Using a unique dataset from Chinese stock market, we present the facts that the investors with different levels of experiences tend to time their first purchases differently when trading the IPO stocks. First, we demonstrate that experienced investors are less likely to buy IPO stocks on the first day while inexperienced investors are more likely to do so. Then we find that those investors who buy on the first non-hit day can obtain higher return relative to those investors who buy the same stock on the first day. In sum, more experienced individual investors do learn from their experiences to be more patient and observe/analyze the target stock for longer time before purchase than the green hand. Moreover, their experiences can indeed help improve the performance.
