Yeah, the shift of NSE expiries to Tuesday is definitely a welcome move for most traders.

But I also feel it would’ve been cleaner if all expiries across instruments and exchanges were just parked on Monday. That way, you get one dedicated day to deal with all the expiry-related adjustments and volatility, and the rest of the week can run more on natural demand-supply without expiry drama hanging over every other session.

Mondays are usually slow anyway, with the first half just waiting for global cues before the real activity starts. If expiries were fixed for that day, it would give expiry-related positions a proper window, and then the remaining days would allow price discovery in a much healthier way. Kind of adds more rhythm and clarity for both speculators and long-term investors.

That said, derivatives as a segment really need to be watched. The way volumes have grown, it often feels like speculation overtakes genuine hedging. Short-dated options especially create unnecessary noise and can distort cash market moves. Curtailing or at least rationalizing derivatives — whether via margins, expiries, or contract structures — would make the market more stable and protect retail participants from getting carried away. In the end, derivatives should aid risk management, not turn into the main attraction.
