    Abstract: We examine the long-run stock performance of IPO firms subsequent to lockup expiration,
    when insiders are allowed to release their shares, from the perspectives of two alternative
    hypotheses. The first hypothesis, the “informative selling hypothesis,” predicts that insider
    sales, particularly sales by senior corporate insiders, will convey unfavorable signals to
    investors, and that IPO firms with aggressive post-lockup insider sales can thus be expected
    to exhibit poor long-run performance following lockup expiration. The second hypothesis,
    “the diversification hypothesis,” notes that corporate insiders may simply desire to
    diversify their portfolios or meet their liquidity needs, and that insiders may therefore sell
    their shares when they are allowed to do so without conveying material information by their
    action. Accordingly, this hypothesis predicts that insider selling does not necessarily have
    predictive power for the subsequent long-run performance of IPO stocks following lockup
    expiration. We find that IPO firms with aggressive insider selling after lockup expiration,
    particularly selling by high-ranking corporate insiders, exhibit poor long-run stock returns.
    The findings are consistent with the informative selling hypothesis
