The intraday volatility effects of price-limit hits for stocks in the BIST-50
index during a volatile period are examined. Our evidence supports the volatility
no-effect, dampening and spillover hypotheses depending on whether the lower or
upper price limit is hit and on when the hit begins and ends. Post-hit
volatilities tend to be lower for limit hits near the beginning of the first
trading session, unchanged for those that transcend a trading session and for
upper price-limit hits near the end of either trading session, and higher for
lower price-limit hits near the end of either trading session. These results are
robust using samples differentiated by cross-listed status, same-day news,
equi-distant and trade-by-trade returns and volatility measures accounting for
return-series autocorrelations. Our findings have implications for emerging
markets planning to impose price-limit bands or to increase their efficacy.
