**1. M1 Finance: The Best for Passive Investors**
**Why M1?**
M1 Finance is a robo-advisor designed for passive investors who want hands-off ETF investing. It’s particularly strong for:
- Young professionals (ages 25-40) with limited time to manage investments.
- Tech workers in high-cost areas (e.g., SF, NYC) who need low fees.
- Those who prefer automation over active trading.
**Key Features & Costs**
- Automated ETF portfolio (no manual trading required).
- Low fees: 0.25% AUM fee (vs. 0.65% at Fidelity).
- No minimum deposit (unlike Fidelity’s $0 minimum but $500+ for fractional shares).
- 2026 ROI Projection: If you invest $10K at 7% annualized returns, M1 could grow to $17,900 in 10 years (vs. $17,500 at Fidelity).
**When to Avoid M1**
- If you want individual stock picking (M1 is ETF-only).
- If you need tax-loss harvesting (M1 doesn’t offer this).

**Why Fidelity?**
Fidelity has been the gold standard for decades, and in 2026, it remains the best for:

**Key Features & Costs**

**Why IBKR?**

**Key Features & Costs**

- Advanced tools: Algorithmic trading, margin trading, futures.
- 2026 ROI Projection: If you trade actively, you could outperform M1/Fidelity, but this depends on skill.
