How to Choose the Best ETF Investing App for You
Consider Your Investing Style
If you prefer hands-on control and research, Fidelity or Charles Schwab are ideal. If you want set-it-and-forget-it automation, M1 Finance excels. For traditional buy-and-hold investing with the lowest costs, Vanguard remains unbeatable.
Look at Expense Ratios
The difference between a 0.05% and 0.50% expense ratio might seem small, but over 30 years on a $100,000 investment, it can cost you $30,000+ in wealth. Fidelity's zero-expense-ratio funds are hard to beat.
Start Small
All five platforms allow you to start with $1 or less. There's no need to wait for a large sum—begin immediately with dollar-cost averaging to build discipline and compound returns.
Evaluate Research Tools
Charles Schwab and Fidelity offer superior research, screeners, and educational content. If you plan to research individual ETFs before buying, these platforms provide better tools.
