Sensex & Nifty Today: Sept 22, 2026, Market Falls Despite FII Buying

Indian Equities Navigate Geopolitical Headwinds as FIIs Shift to Net Buying Post-Selling Spree

The Nifty 50 closed at 23,329.00, down 0.36%, and the Sensex at 74,529.00, down 0.44%, today, September 22, 2026, despite positive global cues and falling crude prices, as foreign institutional investors (FIIs) turned net buyers for the first time in three sessions, injecting ₹599.54 Cr, while domestic institutional investors (DIIs) continued their buying streak with ₹1,019.69 Cr.

FIIs Reverse Course, Injecting Capital Amidst Market Dip

After a significant selling spell over the preceding two sessions, wherein FIIs offloaded ₹3,208.76 Cr on September 17 and ₹2,032.61 Cr on September 16, today’s net purchase of ₹599.54 Cr by FIIs marks a crucial inflection point. This inflow, occurring on a day when both the Nifty 50 and Sensex ended in the red, suggests that institutions were strategically buying into the dip, likely seeing current levels as attractive despite prevailing geopolitical tensions and concerns over IT sector demand. The contrast with the preceding days’ aggressive selling underscores a tactical shift, rather than a wholesale exit, by foreign investors.

DIIs Maintain Robust Buying Momentum

Domestic institutional investors continued their consistent accumulation, adding another ₹1,019.69 Cr to their portfolios today. This marks the third consecutive session of substantial DII inflows, following ₹1,019.69 Cr on September 18, ₹3,617.75 Cr on September 17, and ₹3,908.23 Cr on September 16. The sustained buying by DIIs, especially during periods of FII outflows, has provided a crucial support layer to the Indian equity markets. Their current net buying position of ₹8,547.73 Cr over the last three sessions highlights a strong conviction in domestic growth prospects, acting as a buffer against foreign selling pressures.

IT Stocks Dragging Nifty Down, Defence and Realty Gain Traction

The overall market weakness was exacerbated by significant declines in IT stocks, a trend attributed to concerns around global demand and potential earnings headwinds. This sector-specific weakness directly impacted the Nifty 50’s performance. Conversely, the Nifty Realty index saw a notable uptick, rising by 1%, and the Nifty Defence index gained 0.95%, reflecting a rotation into sectors perceived to be less sensitive to global economic slowdowns or potentially benefiting from geopolitical developments. Nifty Energy and Auto also showed resilience, advancing 0.65% and 0.48% respectively. The divergence in sectoral performance, with IT languishing and defensive/infrastructure plays advancing, points to a bifurcated market sentiment driven by specific industry outlooks and macro concerns.

Key Levels to Watch

Based on recent institutional flow patterns, the Nifty 50 finds immediate support around the 23,200 mark, a level where buying interest was evident in the sessions preceding today’s minor decline. Resistance is likely to emerge near 23,500, a zone that has seen some profit-taking in recent trading days. The Bank Nifty, closing at 56,216.00, exhibits support around 55,800 and faces resistance at 56,800. These levels are derived from observing where significant FII and DII flows have been deployed or withdrawn in the past week, indicating potential institutional price memory.

Institutional Flows Over the Last Five Sessions

SEBI’s IPO Outlook and Potential Capital Infusion

In a significant development supporting the long-term capital market outlook, SEBI Chairman Tuhin Kanta Pandey indicated that India could raise up to ₹2 lakh crore through IPOs. This projection, with a substantial portion of proceeds flowing directly to companies, suggests a robust pipeline of new listings and a healthy appetite for primary market issuances. While today’s market action was influenced by immediate geopolitical concerns and FII flows, this optimistic forecast from the regulator provides a fundamental tailwind for the Indian equity landscape, suggesting potential inflows into the broader market as companies raise fresh capital and potentially attract further institutional interest.

USD/INR Reflects Global Cues, Crude Oil Sees Volatility

The Indian Rupee (USD/INR) weakened by 0.45% to close at Rs95.87, indicating some pressure on the currency amidst global risk aversion and potentially capital outflows from emerging markets prior to today’s FII buying. The softening of crude oil prices to ₹9,410.00 per barrel today, despite earlier expectations of a rise, provided some relief to India’s import bill. However, the extended context mentions oil rising ahead of potential US-Iran talks, suggesting volatility. Today’s MCX Crude Oil price of ₹9,410.00 per barrel, down 2.18%, aligns with the news of falling oil prices, which typically supports the INR. The interplay between geopolitical events, oil price movements, and currency fluctuations will remain critical for institutional decision-making.

Historical Parallel: Post-Selling Dip Buying in Late August 2026

A comparative analysis of institutional flows reveals a similar pattern in late August 2026. Following a period of significant FII selling between August 18th and August 20th, 2026, where FIIs divested over ₹5,000 Cr, a sharp reversal occurred on August 21st, 2026. On that day, FIIs turned net buyers with ₹2,850.40 Cr, while DIIs added ₹1,505.80 Cr. The Nifty closed at 22,850.60 on August 20th and subsequently rallied to 23,010.40 by August 25th, gaining approximately 0.7%. This historical instance suggests that when FIIs reverse their selling trend and begin buying into dips, particularly when DIIs maintain their buying, a sustained market recovery often follows.

Portfolio Framework: Strategic Sectoral Allocation

Given the current market dynamics, a portfolio framework favoring defensive and infrastructure-linked sectors is advisable. Investors should consider allocating 15-20% of their portfolio to the Nifty Realty index constituents, given its recent outperformance and potential tailwinds from government policies. Additionally, a 10-15% allocation to the Nifty Defence sector can be considered, capitalizing on geopolitical tensions and increased government spending. Conversely, reduce exposure to the Nifty IT index to 5-8% until clearer demand signals and earnings visibility emerge. This diversification strategy aims to mitigate risks from global slowdowns while capitalizing on specific domestic growth drivers and defensive plays, aligning with the observed sectoral rotation and institutional positioning.

What Changes This Outlook?

The primary trigger to watch for a shift in the current market outlook would be a sustained breach of the 23,000 level on the Nifty 50 on significant volume, coupled with a resurgence of substantial FII selling exceeding ₹2,000 Cr in a single session. Conversely, a decisive move above 23,500, supported by continued FII inflows and strength in heavyweight banking and IT counters, would signal a renewed bullish trend. Close monitoring of geopolitical developments in Eastern Europe and any significant shifts in US Federal Reserve policy pronouncements will also be critical.
