What is a mutual fund?
Quick answer
A mutual fund pools money from many investors to buy a diversified mix of stocks, bonds, or other assets, managed by professionals. It lets ordinary investors own a slice of a broad portfolio without picking each investment themselves. Many people's money is combined into one professionally managed pool.
Key things to understand
- Many people's money is combined into one professionally managed pool.
- The fund buys a spread of assets, so risk is diversified across many holdings.
- You own 'units' or shares representing your portion of the whole fund.
- Returns and losses are shared among investors in proportion to what they put in.
- Funds charge fees; 'index funds' track a market and usually cost less than active ones.

What is an index fund?
A mutual fund (or ETF) that simply tracks a market index, like the S&P 500, rather than being actively managed — typically with lower fees.
Are mutual funds safe?
They reduce risk through diversification but aren't risk-free — their value rises and falls with the markets. This is general educational information, not investment advice.
How does a mutual fund work?
