Understanding the Context

How Index Fund Vs ETF Actually Works
An index fund tracks a market index—like the S&P 500—by holding the same securities in the same proportion. It’s typically structured as a mutual fund, priced once daily after market close. ETFs, or exchange-traded funds, replicate index performance using a mechanical trading mechanism that allows buying and selling throughout the day on stock exchanges. Both offer broad market exposure but differ in structure, cost, and trading flexibility.
