Investing & Dividends Mostly accurate, with one big caveat

Professor G’s 16% portfolio: what his 2026 “big changes” video leaves out

Verdict: Mostly accurate, with one big caveat. The strategy is genuinely sound, but the 16% return figure is a product of an exceptional 15-year stretch — not a rate you should pencil into your own retirement math.

Nolan Gouveia — “Professor G” on his channel Investing Simplified — opens his latest video by walking through his entire portfolio and reporting a 31–33% gain over the last 12 months and a 16% average annual return over 15 years. Then he lays out the “big changes” he’s making for the back half of 2026. Most of the video is refreshingly grounded: low-cost index funds, dollar-cost averaging, no day-trading heroics. The caveat isn’t that he’s lying. It’s that one number is doing more work than he lets on.

What the video actually claims

The pitch, if you can call it that, is restraint. Gouveia says his portfolio is roughly 7% cash, 25% real estate equity, 18% in a 401k/403b, 9% Roth IRA, 9% crypto, and 32% in a taxable brokerage. The brokerage is 80% ETFs, 20% individual stocks — anchored by SCHD, VOO, QQQM, SCHG, and a value tilt into VTV and Berkshire Hathaway.

He’s blunt about what doesn’t work. Citing FINRA data, he notes that only 13% of day traders stay consistently profitable over six months and just 1% over five years, while 72% end the year in the red. His whole framing is a contrast: slow, boring, tax-aware investing versus screen-watching churn.

Then comes the headline. “On average over the last 15 years, my portfolio has gotten an average of 16% growth per year.” He drives it home with a compounding example: $100,000 at 8% for 15 years grows to $317,216, while the same amount at 16% becomes $926,552. “Huge difference,” he says. He’s not wrong about the arithmetic.

Does 16% a year hold up?

Here’s where a reporter has to slow the tape. The math is fine — run the numbers and 16% compounded for 15 years really does roughly quadruple your money relative to 8%. The question isn’t the calculator. It’s the input.

The S&P 500’s long-run average annual return since its 1957 launch is about 10%, according to Fidelity. But the specific window Gouveia is describing — roughly 2010 through 2025 — was one of the strongest bull runs in modern history. Fidelity’s own figures put the 10-year return through December 2025 at 14.8% and the 5-year at 14.4%, versus 10.4% over 30 years. A growth-tilted portfolio during that stretch beating 16% isn’t extraordinary. It’s what that particular decade-and-a-half handed almost everyone who stayed invested in U.S. equities.

So the 16% is probably real. It’s just not repeatable on demand.

Why does this matter? Because the compounding table he shows uses 16% as if it’s a durable baseline, and a beginner watching that chart could reasonably walk away expecting nine-times returns over 15 years. Swap in the S&P’s historical 10% and $100,000 becomes about $418,000 — still excellent, but less than half the $926,552 on screen. The gap between 10% and 16% is the difference between a plan and a hope. Nobody knows which the next 15 years will deliver.

The fine print on his own accounts

Two smaller details deserve a flag. First, Gouveia says the Roth IRA limit is “about $7,500.” For 2025 the IRS caps annual contributions at $7,000 for anyone under 50, rising to $8,000 at 50 and older. Small miss, but it’s the kind of number viewers copy directly.

Second, his tax discussion of SCHD is genuinely useful and rarely mentioned by other creators. He explains that in California he pays the 15% federal long-term capital gains rate, plus the 3.8% net investment income tax, plus state tax on dividends that California treats as ordinary income — pushing his effective rate on that fund above 30%. That’s why he’s shifting new taxable-account money from SCHD toward VTV and Berkshire, which throw off little or no dividend. It’s a real, location-specific reason, and he’s careful to say “do your own research based on your own state.” (If you’re in Texas or Florida with no state income tax, this entire calculus changes — a point worth remembering when any U.S. creator talks taxes.)

What the method actually requires

Strip away the portfolio tour and the underlying method is almost aggressively simple: buy broad index ETFs, dollar-cost average every month, hold for 15-plus years, don’t panic. That’s it. It doesn’t require the “hundreds of hours of research” he mentions spending on Bitcoin. It requires a brokerage account, an automatic transfer, and the emotional discipline to keep buying when the market — as he himself puts it — “feels like we’re all being propped up on this house of cards.”

The unspoken requirement is time and consistency, not skill. His own FINRA citation is the tell: the reason boring investing wins is precisely that the exciting version fails for more than 70% of day traders, per state securities regulators quoted by the SEC. The SEC’s own investor guidance warns that day traders “typically suffer severe financial losses in their first months of trading.” Gouveia’s strategy works because it refuses to play that game.

There’s also a soft monetization layer worth naming. The video repeatedly points to a link where you can book a paid one-on-one “portfolio review” with him over Zoom. He’s clear that he isn’t a financial advisor and won’t take a percentage of your assets. That’s an honest disclaimer — but be aware that paid, individualized advice about buying and selling securities is the exact activity the Investment Advisers Act of 1940 regulates. A general education call is one thing; specific “here’s what to buy” guidance for a fee is another. Know which one you’re paying for.

Who actually wins this game

The people who win with Gouveia’s approach are the ones who never touch it after setup. Consistent contributors who let 15 years of compounding run. He’s a case in point — a professor with a stable salary, a solo 401k, rental properties, and a decade-plus head start, which is exactly the profile the strategy rewards.

The people it doesn’t help are those looking for a shortcut. There’s no “made $10k this month” moment here, no viral flip. That’s the strategy working as intended, but it means the payoff is invisible for years.

What you’d realistically earn

If you invest steadily in a diversified U.S. equity ETF portfolio, a reasonable long-run planning assumption is the market’s historical ~10% before inflation — call it 6–7% real. Some 15-year windows deliver 16%, as Gouveia’s did. Others deliver 4%. If you’d started in 2000 and held through 2015, you’d have lived through two crashes and a far flatter curve. Planning on 10% and being pleasantly surprised beats planning on 16% and coming up short by half. His result is real; treating it as your forecast is the mistake.

Who this is (and isn’t) for

This suits someone with a steady income, at least a 10-to-15-year horizon, and the temperament to ignore their balance during a 30% drawdown. You need very little time — an hour to set up automatic investing, then mostly nothing. It’s a poor fit if you need income now, can’t leave the money untouched for a decade, or are hoping a portfolio review will reveal a stock that changes your life this year. It won’t.

What to remember

Gouveia is one of the more responsible voices in this corner of YouTube, and the strategy he preaches — cheap, diversified, tax-aware, patient — is the one most professionals would endorse. The single caveat is the number people will remember most: 16% is what the last 15 years paid, not a promise the next 15 will. Plan on 10%, keep buying, and let the math do the boring thing it does best.
