Abstract of paper:

Using a novel dataset containing investors’ access of company filings through the SEC’s EDGAR system, we show that the abnormal number of IPs searching for firms’ financial statements strongly predicts future stock returns and fundamentals. A long-short portfolio based on our measure of abnormal information acquisition activity generates a monthly abnormal return of 80 basis points that is not reversed in the long run. Consistent with theories of costly information acquisition, the return predictability is stronger for firms with larger and lengthier financial filings that are more costly to process. We further show that abnormal number of IPs increases following mutual fund outflow-induced fire sale and predicts future firm profitability, earnings surprise and analyst forecast revisions. Alternative explanations including news announcements, investor recognition, price pressure, and omitted risk factors do not seem to explain our results.


Part II: 15:30-16:30

Prof. Li will introduce some popular research methods used in empirical finance.
