Top 7 Nifty 50 Options Strategies Ranked by 5-Year Historical Win Rate

1. The New Era of Indian Derivatives: SEBI's 2024–2026 Framework

Single Weekly Index Expiry, Lot Size 65, and the 2% ELM Surcharge

The landscape of Indian equity derivatives underwent a generational regulatory transformation under SEBI circular SEBI/HO/MRD-PoD2/CIR/P/2024/00181 and NSE circular NSE/FAOP/70616. To curb retail gambling in zero-day options, regulatory authorities restructured weekly contracts, margin rules, and contract specifications across the National Stock Exchange (NSE).

Under the updated framework, Nifty 50 stands as the sole NSE benchmark offering weekly index options (with weekly expiries consolidated on Tuesdays). Simultaneously, contract lot sizes were recalibrated: after temporarily expanding to 75, the official Nifty 50 market lot size was revised to 65 starting in January 2026, anchoring notional contract values firmly between ₹15 lakh and ₹20 lakh.

Most critically for option sellers, SEBI instituted an additional 2% Extreme Loss Margin (ELM) surcharge levied on all short option positions on expiry days. At a Nifty index level of 24,500 with lot size 65, this 2% surcharge demands an additional ₹31,850 in margin per naked sold lot (2% * 24,500 * 65). This capital penalty has rendered naive naked straddles and strangles obsolete, making defined-risk, hedged multi-leg structures the mandatory choice for quantitative survival.
