FII DII Data 01 SEP 2025
Institutional Investors’ Activity in the Stock Market (01 September 2025)
The Indian stock market on Monday witnessed a sharp contrast in the trading activity of institutional investors. According to the data, Domestic Institutional Investors (DIIs) emerged as strong buyers. They purchased shares worth ₹13,314.23 crore and sold shares worth ₹8,969.30 crore, resulting in a net inflow of ₹4,344.93 crore into the market.
On the other hand, Foreign Institutional Investors (FIIs/FPIs) remained on the selling side. They bought equities worth ₹9,540.36 crore but offloaded shares worth ₹10,970.07 crore, leading to a net outflow of ₹1,429.71 crore.
Market experts believe that while FIIs continue to stay cautious due to global uncertainties and the strengthening dollar, strong domestic participation is providing solid support. This heavy DII inflow helped absorb the selling pressure and ensured that the Indian benchmarks ended the session in the green.

1. What is FII? (Foreign Institutional Investors)
- FIIs are foreign institutions like mutual funds, hedge funds, insurance companies, and pension funds that invest in the Indian stock market.
- Their inflows bring bullish momentum (markets rise), and their outflows create bearish pressure (markets fall).
Example: If a US-based fund like Vanguard or BlackRock invests in Reliance or Infosys shares, that’s FII activity.
2. What is DII? (Domestic Institutional Investors)
- DIIs are Indian institutions such as mutual funds, insurance companies (like LIC), banks, and pension funds.
- Their participation often supports the market, especially when FIIs are selling.
Example: If LIC or HDFC Mutual Fund buys Indian company shares, that counts as DII investment.
