Hedge Funds and Public Information Acquisition
研究发现，主动获取公开财务信息的对冲基金，其年化异常收益比不获取的基金高1.5%，且同一基金在获取信息的季度交易更盈利。
Hedge funds actively acquire publicly available financial disclosures. Funds acquiring such information subsequently earn 1.5% higher annualized abnormal returns than nonacquirers. Trades by the same fund in the same quarter are more profitable when accompanied by public information acquisition. Acquiring public filings is relatively less profitable when macrouncertainty is high. Funds employ a wide range of strategies for acquiring public filings. Those that systematically scrape large volumes of information, specialize in certain filing types, acquire filings with more content changes, or access information immediately outperform other funds.
