Which broker is best for new stock investors?

For first-time stock investors, Fidelity and Charles Schwab stand out. Both have zero trading commissions, no account minimums, excellent educational resources, and strong customer support. Fidelity's mobile app and fractional share investing (starting at $1) make it especially accessible. Schwab's branch network appeals to those who prefer in-person help. Both are far better starting points than platforms designed for active traders.
