TLDR
Market Recap: December 30, 2025
On December 30, Thin year-end, monthly expiry trade kept benchmarks flat: Sensex 84,675.08 (-20, -0.02%) and Nifty 50 25,938.85 (-3.25, -0.01%). Broader risk cooled with Nifty Midcap 100 -0.15% and Nifty Smallcap 100 -0.28%, while leadership rotated into metals, PSU banks, and autos as IT and defensives lagged. Volatility eased, with the India VIX at 9.61 (-1.13%), as FIIs were net sellers (in cash) and the rupee strengthened due to rebalancing flows.
Key Drivers :
Expiry-day positioning: Month-end squaring kept the tape range-bound, with hedges and rolls dominating flows and keeping directional conviction low.
FII-DII push-pull: Foreign selling persisted, but domestic buying absorbed supply, limiting downside in frontline indices despite weak market breadth.
Cyclicals take the wheel: Metals and select financials outperformed on rotation, offsetting drag from IT and consumption names in a low-volume session.
