How did Sensex crash 2,000 points in 6 minutes while Nifty stayed stable?
Economic Times 2d ago·28 Aug 2026, 9:59 am
On Thursday, the BSE Sensex experienced a sudden and severe drop of over 2,000 points during the closing auction session. This sharp plunge occurred while the Nifty 50 index remained relatively stable, creating a notable divergence between the two benchmarks. The event was driven by extremely thin trading volumes, which amplified the impact of a few large sell orders.
This volatility has raised fresh concerns among investors regarding the new Closing Auction System (CAS). Market experts suggest that the mechanism may be struggling to ensure fair price discovery during periods of low liquidity, particularly as monthly derivatives contracts expire. The sharp moves highlight the need for caution during the final 15 minutes of trading.
Investors should pay close attention to the volume and price action during the closing auction in the coming sessions. If the divergence between Sensex and Nifty continues, it may indicate deeper liquidity issues within the market infrastructure. Monitoring the exchange's response to these anomalies will be crucial for understanding the market's stability moving forward.
