In-Depth Breakdown: Fidelity Investments vs Vanguard

1. How Fidelity Investments Works

Fidelity is arguably the best consumer brokerage in the US today. Unlike competitors that pay 0% on uninvested cash, Fidelity automatically sweeps your cash into SPAXX (a core money market fund) earning around 5.0%. They do not use Payment for Order Flow (PFOF) for equity trades, ensuring you get excellent price execution.

2. How Vanguard Works

Founded by index fund pioneer John Bogle, Vanguard is client-owned — meaning the funds are owned by their shareholders, keeping expense ratios at absolute rock bottom (0.03% on VOO/VTI). Vanguard is the definitive choice for long-term buy-and-hold retirement investors funding traditional IRAs, Roth IRAs, and Solo 401(k) accounts.
