Against the backdrop of an increasing threat of misinformation on social media, several countries have enacted regulations to curb the spread of misinformation. This study examines how corporate social media strategy responds to misinformation regulations. Using a large cross-country dataset of corporate tweets and a stacked regression analysis, we show that misinformation regulations lead to less corporate social media disclosure. This result suggests that, by deterring misinformation, these regulations reduce firms’ need to use social media to counteract its adverse effects. Additional analyses show that the effect strengthens among countries with higher social media usage and those with stronger investor protection but weakens for firms with stronger information environments. Finally, we provide direct evidence that firms post fewer tweets refuting misinformation about themselves following the enactment of these regulations.

Securities litigation risk is a well‐recognized yet underexplored source of financial reporting complexity or unreadability. This study examines the effect of litigation risk on the readability of corporate financial reports. The 1999 Silicon Graphics Inc. (SGI) court ruling unexpectedly reduced litigation risk for firms within the Ninth Circuit Court's jurisdiction. Using a difference‐in‐differences design centered on the SGI court ruling, we find that, while the readability of financial reports generally declines over the sample period, treated firms in the Ninth Circuit experience a comparatively smaller decline in readability than control firms in other states after the ruling. Put differently, treated firms experience a relative improvement in reporting readability following the ruling. This effect is concentrated among firms prone to securities litigation and those with greater external financing needs, but it is muted for firms engaging in earnings management. Furthermore, improved reporting readability among treated firms can be partially attributed to alleviated concerns about the adequacy of cautionary language, as evidenced by a significant decrease in negative forward‐looking statements, particularly risk‐related ones. Collectively, our findings suggest that securities litigation risk contributes to reduced readability in financial reporting.

Product market advertising, while containing little new information, triggers spikes in investor attention. Using weekly advertising data, we find that sell‐side analysts issue optimistic earnings forecasts in response to heavier advertising in the prior week. This effect is not driven by confounding earnings or product news. It is more pronounced for experienced analysts and analysts affiliated with brokerages that rely solely on trading revenues. The optimistic forecast bias intensifies the impact of advertising on investor trades of the underlying stock during the following week, especially on retail buying. Overall, analysts appear to issue optimistic forecasts to exploit retail investor attention spikes induced by advertising.
