Abstract
We focus on stocks without shorting activities and quantify their tightness of short-sale constraints from the demand side. Using the special institutional setting of the Chinese securities market, we estimate a characteristics model to explain the actual short-selling turnover of shortable stocks. We then apply the model out-of-sample to unshortable stocks and estimate their shorting demand, which is entirely suppressed by regulation and positively measures the tightness of short-sale constraints. We find that the suppressed shorting demand contains rich information as it negatively predicts future returns, adds to price delays, and leads to a stronger post-earnings-announcement-drift.
