• Index Options: FIIs engaged in substantial net buying worth +₹12,360.54 crore, driven largely by intense positioning in Nifty options (+₹15,476.45 crore), offset by net sales in Bank Nifty options (-₹2,046.40 crore) and Midcap Nifty options (-₹1,228.55 crore).

Key Drivers and Outlook

The contrasting dynamic between lower index closes and aggressive institutional buying indicates structural support beneath the surface. Domestic liquidity continues to act as a resilient anchor, with mutual funds and domestic pension pools deploying sustained SIP and asset-allocation inflows. While foreign institutional investors have maintained an intermittent stance in recent sessions, their net positive turn in both cash and single-stock derivatives points to selective accumulation in large-cap counters.

Going forward, traders will closely watch the 22,500–22,550 support band on the Nifty 50. The sharp uptick in India VIX suggests that index participants are bracing for wider trading swings in the upcoming week, where derivative positioning roll-overs and global cues are likely to dictate short-term directional conviction.
