half and not significant for SEOs. We also apply the Fama and French (1993) model to monthly trading data of issuers. The result shows that the time-weighted abnormal return is not significant. We consider this difference to be a result of the time-clustering and cyclical pattern of stock issues in China. Due to high volumes of stock issues in periods of high past returns and low volumes in periods of low past returns, a time-weighted method may not find underperformance while an equal-weighted method may. We explain the negative cross-sectional abnormal returns as results of investor overoptimism and information asymmetry. Investors have insufficient information about issuers and overestimate issuers' future earnings. Along with new information released in earnings reports, they gradually downgrade their valuation, thus contributing to the negative cross-sectional returns. We find that the three-year buy-and-hold abnormal returns on issuers are significantly correlated with changes in net income during the same period, which is also supportive of the investor overoptimism hypothesis. This research contributes to the literature by providing new evidence from China, a major emerging economy with high growth. We suggest that earnings management could be stimulated by explicit earnings requirement and exacerbated by inve
