Investor Inattention and Friday Earnings Announcements

DELLAVIGNA, STEFANO, POLLET, JOSHUA M.·2009·The Journal of Finance

Abstract

Does limited attention among investors affect stock returns? We compare the response to earnings announcements on Friday, when investor inattention is more likely, to the response on other weekdays. If inattention influences stock prices, we should observe less immediate response and more drift for Friday announcements. Indeed, Friday announcements have a 15% lower immediate response and a 70% higher delayed response. A portfolio investing in differential Friday drift earns substantial abnormal returns. In addition, trading volume is 8% lower around Friday announcements. These findings support explanations of post‐earnings announcement drift based on underreaction to information caused by limited attention.

  • Investors tend to pay more attention to bad news than good news.

    “Investors tend to pay more attention to bad news than good news, which is supported by Wall Street adage that 'markets take the stairs up and the elevator down' and by index option trading where fund managers focus on hedging downside risk (e.g., Chen, Joslin, and Ni, 2019).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
