    Twitter Investor Sentiment and Corporate Earnings Announcements

    European Financial Management, 2023, 29 (3), pp. 953-986

    We examine the impact of firm‐specific investor sentiment (FSIS) on stock returns for negative and positive earnings surprises. Using a measure constructed from firm‐specific tweets, we find that FSIS has a greater impact on stock returns for negative relative to positive earnings surprises. We further show that the impact of FSIS is greater for firms whose valuation is uncertain and difficult to arbitrage. Moreover, we provide evidence of return reversals over post‐announcement periods. Our results highlight the importance of FSIS around earnings announcements.
