FII/DII activity: what the daily data means (2026)
FII/DII activity is the daily scoreboard of how India's two biggest classes of institutional investors traded. FIIs are foreign investors and DIIs are domestic institutions, and the daily figure shows how much each group bought and sold, and which way the net flow went. It is one of the most watched numbers in the Indian market, and also one of the most misread.
Definition
FII/DII activity
is the daily net buying or selling by foreign portfolio investors (FIIs) and domestic institutions (DIIs) in the Indian cash market. The exchanges publish a provisional net figure after each close, showing which group added money and which pulled it out that day. Source: NSE and BSE.
Who are FIIs and DIIs?
FIIs are foreign portfolio investors: overseas funds, pensions, and asset managers that buy Indian listed securities. SEBI folded the old FII label into the broader FPI (Foreign Portfolio Investor) framework in 2014, so FII and FPI now point to the same group even though daily reports still use FII.
DIIs are domestic institutions: Indian mutual funds, insurance companies, banks, and pension or provident funds. They are the home-grown counterweight, and on many days when FIIs sell, DIIs buy, or the reverse.
Where the daily number comes from
After the market closes, the NSE and BSE release provisional net figures for FII and DII activity in the cash segment. Provisional is the key word: the number can be revised, and the final, more detailed picture comes from the depositories and SEBI a little later. Most of the "FII sold X crore today" headlines quote the provisional cash-market figure.
Net = gross buys minus gross sells

How to read FII/DII activity without over-reading it
The daily number is easy to find and easy to misuse. A few guardrails.
- One day is noise. Net flows swing with expiry, index rebalances, and large one-off trades. The multi-week trend carries more signal than a single session.
- Provisional is not final. Early figures get revised, so note whether you are reading the provisional or final number.
- Cash is not the whole story. The headline figure usually covers the cash segment, not derivatives, so it is a partial view of institutional positioning.
- Pair it with context. FII flows read differently against a rising rupee than a falling one.
Flock tracks daily FII and DII activity from the exchange disclosures, dated and linked to the source, so you can follow the trend rather than react to a single day. What it means for your own decisions is your call to make.
Frequently asked questions
What does FII/DII activity mean?
It is the net buying or selling by two groups of large investors on a given day. FIIs (foreign portfolio investors) and DIIs (domestic institutions like mutual funds and insurers) report their gross buys and sells, and the net figure shows which way the big money leaned. Source: NSE and BSE.
Where does the daily FII/DII data come from?
The NSE and BSE publish provisional net cash-market figures for FIIs and DIIs after the close each trading day. More detailed and final figures come from the depositories and SEBI. The provisional number is what most daily reports quote. Source: NSE, BSE, SEBI.
What is the difference between FII and FPI?
They refer to the same kind of investor. SEBI merged the older FII category into the broader Foreign Portfolio Investor (FPI) framework in 2014. Most daily data still uses the label FII, but the official term is FPI. Source: SEBI.
Is a single day of FII selling meaningful?
On its own, rarely. One day's net figure is noisy and often provisional. The trend over weeks, read alongside index moves and currency, carries more information than any single session. It is data, not a recommendation. Source: NSE and BSE.
