FII DII Data Today (18 September 2026): Foreign Investors Buy ₹600 Crore, Domestic Funds Buy ₹1,020 Crore

Institutional activity on 18 September 2026 (₹ crore)

Foreign institutional investors were net buyers to the tune of ₹600 crore in the cash segment, while domestic institutions were net buyers of ₹1,020 crore. Both sides buying on the same day is a strong flow signal and usually coincides with broad breadth.

Flow summary

• FII net: ₹599.54 Cr (18-Sep-2026)
• DII net: ₹1,019.69 Cr (18-Sep-2026)
• FII buy / sell: 38,462 / 37,862 (₹ crore)
• Advances / declines: 27 / 23

Why these flows matter

FII money is the largest swing factor in Indian equities: sustained foreign buying tends to lift index heavyweights and large-cap financials, while sustained selling pressures them regardless of domestic earnings. DII flows — mutual funds and insurers deploying SIP money — act as the counterweight and have repeatedly cushioned foreign outflows. Read the two together, over a week or a month, rather than as a single-day signal. These are provisional cash-segment figures published after the close and can be revised.

Key takeaways

• FII net: ₹+600 cr — higher at the time of writing
• DII net: ₹+1,020 cr — higher at the time of writing

About this report

Every figure on this page is read from a primary source at the timestamp shown — exchange boards for equities and indices, the exchange bid book for IPOs, published association rates for bullion, and consolidated exchange quotes for crypto — with no estimation or third-party commentary. Historical fields such as trailing returns and 52-week extremes are computed on the adjusted daily series so splits and bonuses do not create false gaps. A timestamp outside market hours reflects the last traded or last published value, not a live tick.
