DIIs Step Up with ₹5,101 Cr Infusion as FII Selling Drags Nifty Below 24,300

Market Snapshot

The Indian equity benchmarks started the week on a cautious note, extending losses for the second consecutive session. The BSE Sensex declined by 281.09 points, or 0.36%, to settle at 77,728.16. Similarly, the NSE Nifty 50 slipped below the psychological 24,300 mark, ending 78.35 points or 0.32% lower at 24,287.65. While the headline indices struggled, the broader market showed resilience, with the Nifty Midcap 100 and Smallcap 100 indices gaining 0.05% and 0.36%, respectively.

Institutional Flows: Cash Market

Institutional activity on August 17, 2026, revealed a stark contrast between foreign and domestic sentiment. Foreign Institutional Investors (FIIs) turned aggressive sellers, reversing their previous buying trend, while Domestic Institutional Investors (DIIs) significantly ramped up their purchases to absorb the supply.

• FIIs were net sellers in the cash segment, offloading equities worth ₹2,535.10 crore.
• DIIs emerged as the primary support for the market, recording a massive net purchase of ₹5,101.46 crore.
• The combined net institutional flow for the day stood at a positive ₹2,566.36 crore, as DII buying more than doubled the FII sell-off.

Derivatives Market Activity

The derivatives segment indicated a mix of caution and consolidation. The Nifty Put-Call Ratio (PCR) stood at 0.98, suggesting a balanced sentiment between bulls and bears, though slightly leaning toward the cautious side.

• India VIX, often referred to as the "fear gauge," dropped slightly by 0.99% to settle at 11.30, indicating a lack of immediate panic despite the index decline.
• Options data for the upcoming sessions showed the highest Open Interest (OI) concentration at the 25,000 Call and 23,000 Put strikes.
• Max Pain for the near-term expiry was identified at the 24,400 level, serving as a key pivot point for traders.

Key Drivers and Outlook

The primary drag on the market was the IT sector, with the Nifty IT index tumbling nearly 2%. Concerns regarding global technology spending and muted demand outlook weighed heavily on sector leaders. Conversely, commodity-linked stocks and the realty sector provided a silver lining.

• Sectoral Performance: IT and Pharma were the biggest laggards, with HCL Tech (-2.57%), Infosys (-2.51%), and Sun Pharma (-2.49%) leading the declines. On the flip side, Metal and Realty sectors outperformed, gaining 1.26% and 1.46% respectively, led by Hindalco (+1.98%) and Tata Steel (+1.36%).
• Corporate News: Reliance Industries recovered from early lows to end 1% higher, providing late-session support to the Nifty. L&T also remained in focus after its offshore unit bagged a mega order worth ₹15,000 crore in West Asia.
• Outlook: Analysts suggest that the market is currently in a "buy on dips" mode supported by DII liquidity, but FII outflows remain a headwind. Investors are closely monitoring global cues, particularly US-Iran tensions and Brent crude prices, which are hovering near $89 per barrel, for further direction.
