🧾 What is an Index Fund? 

An index fund is a mutual fund or exchange-traded fund (ETF) that passively tracks a market index (like Nifty 50 or S&P 500). It invests in the same securities as the index to replicate its performance. Benefits include low cost, diversification, and simplicity compared to actively managed funds.

📊 Types of Index Funds

Broad Market Index Funds : Large diversified indices (e.g., Nifty 50, S&P 500) : Capture overall market performance.
