Predicted stock issuers (PSIs) are firms with expected high-investment and low-profit profiles that earn extremely low returns. We evaluate alternative explanations for this empirical phenomenon. Our results show top-PSI firms are cash-strapped, have lottery-like payoffs, high volatility, high beta, low liquidity, and high shorting costs. Over the next 2 years, top-PSI firms earn return on assets of -30% per year, report disappointing earnings, and experience strongly negative forecast revisions. They perform poorly in down markets and are six times more likely to delist for performance-related reasons. Overall, we find substantial support for mispricing, some support for nonstandard preferences, and virtually no support for the risk explanation.
