DIIs Pump ₹11,272 Crore to Absorb Heavy FII Selling as Nifty and Sensex Settle Lower for Third Straight Session

Market Snapshot

Dalal Street witnessed another volatile trading session on Wednesday, September 30, 2026, with the headline benchmarks giving up sharp midday gains to end lower for the third straight day. Early momentum faded into the close as persistent geopolitical jitters, elevated U.S. Treasury yields, and firm crude prices prompted late-session profit taking.

• BSE Sensex: Slipped 48.78 points, or 0.07%, to finish at 72,480.29, after surging over 530 points to an intraday peak of 73,062.23.
• NSE Nifty 50: Settled 95.75 points, or 0.42%, lower at 22,620.45, closing near the lower band of its daily range.
• Broader Indices: Outperformed large caps with resilient risk appetite in small and mid-sized counters; the Nifty Midcap 100 closed flat to slightly positive (+0.02%), while the Nifty Smallcap gained 0.27%.
• Sectoral Performers: Nifty Private Bank, Nifty Realty, and Nifty Media managed gains, whereas Nifty Healthcare, Nifty Pharma, Nifty Consumer Durables, and Nifty Metal faced intense selling pressure. Top individual laggards included Apollo Hospitals, Max Healthcare, and Sun Pharma, while Kotak Mahindra Bank and ICICI Bank provided critical support.

Institutional Flows: Cash Market

The tug-of-war between foreign outflows and domestic liquidity reached a fever pitch during Wednesday's session, resulting in a net institutional balance in positive territory:

• Foreign Institutional Investors (FIIs): Offloaded Indian equities on a massive scale, recording a net provisional outflow of ₹10,148.41 crore in the cash segment.
• Domestic Institutional Investors (DIIs): Stepped in aggressively as the counterweight, recording net purchases worth ₹11,271.73 crore.
• Net Institutional Flow: Stood at +₹1,123.32 crore, as relentless retail-backed mutual fund inflows and pension allocations completely absorbed foreign selling.

This marks an intensifying trend over the past week; cumulative weekly FII sales crossed ₹25,480 crore, while DIIs absorbed over ₹23,410 crore to keep market drawdowns orderly.

Derivatives Market Activity

Positioning across the futures and options (F&O) space highlights a defensive and cautious stance among market participants:

• Index Futures Positioning: FIIs continue to hold an overwhelmingly short-heavy book in index futures, with their index-futures long-short ratio hovering near a depressed level of 0.09, reflecting extreme hedging and directional pessimism.
• Options Open Interest (OI): Call Open Interest heavily dominated Put OI, with overall Call OI at roughly 17.11 crore contracts against Put OI of 10.96 crore contracts.
• Key Strikes: Substantial Call writing was concentrated across the 22,700–23,000 strikes, with the 23,000 strike holding the highest Call open interest to create a formidable resistance ceiling.
• Market Gauges: India VIX rose to 13.52, while the overall Put-Call Ratio (PCR) hovered near 0.65, confirming that traders remain reluctant to carry aggressive upside risk overnight.

Key Drivers and Outlook

The Indian equity market continues to grapple with a complex convergence of macro headwinds:

• Surging Global Yields: Elevated U.S. 10-year Treasury yields hovering above 5.25% continue to draw capital away from emerging markets, sustaining downward pressure on foreign portfolio allocations.
• Geopolitical & Energy Pressures: Brent crude held firm near $103 per barrel amid stalled negotiations and supply friction in the Middle East, reigniting imported inflation worries for the Indian economy.
• Forex Market: The Indian rupee showed slight intraday resilience, gaining 13 paise to close at 95.81 against the U.S. dollar, supported by central bank intervention.
• Technical Outlook: Chartists note that the Nifty 50 has reached a critical inflection zone around its weekly moving averages near 22,600–22,550. A decisive breakdown below 22,500 could expose the benchmark to the 22,300–22,200 support corridor. Conversely, a sharp short-covering rebound will require the index to reclaim the immediate supply ceiling at 22,800.
