Description
Summary:We examine short-sellers’ use of textual information in annual reports for shorting activities. We find that more uncertainty and negative words in annual reports are associated with greater abnormal shorting volume. Short selling motivated by textual information negatively predicts stock price reaction around the filing date of 10-K reports. We further provide some evidence that textual information used by short-sellers are related to revisions of analysts’ earnings forecasts, changes in firm fundamentals, and increasing crash risk subsequently. Our results suggest that textual information in annual reports forms an important part of short-sellers’ information advantage.
