When a long weekend pushes the market to close on Friday and reopen on Tuesday, traders suddenly face a Nifty expiry with no days to adjust their positions. This new situation is being called the "zero‑buffer trap".
What Changed?
SEBI moved the Nifty expiry day to Tuesdays starting in 2025. Previously, if a Monday was a holiday, traders still had Tuesday and Wednesday to tweak their portfolios before the Thursday expiry. Now, a Friday close followed by a Tuesday expiry leaves no buffer days.
Why It Matters
The lack of a buffer means any open positions must be settled immediately on the expiry day. This can lead to sudden price swings, higher volatility, and unexpected losses for those who cannot react in time.
How Traders Can Prepare
- Plan Ahead: Identify potential expiry dates that fall after a long weekend and review positions early.
- Use Stops: Set stop‑loss orders before the market closes on Friday to limit downside risk.
- Reduce Exposure: Consider scaling down large positions ahead of the weekend.
- Stay Informed: Keep an eye on the holiday calendar and expiry schedule.
Bottom Line
The shift to Tuesday expiries creates a tighter timeline for traders during long weekends. By planning early and using risk‑management tools, investors can avoid the surprise losses that the zero‑buffer trap can bring.
