Stock-market Disruptions and Corporate Disclosure Policies

We examine managers’' disclosure decisions in response to non-fundamental price shocks. Using mutual fund fire sales as a source of market disruption, we show some firms respond by issuing earnings guidance. Others, especially firms with weaker performance and more short-term-oriented investors, engage in accrual-based earnings management. To identify the efficacy of firm disclosure choices, we examine passage of Sarbanes-Oxley and Regulation Fair Disclosure and show that they increased reliance on guidance rather than earnings management. The shift is associated with faster post-fire-sales price recovery, suggesting enhancing information disclosure rather than manipulation is effective in mitigating the effect of market disruptions.
