2.20What are FIIs and DIIs?

1What is it?

FIIs (Foreign Institutional Investors, now officially FPIs, Foreign Portfolio Investors) are foreign funds investing in India. DIIs (Domestic Institutional Investors) are Indian institutions like mutual funds and LIC.

2Why does it exist?

Their daily net buying or selling is published by the exchanges and watched closely. Heavy FII selling often pushes markets down. DIIs, supported by monthly SIP inflows, often buy when FIIs sell.

3Stock market example

A news line might read: "FIIs net sold ₹3,000 crore; DIIs net bought ₹3,500 crore." That means foreign funds sold more than they bought, and Indian funds absorbed it.
