Bankex put sees a dramatic surge of 14,700% on expiry day
Economic Times 2d ago·28 Aug 2026, 1:02 am
Bankex options saw an extraordinary spike in trading volume on Thursday's expiry, with put option premiums surging by over 14,700%. This rapid price escalation occurred within minutes, catching many traders off guard and triggering significant market reaction. The surge in put buying was so intense that it briefly distorted the market's view of the day's performance, creating a sharp divergence between the Bankex and broader indices like the Nifty.
This dramatic move highlights the high volatility and concentrated activity often seen during option expiry days. While the broader market indices closed lower, the Bankex's steep decline was more pronounced than the Nifty's, driven by this specific options activity. For investors, this event underscores the importance of understanding the mechanics of derivatives and the potential for sudden, short-term price distortions in the market.
Moving forward, traders will closely watch the Bankex's momentum to see if this volatility persists or if the market stabilizes. The focus will be on whether the sharp drop was a one-off event driven by expiry mechanics or the start of a broader downtrend for the banking sector. Investors should exercise caution and avoid making impulsive decisions based on such short-term, high-volatility spikes.
