We study a sample of Form 13F filings where fund advisors seek confidential treatment for some or all of their 13(f)-reportable positions. Consistent with the hypothesis that managers seek confidentiality to protect proprietary information, we find that confidential positions earn positive and significant abnormal returns over the post-filing confidential period. We also find that managers are more likely to seek confidential treatment of illiquid positions that are more susceptible to front-running. Overall, our analysis highlights important benefits of reduced disclosure that are relevant to the current policy debate on hedge fund transparency.

We examine the extent to which investment opportunities and/or mispricing motivate equity issuance and contribute to post-issue stock underperformance. We decompose market-to-book ratios into misvaluation and growth option components and find that issuing firms are both overvalued and have greater growth opportunities relative to nonissuers. Firms with greater growth opportunities invest more in capital expenditures and research and development (R&D) after issuance but do not experience lower post-issue stock returns. In contrast, issuing firms with greater mispricing tend to decrease long-term debt and/or increase cash holdings and do earn lower returns. Our findings are consistent with behavioral explanations for post-issue stock price underperformance.
