FII and DII data: how to read the daily numbers, and what 37 sessions of it show

Every evening NSE publishes how much foreign institutional investors (FIIs, also called FPIs) and domestic institutional investors (DIIs: mutual funds, insurers, banks and pension funds) bought and sold in the cash market that day. We record it every session. Here is how to read it, and what 37 sessions of it show. The latest session, updated every evening, is at FII DII data today.

What the numbers are

• Cash market only. The figures cover shares bought and sold, not futures and options positions.
• Provisional. They are published the same evening and can be revised; the final foreign-investor figures come later from the depositories.
• Buy, sell and net. Each group's gross buying and selling in rupees crore, and the difference between them.
• When. Our copy updates between about 4 pm and 8 pm IST as the figures are published.

The latest five sessions

NIFTY change is official close to official close. Figures as recorded on 11 September 2026.

What 37 sessions show (23 July to 11 September 2026)

• DIIs bought almost every day: net buyers on 34 of 37 sessions, ₹97,043 crore in total.
• FIIs were split: net sellers on 19 sessions and buyers on 18, ₹7,895 crore net sold in total.
• They sat on opposite sides on 22 of 37 sessions, usually FIIs selling while DIIs bought.
• The net is a thin slice of the flow. Each group traded a median of about ₹29,000–30,000 crore a day in gross terms; the median FII net was ₹18 crore sold.
• The daily FII number was a poor guide to the day's direction. On the 28 sessions where we also hold NIFTY's official close (index-rebalance day left out), the sign of FII net matched NIFTY's day on 10; FII and DII together matched on 9. Against the next day's move it matched 13 of 27.
• The biggest days: FIIs sold ₹7,986 crore on 31 August, the index-rebalance day, while NIFTY fell 0.39 %. FIIs bought ₹6,688 crore on 2 September, and NIFTY still fell 0.59 %.

Thirty-seven sessions is a short window, so read these as a description of these weeks, not a rule.

Why FII selling does not have to mean the market falls

Every share sold is bought by someone. When FIIs sell and DIIs, retail or other investors absorb the shares at steady prices, the net number is large but the index barely moves. What moves price is who is in a hurry: whether buyers lift the offer or sellers hit the bid, which the day's net figure cannot show. That is read from the trades themselves, as in order flow trading.

How to get FII and DII data

NSE publishes the provisional FII/DII trading activity on its website every trading evening, and the final foreign-investor numbers are published later by the depositories. Look for the date, the category, gross buy, gross sell and net in rupees crore, and remember the figures are for the cash market only.
