Abstract:

Do managers learn from stock prices? In this study, we investigate the feedback effect of stock prices on real decisions by utilizing the staggered adoption of the inevitable disclosure doctrine (IDD), which exogenously decreases the stock price informativeness of firms headquartered in states that have adopted the IDD. We show that IDD adoption decreases investment-price sensitivity, resulting in lower investment efficiency. The negative effect of IDD adoption on investment efficiency is stronger when stock prices are likely to contain less private information. Our findings are consistent with the causal effect of stock prices on real decisions.
