If you want one number that explains the last fortnight, it is this. Over the ten sessions from October 5 to 16, foreign institutional investors were net sellers of ₹39,284.79 crore in the cash market, and domestic institutions were net buyers of ₹38,126.29 crore. Our look at FII DII flows October 2026 shows the two almost cancelled out, which goes a long way to explaining why the Nifty could fall to a 21-month low and still end the fortnight higher.

| Total | -39,284.79 | +38,126.29 | -1,158.50 |
The daily figures line up with what PTI reported at the time. For example, PTI’s October 8 report cited FII selling of ₹6,121.37 crore on October 7, and CNBC-TV18 reported ₹1,708 crore of FII selling and ₹3,045 crore of DII buying on October 12.
Three things the table tells us
Foreign selling was relentless, then it eased. FIIs sold on nine of the ten days. The heaviest day, by far, was October 8, when they sold ₹12,943.58 crore, the same day the Nifty hit its 21-month low on an oil spike. The five sessions from October 5 to 9 account for ₹30,294.29 crore of the total. The next five came to ₹8,990.50 crore.
Domestic money was the shock absorber. DIIs bought on nine of the ten days, and on October 8 they put in ₹10,703.11 crore. That bucket is local institutions such as mutual funds and insurers, and the daily data doesn’t split them out.
October 16 flipped the pattern. It was the only session in the fortnight when FIIs bought and DIIs sold. One day proves nothing. We will be watching whether it turns into a trend.
On the worst day of the fortnight, foreign funds sold nearly ₹13,000 crore and domestic funds bought more than ₹10,700 crore of it back.
The bigger picture for the month
Add October 1, when FIIs sold another ₹9,484.22 crore, and Kotak Neo’s month-to-date figures show FIIs as net sellers of ₹48,769.01 crore and DIIs as net buyers of ₹48,168.13 crore. September was also heavy, with FII net selling of ₹47,143.48 crore on the same data.
Why it matters
Brent crude above $100 a barrel (PTI had it at $104.5 on October 8, and CNBC-TV18 at $106 on October 12) and an RBI that has just raised the repo rate by 25 basis points to 5.50% are not conditions that tend to bring foreign money back in a hurry. Even so, the Nifty closed October 16 at 23,146.15, up from 22,421.95 on October 1, according to NSE index data, so local buying did more than just hold the line. How the rupee and the index ended the week is in our Nifty recap for October 16, and for the fortnight as a whole, see our Dalal Street 10-session wrap.
