Frequently Asked Questions
What is an ETF?
An exchange-traded fund is a basket of stocks, bonds, or other assets that trades on an exchange like a single stock. ETFs offer instant diversification, typically lower fees than mutual funds, and tax efficiency through their in-kind creation/redemption mechanism.
How do I pick an ETF?
Start with your goal (broad market, sector exposure, income, international), then filter by expense ratio (lower is better for long-term), fund size/liquidity, tracking error, and tax treatment. Our AI-scored MoonshotScore on each ETF page helps compare quality across factors.
Are ETFs better than mutual funds?
Generally yes for taxable accounts — ETFs trade intraday, usually have lower expense ratios, and are more tax-efficient. Mutual funds still win for dollar-cost averaging via automatic investment plans and some 401(k) plans.
