ABSTRACT We examine how short sellers affect long‐run management forecasts using a natural experiment (Regulation SHO) that relaxes short‐selling constraints on a group of randomly selected firms (referred to as pilot firms). We find that compared to other firms, the pilot firms issue more long‐run good news forecasts but do not change the frequency of long‐run bad news forecasts. The increase in good news forecasts is greater when the pilot firms have higher‐quality forecasts, greater uncertainty about firm value, or higher manager equity incentives. Overall, these results and the results of additional analyses indicate that the reduction in short‐selling constraints and the increase in short‐selling threat induce managers to enhance disclosures through more long‐run good news forecasts to discourage short sellers.

ABSTRACT: Managers have great discretion in determining forecast characteristics, but little is known about how managerial incentives affect these characteristics. This paper examines whether managers strategically choose forecast precision for self-serving purposes. Building on the prior finding that the market reaction to vague forecasts is weaker than its reaction to precise forecasts, we find that for management forecasts disclosed before insider sales, more positive (negative) news forecasts are more (less) precise than other management forecasts. The opposite applies to management forecasts disclosed before insider purchases. These results are consistent with managers strategically choosing forecast precision to increase stock prices before insider sales and to decrease stock prices before insider purchases. Additional analyses indicate that the impact of managerial incentives on forecast precision is less pronounced when institutional ownership is high or when disclosure risk is high, and is more pronounced when investors have difficulty in assessing the precision of managers' information.
