Why Is Expiry-Day Volatility Raising Concerns Over Closing Auction System: Manjiri Mazumdar
NDTV Profit 2d ago·28 Aug 2026, 10:17 am
Expiry-day volatility is raising fresh concerns about the closing auction system used by Indian stock exchanges. During this process, which determines the final price for the day, trading volume often drops sharply. This sudden drop in liquidity can lead to significant price swings, sometimes causing the closing price to differ substantially from the market's true sentiment. The system is designed to ensure orderly trading, but these extreme movements suggest it may not be effectively capturing the true value of stocks.
This issue matters to investors because the closing price is a critical benchmark. It is used for calculating portfolio gains, setting margin requirements, and determining the settlement value for derivatives. If the auction mechanism fails to reflect fair value, it can distort these key financial metrics. Market participants are now watching to see if regulators will adjust the rules to improve price discovery and prevent artificial volatility during the final trading minutes.
