Every successful young investor uses the same basic setup: a Roth IRA and a brokerage account. Two accounts. That's it. Here's what each one does and what you put in each.
## Account 1: The Roth IRA
A Roth IRA is a retirement account where you pay taxes on the money before it goes in — and then never again. If you put $10,000 in a Roth IRA and it grows to $200,000 over 30 years, you pay $0 in taxes on that $190,000 gain. That's the deal.
In 2026, you can contribute up to $7,000 per year to a Roth IRA. You can open one for free at Fidelity, Schwab, or Vanguard in about 10 minutes.
What goes in your Roth IRA: ETFs and index funds. High-growth assets that you plan to hold for decades. The tax-free compounding is most powerful on your best long-term bets.
- VTI — Total US market (all 4,000+ US companies in one purchase) - QQQ — Nasdaq 100, tech-heavy growth - VGT — US technology sector ETF - SCHD — Dividend growth ETF
## Account 2: The Brokerage Account
A brokerage account is your flexible, active account. No tax benefits, but no restrictions either — deposit any amount, withdraw whenever you want. You'll pay capital gains tax when you sell for a profit, but there are no contribution limits and no penalties for early withdrawal.
What goes in your brokerage: Individual stock picks you want to watch and research actively. Companies you have high conviction in. Positions you might sell within a few years.
## What Is an ETF?
An ETF (Exchange-Traded Fund) is a basket of stocks that trades on an exchange like a single share. VTI, for example, contains a tiny slice of all 4,000+ US-listed companies in one purchase. When the US economy grows, VTI grows. You own everything — so you can't accidentally pick wrong.
ETFs charge tiny fees. VTI's expense ratio is 0.03% per year — that's $0.30 per $1,000 invested. Almost nothing.
## The Simple Rule
ETFs go in your Roth IRA. Individual stock picks go in your brokerage account. Set up automatic contributions to your Roth first ($583/month maxes out the $7,000 annual limit). Then invest whatever you can in your brokerage.
## Why This Matters
The math is unforgiving. Gen Z answers only 38% of personal finance questions correctly on average (2025 P-Fin Index). The average young investor loses approximately $948 per year by not investing — and that compounds into hundreds of thousands of dollars over a career.
The two-account system isn't complicated. It's what people who build real wealth actually do. The research, the analysis, the due diligence before each purchase — that's what Diligence is built for.
