Price Informativeness and Investment Sensitivity to Stock Price
The article shows that two measures of the amount of private information in stock price — price nonsynchronicity and probability of informed trading (PIN) — have a strong positive effect on the sensitivity of corporate investment to stock price. Moreover, the effect is robust to the inclusion of controls for managerial information and for other information-related variables. The results suggest that firm managers learn from the private information in stock price about their own firms’ fundamentals and incorporate this information in the corporate investment decisions.
