What is FII and DII? FII stands for foreign institutional investor and DII stands for domestic institutional investor. They are the large organisations, such as foreign funds on one side and Indian mutual funds or insurers on the other, whose buying and selling shows up in the daily market reports. This guide explains who they are, how they differ and how to read their numbers. See our FII and DII data page for the figures.
Key Takeaways
- FII means foreign institutional investor. DII means domestic institutional investor.
- Since 2014, foreign institutions register with SEBI as foreign portfolio investors (FPIs), but the exchange reports still use the label FII/FPI.
- DIIs include Indian mutual funds, insurers, banks and pension funds. Retail investors are not counted as DIIs.
- Daily reports show buy value, sell value and net value for each group. Net means buy minus sell.
- The figures describe what happened. They do not predict what the market will do next.

What Is FII and DII? The Short Answer
An institutional investor is an organisation that invests a large pool of other people’s money. A pension fund, an insurance company and a mutual fund are all examples. When that organisation is based outside India, the market calls it an FII. When it is based in India, the market calls it a DII.
These two groups matter because they trade in very large amounts. A single day of heavy buying or selling by either group can be visible in the daily numbers. That is why news channels quote “FII selling” and “DII buying” almost every evening. Learning the terms once helps you read those headlines with more care.
Why people keep asking what is FII and DII
Most new investors first meet the terms in a market wrap such as “FIIs sold shares worth a certain amount while DIIs bought”. The words sound technical, yet the idea is simple. One group is foreign money, the other is domestic money, and the daily report tells you which side was the net buyer. Our page on the difference between FII and DII goes deeper into the comparison.
FII Full Form and Who Counts as an FII
FII is the short form of foreign institutional investor. It describes a large foreign organisation that buys and sells shares, bonds or other securities in Indian markets. Typical examples are overseas pension funds, sovereign wealth funds, insurance companies and global asset managers. If you want concrete cases, see our list of FII examples in India.
FII, FPI and the 2014 change
You will also see the term FPI, which stands for foreign portfolio investor. SEBI notified the SEBI (Foreign Portfolio Investors) Regulations, 2014 on 7 January 2014, and foreign investors now register under the FPI framework. In everyday talk, FII and FPI are often used for the same group. The exchange reports follow this habit and label the data “FII/FPI”.
SEBI later issued new FPI regulations in 2019. Its operational guidelines for FPIs describe two registration categories, Category I and Category II. Category I covers government related entities and appropriately regulated entities such as banks, asset management companies and insurers. Category II covers the rest, for example unregulated funds, individuals, family offices and corporates. The guidelines also say that older Category III FPIs were deemed to be Category II.
The same guidelines say that the combined holding of FPIs belonging to the same investor group should stay below 10 percent of the paid-up capital of a company. Limits and rules can change, so check the official site before relying on any figure. You can also read how foreign ownership shows up in company filings in our guide to the FII shareholding pattern.
DII Full Form and Who Counts as a DII
DII is the short form of domestic institutional investor. It describes an organisation set up in India that invests in Indian securities. Mutual funds, insurance companies, banks and pension funds are the usual examples. Each is overseen by its own regulator, for instance SEBI for mutual funds and IRDAI for insurers.
The money behind a DII mostly comes from Indian savers. When you invest in a mutual fund through a monthly plan, your money goes to a fund house, and the fund house buys shares on your behalf. In the daily report, that buying is counted as DII activity, not as retail activity. An individual who buys shares directly is not a DII.
For a closer look at how domestic institutions appear in the daily figures, read our explainer on DII data.
FII and DII Compared at a Glance
The table below puts the two groups side by side so the main differences are easy to see.
| Point | FII | DII |
|---|---|---|
| Full form | Foreign institutional investor | Domestic institutional investor |
| Based in | Outside India | India |
| Examples | Overseas pension funds, sovereign funds, global asset managers | Indian mutual funds, insurers, banks, pension funds |
| Registration | As an FPI with SEBI, in Category I or II | With their own sector regulator, for example SEBI or IRDAI |
| Source of money | Foreign investors and savers | Mostly Indian savers |
| Report label | FII/FPI | DII |
One more difference is behaviour. Foreign investors react to global events such as interest rate moves abroad or currency changes, while domestic institutions react to local savings flows. That does not mean one group is always right. It only means their reasons for trading can differ.
Where to Find FII and DII Data
The National Stock Exchange publishes a free FII/FPI and DII trading activity report. The page offers CSV downloads for the capital market segment: one for NSE alone and one that combines NSE, BSE and MSEI. The page itself does not state a publishing time, so the timing of each update can vary. Check the official site for the current schedule and format.
If you prefer a simple summary, our FII DII data today page lays out the daily cash market figures. These are end-of-day numbers released after the market closes, so they are not a streaming feed.
How to Read FII and DII Numbers
Each daily report gives three values for every group: the gross buy value, the gross sell value and the net value. Amounts are usually shown in rupees crore, where one crore is ten million. Read them in this order.
- Gross buy is the total value of shares the group bought that day.
- Gross sell is the total value of shares the group sold that day.
- Net is gross buy minus gross sell. A positive net means the group bought more than it sold. A negative net means it sold more than it bought.
What is FII and DII net flow?
Net flow is the single number most people quote. If the FII net is minus 1,700 crore, foreign institutions sold 1,700 crore more than they bought on that day. Because the net value hides the gross turnover, it helps to glance at both. Two days with the same net can have very different gross values, and the gross value tells you how busy the session was.
Reading FII and DII net flow over a longer window
One day rarely tells a full story. Add the net values for a week or a month and compare them with earlier periods. A run of several negative days looks different from a single large one. Our FII data explainer shows how to track such a run without over-reading any single day.
Common Mistakes With FII and DII Data
- Treating one day as a trend. A single large net figure can come from a block trade, an index rebalancing or a one-off event.
- Assuming FII selling always means a falling market. Domestic buying can offset it, and prices depend on many other factors.
- Mixing up cash and derivatives. The daily FII/DII report covers the cash market. Futures and options positions sit in separate reports.
- Calling the data “live”. The figures are released after the close and may be provisional, so treat them as an end-of-day record.
- Counting yourself as a DII. Your direct trades are retail activity. Only institutions are counted in the DII column.
Worked Example: FII and DII Net Flow Step by Step
The numbers below are made up to show the method. They are not real market data. Suppose that on Day 1 the report shows FIIs buying 9,500 crore and selling 11,200 crore, while DIIs bought 10,800 crore and sold 8,900 crore. On Day 2, suppose FIIs bought 12,000 crore and sold 10,500 crore, while DIIs bought 9,200 crore and sold 9,900 crore.
- Day 1 FII net: 9,500 minus 11,200 = minus 1,700 crore.
- Day 1 DII net: 10,800 minus 8,900 = plus 1,900 crore.
- Day 1 combined net: minus 1,700 plus 1,900 = plus 200 crore.
- Day 1 FII gross turnover: 9,500 plus 11,200 = 20,700 crore. The FII net is about minus 8.2 percent of that turnover (1,700 divided by 20,700, rounded).
- Day 2 FII net: 12,000 minus 10,500 = plus 1,500 crore.
- Day 2 DII net: 9,200 minus 9,900 = minus 700 crore.
- Day 2 combined net: plus 1,500 minus 700 = plus 800 crore.
What this tells you: in the example, FIIs were net sellers on Day 1 and DIIs absorbed the selling. On Day 2 the roles switched. The data describes who was buying and who was selling. It does not say why, and it does not forecast the next session.
| Measure (Rs crore) | Day 1 | Day 2 |
|---|---|---|
| FII buy | 9,500 | 12,000 |
| FII sell | 11,200 | 10,500 |
| FII net | -1,700 | +1,500 |
| DII buy | 10,800 | 9,200 |
| DII sell | 8,900 | 9,900 |
| DII net | +1,900 | -700 |
| Combined net | +200 | +800 |
Pros and Cons of Tracking FII and DII Data
| Pros | Cons |
|---|---|
| Free and published by the exchange | Shows what happened, not why it happened |
| Splits foreign and domestic institutional activity clearly | Single-day figures can be distorted by block trades or rebalancing |
| Easy to turn into a simple net number | Released after the close, so it lags the market |
| Helps you read market news with more context | Covers cash market activity only, not derivatives positions |
| Useful for spotting multi-week buying or selling streaks | Does not predict future prices |
FAQ
What is FII and DII in simple words?
FII means foreign institutional investor, such as an overseas pension fund. DII means domestic institutional investor, such as an Indian mutual fund or insurer. Both are large organisations that invest pooled money.
What is FII and DII data and where can I see it?
It is the daily record of buy, sell and net values for each group. The NSE publishes it as a free FII/FPI and DII trading activity report. Check the official site for the current schedule.
Is FII the same as FPI?
In daily talk the two terms are used for the same group. Foreign investors register with SEBI as FPIs under rules that started in 2014, and the exchange reports label the data FII/FPI.
Are retail investors counted as DII?
No. DII means institutions such as mutual funds, insurers, banks and pension funds. Your own direct trades count as retail activity, although your mutual fund units fund DII buying.
Does FII selling always push the market down?
No. Domestic buying can offset foreign selling, and prices depend on many other factors. Use the numbers as context, not as a signal to buy or sell.
The Bottom Line
So, what is FII and DII? FIIs are foreign institutions that invest in Indian markets, usually registered as FPIs, and DIIs are Indian institutions such as mutual funds, insurers, banks and pension funds. The daily report shows how much each group bought, sold and netted, and it is a useful record of who was active in the market.
Read gross and net figures together, look at weeks rather than single days, and remember that the data explains what happened, not what will happen. Your next step is to open the NSE report once and match its columns with the steps above. More explainers are on our blog.
