FII / DII Data Today — Institutional Flows

What is FII / DII data?

FII/DII data reports how much two classes of large institution bought and sold in the market on a given day. FIIs — Foreign Institutional Investors — are overseas funds investing in Indian equities; DIIs — Domestic Institutional Investors — are Indian mutual funds, insurers and pension funds. The headline figure is the net: total buys minus total sells. A positive net means the group was a net buyer that day; a negative net means it was a net seller. Figures are shown for the cash (equity) segment and, for FIIs, the F&O (derivatives) segment. NSE and BSE compile the numbers from daily filings by FII/DII custodians: the cash-market figure is typically released provisionally around 5:00 PM IST and finalized by roughly 6:00 PM IST the same evening, while the FII derivatives (participant-wise open interest) breakdown follows around 7:00 PM IST — so the early evening number can see minor revisions.

How to read this list

FIIs and DIIs move the largest pools of capital in the market, so the balance between them is a powerful read on who is driving price. The most useful lens is the tug-of-war: Indian markets frequently see FIIs selling while DIIs — funded by steady monthly SIP inflows — step in to absorb it, which can keep the index range-bound even on heavy foreign outflows. Read the trend across several sessions rather than reacting to one day, and use the sector breakdown below to see exactly where foreign money is being deployed or pulled.

• Are FIIs and DIIs on the same side today, or offsetting each other?
• Is today part of a multi-session trend, or a one-day blip?
• Which sectors are FIIs adding to or exiting (see the breakdown below)?
• Does the FII F&O position confirm or contradict their cash-segment stance?
• Is the figure still today's provisional print or the finalized number released the next day?

What to watch for

A single day of FII/DII flow is mostly noise — the trend over weeks is what matters, and reacting to one red or green print is a classic mistake. The cash-segment net also does not capture the full picture: FIIs can be net sellers in cash while positioning bullishly in derivatives, so read the two together. Figures can also differ slightly between trackers depending on whether they show NSE's cash-segment number alone or a combined NSE+BSE+MSEI total — treat a small discrepancy between two sources as a reporting-scope difference, not an error. Finally, flows explain market direction, they do not predict it — heavy DII buying does not guarantee the index rises the next day.

Frequently asked

What is FII and DII data?

FII (Foreign Institutional Investor) and DII (Domestic Institutional Investor) data shows how much these large institutions bought and sold in the market. The net figure — buys minus sells — indicates whether they were net buyers or net sellers that day.

Why do FII and DII flows matter?

FIIs and DIIs move the largest amounts of capital, so their combined activity strongly influences index direction. Sustained FII selling can pressure the market, while steady DII buying — funded by domestic SIP inflows — often cushions it.

What time is FII DII data released?

The cash-market net figure is usually available as a provisional number around 5:00 PM IST and finalized by about 6:00 PM IST the same day. The FII F&O (derivatives) position follows in the participant-wise open-interest report released around 7:00 PM IST.

What does it mean when FIIs sell and DIIs buy?

It means foreign funds are pulling money out while domestic institutions are stepping in to absorb it. This tug-of-war is common in India and often keeps the index range-bound even on days of heavy foreign outflows.
