What the daily flow numbers mean, their limits, and the tug of war between the two sides
Published by The Retail Trader · AUG 09, 2026 · Features
Every evening two numbers come out: how much foreign investors bought or sold, and how much domestic institutions did. This is the most followed daily data in the Indian market — and also the most over-interpreted.
FII or FPI means institutional money coming from outside — global funds, pension funds, ETFs. DII means domestic institutions — mutual funds, insurance companies, banks.
Their thinking is different. Foreign money moves on global conditions: the dollar, US rates, global risk appetite. Domestic money often moves on its own flows — such as the regular money coming in through SIPs.
A common pattern over the past several years has been that when foreign investors are selling, domestic institutions are buying, and vice versa.
So on a day of heavy FII selling the market does not fall as much as it used to. Domestic flows have given the market a cushion — but a cushion does not mean immunity.
While reading these numbers, remember this:
• These are net figures — they do not tell you what happened in which stock.
• Cash and derivatives are reported separately. Understanding the whole position from the cash number alone is wrong.
• Bulk deals, IPOs and block deals also show up in these numbers, which distorts the picture of daily flow.
• A one-day number is almost useless. Only the weekly and monthly trend tells you anything.
Many times FIIs have been net sellers and the market has still gone up. Because price is not made by the flow of one group alone — who is buying on the other side matters just as much.
So do not take flows as the cause. Take them as context: what kind of money is coming in, and what it is reacting to.
