1Index is the strategy
An index fund holds the same investments as an index instead of picking them. ETF and mutual fund describe the wrapper.
2How trading differs
Mutual fund orders fill at the end-of-day price. ETF prices move all day and stay close to the value of what they hold.
3Costs
Compare the expense ratio, the yearly fee as a percent. Low-cost index options of both kinds often charge well under 0.1%.
4Which to pick
If both track the index you want at a similar cost, pick what your account makes easiest to buy automatically.

Frequently asked questions
Are ETFs better for taxes?
ETFs often pass on fewer capital gains in a taxable account. Inside a 401(k) or IRA it makes no difference.
Can I set up automatic investing?
