内容摘要:
In this paper, we extend the model in Diamond and Verrecchia (1987) by incorporating the effect of price limit and argue that the removal of short-sale constraints could synergize with price limit relaxation to speed up the price discovery. Using the doubling of price limit for ChiNext board as an exogenous shock, we empirically show that the relaxation of price limit improves the price efficiency. Importantly, shortable stocks experience more improvement in price efficiency than non-shortable stocks. The further analysis documents a price reversal following the price limit hitting event, and the reversal is more profound on shortable stocks. Our findings suggest that alleviated short-sale constraints could synergize with trading restrictions relaxation to improve price efficiency.
