What the option chain shows
GIFT Nifty is trading at +0.23% (+55.3 points) in the pre-market window, signaling a measured start to the week after Friday's close posted a gain of 24.11 points (+0.10%) for Nifty. Sensex showed notably sharper momentum on Friday, closing 360.97 points higher (+0.47%), setting a different tenor for the two indices as they head into a compressed expiry week.
India VIX sits at 10.68, reflecting subdued volatility ahead of the open. With just one day remaining until Nifty expiry and three days for Sensex, option positioning is already tightening. Both indices carry meaningful OI support levels—Nifty at 23,000 and Sensex at 75,000—where fresh Addition activity was logged, suggesting buyers have been establishing fresh protection or building positions near these floors. Resistance-side OI tells a different story: Nifty's 24,000 level shows Unwinding, implying long positions have been trimmed, while Sensex resistance at 77,000 continues to see Addition, pointing to continued defensive buildup higher up.
Bias and readiness
The 5-day average daily move runs 143 points for Nifty and 515 points for Sensex. Against this backdrop, Nifty's chart support lies at 23,860.45 with resistance at 23,970.35—a tight band of roughly 110 points that leaves little room for directional conviction at the open. Sensex has wider breathing room, with support at 76,392.86 and resistance at 76,760.57, a 368-point range that aligns with its larger point swings.
Friday's session saw Sensex outpace Nifty in both relative and absolute terms. Whether that momentum bleeds into Monday or whether the modest GIFT Nifty gap reflects consolidation ahead of rapid expiry unwinds will depend on how the open trades into the day's first few minutes. Option expiry weeks typically see sharper repricing around structural OI levels, and the interplay between fresh support-side Addition and resistance-side divergence between the two indices warrants close monitoring as cash markets commence.
