We investigate whether anticipation of adverse events (litigation about market timing and late trading) may trigger mutual-fund runs. We find that runs start as early as three months prior to litigation announcements. Pre-litigation runs accumulate to 31 basis points of the total net assets over a three-month window; post-litigation runs may last more than six months and accumulate to 1.25 percent over the first three-month window. Additionally, investors who run before litigation announcements earn significantly higher risk-adjusted and peer-adjusted returns than those who run after litigation. The difference in returns is particularly pronounced for funds holding illiquid assets. Finally, securities held by litigated fund families significantly underperform vis-á-vis other securities in terms of lower abnormal returns and liquidity. Our analysis suggests that a pro-rata ownership design is insufficient to prevent mutual-fund runs.
