Introduction: Why Institutional Money Matters

The impact of FII and DII on Market Volatility becomes visible during events such as global crises, interest rate changes, or major economic disclosures.

Who Are FIIs?
Foreign Institutional Investors are large investment entities based outside India that invest in Indian financial markets. These include hedge funds, foreign mutual funds, pension funds, sovereign wealth funds and global banks.

Who Are DIIs?
Domestic Institutional Investors: Domestic Institutional Investors are institutions within India itself. They consist of Indian Mutual Funds, Insurance Companies, Banks, EPFO, and Pension Funds.

In recent years, strong SIP inflows have made DIIs a powerful stabilising force. In market corrections, purchases made by DIIs can help alleviate volatility and function as a support factor for the market structure during that phase.
What is Market Volatility?
