What is Index Fund?

How does Index Fund Works?

    • Example: If Reliance makes up 10% of the Nifty 50, then 10% of the fund’s money is invested in Reliance.
  • Automatic Adjustments – When an index adds or removes stocks, the fund automatically updates its holdings to match.

  • Dividends & Reinvestment – If the companies in the index pay dividends, the fund may reinvest them or distribute them to investors.
