Abstract

This paper studies the rationale and effects of buying bots on X (former Twitter). We observe that a large amount of attention to corporate X accounts around earnings announcements is driven by bots. Bot activity is a significant predictor of investor disagreement, which is persistent in the long term. Moreover, bot activity increases analyst dispersion for the following quarterly earnings announcement. Consistent with managerial short-termism, bot activity often accompanies intense earnings management. Our results are robust to various specifications, including a matching approach indicating causal interpretation.
