How ToVest compares with traditional brokers:

Fidelity

Fidelity is a market leader for low-fee fractional US stock trading paired with top-tier research. It offers commission-free US stock and ETF trades, a robust fractional-share program that lets you invest by dollar amount, and no account minimums. Commission-free trading ensures that the broker charges no per-trade commission, which can be particularly cost-effective for small, frequent, or automated investments. Fidelity also stands out for its investor education, retirement planning tools, and strong customer service—features that make it a dependable home base for long-term savers. Its financial stability and broad suite of account types further reinforce its fit for retirement-focused investors, alongside industry-standard protections and additional excess coverage typically provided via private insurers.

Charles Schwab

Charles Schwab pairs $0 commissions on US stocks and ETFs with deep research, reliable service, and beginner-friendly design. Schwab’s Stock Slices program lets investors buy fractional shares of any S&P 500 company starting from a small dollar amount, making blue-chip diversification more accessible. There’s no account minimum, and the platform’s education, planning tools, and cash management make it a strong all-in-one choice. While options trading includes contract fees and potential regulatory/venue charges, Schwab’s comprehensive offering, investor protections (including SIPC plus excess insurance through private insurers with high aggregate limits often cited in the hundreds of millions), and broad product range suit both new and experienced investors seeking low fees without sacrificing quality.

Robinhood

Robinhood remains a go-to for mobile-first investors who want simple, fully commission-free fractional trading. The app’s clean interface, fast digital onboarding, and no account minimum make it easy to start investing small amounts immediately. Robinhood’s focus is on accessibility and ease of use; advanced research, mutual funds, and broad international stock access are limited compared to full-service brokers. For straightforward, low-friction fractional share investing—especially for beginners building habits with small, frequent buys—its zero-commission structure is hard to beat.

SoFi Invest

SoFi Invest offers a hybrid model that blends commission-free fractional stock trading with access to financial advice. New investors can choose between self-directed trading and advice-driven portfolios, all within a user-friendly mobile experience. SoFi frequently features new-user promotions, no account minimums, and extras like free access to financial planners and career resources. For those who want fractional flexibility plus a guided path to broader financial wellness—such as student loan guidance, budgeting tools, and retirement planning—SoFi is a compelling low-fee choice.

Interactive Brokers

Interactive Brokers (IBKR) is the top pick for active traders and globally minded investors who want the lowest effective execution costs, institutional-grade tools, and broad market access. IBKR supports fractional share trading that lets you invest by dollar amount, enabling precise allocation and diversification even in high-priced stocks. Expect ultra-competitive, tiered per-share pricing, advanced order types, and access to multi-asset markets worldwide from a single account, including options, futures, bonds, FX, and more. Low margin rates, pro-level research, and robust desktop and API tools make IBKR a standout for sophisticated strategies and international portfolios.

Webull

Webull combines $0 commissions, fractional share support, and a mobile-optimized platform that appeals to self-directed investors. Digital account opening is quick, paper trading is available for practice, and there’s no minimum balance to get started. The platform’s charts, alerts, and community features fit users who want low-friction access with solid tools on the go. While research depth trails full-service incumbents, Webull hits a sweet spot of usability, low fees, and around-the-clock engagement that resonates with tech-forward investors.

Public is built around fractional investing and a social, community-first experience. Investors can buy fractional US stocks and ETFs with zero commissions while exploring shared insights, community feeds, and educational content that helps newer investors learn by observing.
