The Sensex F&O prediction for tomorrow on 21 May 2026 covers the BSE Sensex derivatives market on the day before the Sensex weekly options series expires on Thursday 22 May. With the Sensex closing at 75,318.39 on Wednesday after an intraday recovery session, the Sensex F&O prediction for tomorrow for Tuesday 21 May is the pre-expiry positioning session where option writers defend their strikes and theta decay is accelerating sharply. Unlike the NSE Nifty 50 weekly expiry which falls on Tuesday, BSE Sensex weekly options expire on Thursday, making Tuesday the second-to-last full-liquidity session for the current Sensex weekly series.<\/p>

Kunal Singla, Associate Director at Univest, notes that the Sensex F&O prediction for tomorrow is additionally complex because 21 May is simultaneously the Nifty 50 and Bank Nifty weekly expiry day on NSE, meaning the broader market will experience significant Nifty-driven volatility on Tuesday that will directly spill over into Sensex derivatives. Ankit Jaiswal adds that the Sensex F&O prediction for tomorrow requires traders to account for this cross-index expiry dynamics when managing Sensex options positions.<\/p>
