Every trading day, the exchanges publish provisional figures for how much FIIs and DIIs bought and sold in the cash market.
- FII / FPI — Foreign Institutional (Portfolio) Investors: overseas funds investing in Indian markets.
- DII — Domestic Institutional Investors: Indian mutual funds, insurance companies, banks and pension funds.
Reading the numbers
Each group has a gross buy, a gross sell and a net figure (buy − sell):
- Net positive — the group bought more than it sold that day.
- Net negative — it sold more than it bought.
A common pattern in Indian markets is FIIs selling while DIIs buy. How much of the FII selling DIIs absorb is often watched as a sign of how well the market is being supported.
What the data can and cannot tell you
- It is provisional and published after the close, so it describes the day rather than causing it.
- It is net across all participants in each group, mixing many different strategies.
- One day means little. Trends over weeks and months, and the size of flows relative to normal, are more informative.
- Cash-market flows are separate from derivatives positioning, which institutions also report.
