摘要

我们利用了一个独特的实验，其中印度IPO上市的盘中价格波动被限制在一个狭窄的波段内，以检查价格波段对股票价格，投资者交易行为和股票市场流动性的影响。基于差中差估计，我们发现价格区间导致IPO股票的价格变异性显著降低。变异性的降低伴随着个人投资者在IPO后卖出的增加、交易的价格影响和IPO预期回报的增加。买卖价差保持相似。这些发现为日内价格带对股市的影响提供了新的证据。

Price bands and their effects on equity markets: Evidence from a natural experiment

We exploit a unique experiment, where the intraday price moves of Indian IPO listings are restricted within a narrow band, to examine the consequences of price bands for stock prices, investor trading behavior, and stock market liquidity. Based on difference-in-differences estimations, we find that price bands lead to a significant reduction in the price variability of IPO stocks. The decrease in variability is accompanied by increases in post-IPO selling by individual investors, the price impact of trades, and IPO expected returns. Bid-ask spreads remain similar. The findings provide new evidence on the effects of intraday price bands on equity markets.
