Each broker on this page has been chosen for their support of fractional shares, allowing investors to purchase as little as 0.001 of one full stock. Quality in fractional share brokers is defined by real-time execution at the same market price as whole shares, transparent order routing with no hidden spreads on stock trades, and low minimum investment amounts of $1 or less per transaction. This feature best suits investors who want diversified portfolios without large cash commitments, but you should note that some brokers only offer fractional trading on US-listed stocks and may restrict limit orders to whole shares.
Interactive Brokers offers unrivalled market access and the lowest commissions in the industry for active stock traders. The TWS platform is extremely powerful but has a steep learning curve for beginners.
Fidelity's zero-expense-ratio index funds, commission-free trading, and Active Trader Pro platform make it the most compelling long-term investing home for US investors who want institutional fund management alongside serious trading capability, all under one roof with no account minimum.
Charles Schwab combined the scale and financial stability of a century-old brokerage with TD Ameritrade's thinkorswim platform, giving US investors commission-free trading alongside institutional-grade analytical tools that no standalone fintech broker has replicated.
What this means
