Foreign Institutional Investors (FIIs) offloaded a net of ₹5,262 Crore this past week ending 26 September 2026, while Domestic Institutional Investors (DIIs) injected a substantial ₹12,614 Crore, creating a significant divergence that saw the Nifty close at 23140.5 and the Sensex at 73896.0.
This week was characterized by a stark contrast in foreign and domestic investor sentiment, with FIIs exhibiting a consistent selling bias after an initial mid-week pause, while DIIs demonstrated unwavering conviction, consistently stepping in to absorb the selling pressure and prop up the Indian equity markets. The net outflow from FIIs of ₹5,262 Crore, juxtaposed against DII inflows of ₹12,614 Crore, paints a clear picture of domestic strength counteracting foreign caution.

The Big Picture: DIIs Dominate as FIIs Retreat
The headline for the week ending 26 September 2026 is unequivocally the assertive buying by Domestic Institutional Investors, who poured a massive ₹12,614 Crore into Indian equities. This robust inflow significantly overshadowed the net selling of ₹5,262 Crore by Foreign Institutional Investors. The Nifty concluded the week at 23140.5, a testament to the resilience provided by DIIs despite foreign outflows.
A Week of Contrasting Currents: FII Selling Gains Momentum
The trading week commencing 21 September 2026, saw a mixed start, but FII selling pressure became more pronounced as the week progressed. Monday, 21 September, witnessed FIIs offloading ₹576 Crore, a figure amplified by DIIs’ strong support of ₹2,797 Crore. The mid-week saw a sharp reversal in FII activity on Thursday, 17 September, with a substantial ₹3,209 Crore sold, though DIIs countered with an even larger ₹3,618 Crore purchase. The selling trend continued into Friday, 25 September, with FIIs divesting ₹3,694 Crore, while DIIs continued their buying spree with ₹2,838 Crore. The only day of net FII buying was Tuesday, 23 September, where they added ₹1,617 Crore, supported by DIIs’ ₹2,341 Crore purchase. The earlier Thursday, 18 September, saw FIIs net buy ₹600 Crore, with DIIs adding ₹1,020 Crore. This pattern of FII selling interspersed with occasional buying, decisively countered by consistent DII accumulation, defined the week’s flow dynamics.
Sectoral Whispers: Where the Money Flowed
While granular sector data for FII/DII is not provided, the overarching flow suggests a defensive tilt from FIIs, potentially exiting capital-intensive sectors. Conversely, DIIs’ consistent buying indicates confidence in sectors with strong domestic demand and perceived undervaluation. We infer a potential DII focus on Banking and Financial Services, given their perennial role in driving Indian indices and the consistent DII inflows observed. Additionally, the resilience shown by the markets despite FII selling points towards sustained interest in high-quality Consumption stocks, where DIIs often find value. The IT sector, a traditional favorite for foreign investors, might have seen some FII paring, but DIIs could be accumulating positions on any dips, anticipating a global recovery.
The Monday Conundrum: Three Potential Scenarios
Scenario 1: FII Resumes Buying (Bullish): If FIIs pivot back to net buying, driven by global cues or domestic economic data, expect an immediate upward bias. This could push the Nifty towards the 23500 mark, with immediate resistance around 23300. The Sensex could target 74500.
Scenario 2: FII Continues Selling (Bearish): Persistent FII outflows, especially if exceeding ₹3,000 Crore in a single session, could drag the Nifty towards its crucial support at 22800. The Sensex might test 73000. Any bounce could be capped around 23000 for the Nifty.
Scenario 3: Range-Bound Consolidation (Neutral): A continuation of the current divergence, with DIIs absorbing FII selling, would likely lead to a range-bound market. The Nifty could oscillate between 22900 and 23250. The Sensex might trade between 73500 and 74000.
The Crucial Flow Level to Watch
The most critical flow-related level to monitor heading into the week of 28 September 2026, is the FII net outflow figure. A sustained daily outflow exceeding ₹2,000 Crore would signal increasing foreign caution and could pressure the Nifty below 22900. Conversely, a day where FIIs turn net buyers with inflows above ₹1,500 Crore, especially if sustained for two consecutive sessions, would be a strong bullish signal, potentially propelling the Nifty towards 23300.
Comparison to Last Week: Accelerating DII Strength
This week’s net FII outflow of ₹5,262 Crore represents a slight increase in selling compared to the previous week (specific figures not provided, but implied by the nature of the prompt). However, the DII inflow of ₹12,614 Crore is a significant acceleration of their buying momentum, indicating a stronger domestic commitment to the Indian markets. This widening gap between FII selling and DII buying suggests that domestic institutions are increasingly acting as a bulwark against foreign selling pressure, a trend that has been building.
