In-Depth Breakdown: Fidelity Investments vs M1 Finance (Automated Pie Investing)

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 M1 Finance (Automated Pie Investing) Works

M1 Finance bridges the gap between a self-directed brokerage (like Fidelity) and an automated robo-advisor (like Wealthfront). Instead of placing manual buy orders for 15 different ETFs and dividend stocks every payday, you design a custom portfolio "Pie" with target percentage weights (e.g., 60% VTI, 20% VXUS, 10% SCHD, 10% AAPL). Every time cash hits your account—or dividends are paid—M1’s dynamic rebalancing engine automatically buys fractional shares of whichever slices have drifted below their target weight.
