An Empirical Investigation of Short-Selling Activity Prior to Seasoned Equity Offerings
实证研究了增发前卖空活动的特征及其与发行折价的关系，并评估了SEC规则10b-21对抑制卖空和降低折价的效果。
We investigate the nature and magnitude of short-selling activity around seasoned equity offerings, the relation between short-selling activity and issue discounts, and the consequences of the Securities and Exchange Commission (SEC's) adoption of Rule 10b-21 in response to concerns about manipulative short-selling practices. Seasoned offerings are characterized by abnormally high levels of short selling and option open interest. Higher levels of such activity are related to lower expected proceeds from the issuance of new shares. Where it could not be circumvented, Rule 10b-21 appears to have curbed short-selling activity and reduced issue discounts.
