FII/DII Weekly Scorecard: September 23, 2026 — Bears dominate as FIIs sell aggressively

This week, Foreign Institutional Investors (FIIs) offloaded a staggering ₹8,196 Cr worth of Indian equities, while Domestic Institutional Investors (DIIs) injected a robust ₹14,029 Cr, creating a significant divergence as the Nifty closed at 23450.2 and the Sensex at 74807.0.

The Week That Was: DIIs Defend Against FII Exodus

The trading week ending September 23, 2026, was defined by a dramatic outflow from Foreign Institutional Investors (FIIs), who divested a net of ₹8,196 Cr from Indian equities. This aggressive selling by overseas investors was, however, met with equally aggressive buying from Domestic Institutional Investors (DIIs), who poured in a substantial ₹14,029 Cr. This stark dichotomy between foreign and domestic sentiment underscores a pivotal moment for Indian markets, with DIIs acting as a critical buffer against FII selling pressure. The Nifty ended the week at 23450.2, reflecting the tug-of-war between these two major investor classes.

FIIs Retreat Sharply, DIIs Step In With Force

The narrative of the week was unequivocally set by FIIs’ aggressive selling. Monday, September 21, saw a significant outflow of ₹576 Cr from FIIs, immediately countered by DIIs injecting ₹2,797 Cr. However, the real capitulation from foreign investors began mid-week. Wednesday, September 17, witnessed a staggering net sale of ₹3,209 Cr by FIIs, a figure that dominated the session’s flow dynamics. This was preceded by a substantial sell-off on Tuesday, September 16, with FIIs offloading ₹2,033 Cr. Monday, September 15, continued this trend with FIIs selling ₹2,978 Cr. Amidst this foreign selling spree, DIIs demonstrated remarkable resilience and conviction, consistently buying across all five sessions. Their net purchases reached a weekly high on Wednesday, September 17, with an inflow of ₹3,618 Cr, followed closely by ₹3,908 Cr on Tuesday, September 16, and ₹2,686 Cr on Monday, September 15. This DII support prevented a sharper decline in the indices, with the Nifty managing to hold above the 23450 mark.

Sectoral Currents: DIIs Favoring Financials and Industrials

While granular sector-specific data for FII and DII flows is not available for this week’s aggregated report, the sheer magnitude of DII inflows strongly suggests a strategic accumulation in sectors perceived as defensive and growth-oriented. Given DIIs’ mandate often involves long-term wealth creation for Indian citizens, their consistent buying in a week of FII outflows likely concentrated on the financial services sector, which forms a significant portion of DII portfolios and benefits from domestic economic growth. Additionally, their strong buying could have extended to capital goods and infrastructure-related companies, anticipating government spending and a rebound in domestic manufacturing. Conversely, FII selling pressure might have been more pronounced in sectors with higher foreign participation or those sensitive to global economic slowdown fears, potentially including IT services and select consumer discretionary stocks.

The Divergence Dilemma: A Precursor to Volatility?

The pronounced divergence between FII selling and DII buying this week, with a net difference of ₹22,225 Cr (₹14,029 Cr DII inflow minus ₹8,196 Cr FII outflow), is a critical signal. Historically, such wide gaps in institutional flows often precede periods of heightened market volatility. When foreign investors are aggressively exiting, it can signal concerns about global economic headwinds, geopolitical risks, or India-specific regulatory changes that are not yet apparent to domestic investors. DIIs, on the other hand, often have a longer-term view and may be capitalizing on perceived undervaluation created by FII selling. This week’s pattern suggests that while FII sentiment has turned cautious, DIIs are betting on India’s domestic growth story. This ongoing standoff means that any shift in FII sentiment, or a continuation of their selling, could lead to significant price action, while sustained DII buying could provide a floor.

Monday’s Scenarios: Navigating the Week Ahead

The institutional flow dynamics of the past week present three distinct scenarios for the upcoming trading week, with the Nifty currently hovering around 23450:

• Scenario 1: FIIs Resume Buying (Bullish Tilt): If FIIs reverse their selling trend and begin to accumulate, even at a modest pace of ₹500-₹1,000 Cr per day, it could trigger a strong rally. The Nifty could then target immediate resistance at 23800, with a decisive breach potentially pushing it towards 24200. This scenario would be supported by positive global cues or favorable domestic economic data.
• Scenario 2: FIIs Continue Selling (Bearish Pressure): Should FII selling persist at levels seen earlier this week (₹1,000-₹2,000 Cr daily), DII buying may struggle to fully absorb the outflows. The Nifty could break below its current support at 23200, with the next significant downside target at 22800. This would indicate that FII concerns are outweighing DII conviction.
• Scenario 3: Standoff Continues (Range-Bound Consolidation): The most likely scenario, given the established trend, is a continuation of the FII selling and DII buying standoff. This could lead to a period of consolidation, with the Nifty trading within a defined range. The upper bound would likely be capped around 23600, while the lower bound could be tested near 23100. Volatility within this range might still be elevated as intraday sentiment shifts.

The Single Most Important Level to Watch

For the week commencing September 28, 2026, the most critical level to monitor for the Nifty will be the 23100 mark. This level represents a confluence of the current trading range’s lower boundary and a psychological support. A sustained breach below 23100, especially on significant FII selling volume, would signal a breakdown in DII support and could trigger accelerated downside momentum. Conversely, holding above 23100, coupled with any sign of FII capitulation or DII accumulation exceeding ₹2,000 Cr in a single session, would suggest resilience and the potential for a bounce back towards the 23600-23800 levels.

Flow Dynamics Compared to Last Week

The previous week (ending September 18, 2026) saw FIIs as net buyers of approximately ₹1,700 Cr and DIIs as net buyers of around ₹5,000 Cr. This week’s data starkly contrasts with that trend. The pivot from FII buying to aggressive selling, coupled with a significant increase in DII buying from ₹5,000 Cr to ₹14,029 Cr, indicates a dramatic shift in foreign investor sentiment. The acceleration of FII outflows and the corresponding surge in DII inflows signal a heightened level of market tension and a clear divergence in opinion between global and domestic institutional players. This intensification of opposing flows suggests that the market is at a critical juncture, moving from a period of moderate foreign interest to one of significant foreign caution.

Key Levels to Watch

Nifty Support: The immediate support for the Nifty stands at 23100, followed by 22800. A decisive move below 23100, driven by persistent FII selling, could open the door for a test of 22800. Given the current DII buying strength, a fall below 22800 would require a significant escalation of foreign outflows or a major negative catalyst.

Nifty Resistance: Immediate resistance is observed at 23600. A break above this level, supported by a shift in FII sentiment or sustained DII buying exceeding ₹3,000 Cr in a day, could propel the Nifty towards 23800. Further upside targets would be contingent on broader market sentiment and FII return.
