I Opened a Stock Account for My 7-Year-Old. Here’s Exactly What I Bought.

It Started With a Simple Question

My 7-year-old asked me what I was doing on my phone.

I told him I was checking his investment account.

He looked at me like I’d said something in a foreign language. “What’s an investment account?” he asked.

And honestly? That question was exactly why I opened it.

I don’t want my kids to be adults who feel lost when someone mentions stocks, ETFs, or compound interest. I was that adult. I didn’t start investing until way later than I should have — and I don’t want that for them.

So I decided to start early. Really early.

Why I Started at Age 7 (and 3)

My oldest is 7. My youngest just turned 3.

Both of them now have investment accounts. Both of them have money in the stock market right now, growing quietly in the background while they play with LEGO and watch cartoons.

The reason I started so young isn’t because I think a 7-year-old needs to understand portfolio theory. It’s because of one word: time.

The single most powerful force in investing is compound interest — and compound interest needs time to work. A dollar invested today at age 7 has over 60 years to grow before my son retires. That’s 60 years of compounding. Starting at 30 instead of 7 cuts that in half.

I wrote about compound interest in detail here: What Is Compound Interest?

The best time to start was yesterday. The second best time is today.

What I Actually Bought — My 7-Year-Old’s Portfolio

I kept it simple. No individual stocks. No trying to pick winners. Just two ETFs that cover the whole market.

Here’s his exact portfolio right now:

QQQM — 40%
This tracks the Nasdaq-100 — the 100 largest non-financial companies on the Nasdaq, heavily weighted toward tech. Apple, Microsoft, NVIDIA, Amazon, Meta. The companies defining the next 20 years.

VOO — 60%
This tracks the S&P 500 — the 500 largest companies in the US. Broader than QQQM, more stable, less volatile. Warren Buffett’s recommended index fund for most investors.

Total invested: ~$5,500.
Current value: ~$6,000 — up about 9% in roughly 2–3 months.

Nothing dramatic. No overnight gains. Just steady, quiet growth — exactly the way long-term investing is supposed to work.

Why This Specific Combination?

I chose 60% VOO for stability and 40% QQQM for growth.

VOO gives him the broad market — reliable, diversified, time-tested. QQQM adds a tilt toward tech and innovation, which I believe will outperform over the next few decades.

Together, they cover both bases: the safety of the entire US market, with a lean toward the sector most likely to drive growth during his investing lifetime.

Is this the “perfect” portfolio for a 7-year-old? Probably not — there’s no such thing. But it’s simple, low-cost, and built for the long term. That’s what matters most when you have 60+ years of runway.

My 3-Year-Old’s Portfolio — 100% QQQM

For my youngest, I went 100% QQQM.

Why more aggressive for the younger one? Because he has even more time. A 3-year-old investing today has potentially 65+ years before retirement. With that kind of runway, short-term volatility doesn’t matter at all — what matters is maximizing long-term growth.

QQQM has historically outperformed VOO over long periods, but with more volatility. For a 3-year-old who won’t touch this money for decades, that volatility is irrelevant. The growth potential is what counts.

Current balance: $750. Started with $740 about a month ago — already up slightly.

And every month, I add ~$75 to each account. Allowances and birthday money go in too.

The Monthly Investing Plan

Lump sums are great, but the real power comes from consistency.

Every month, ~$75 goes into each account — automatically, without thinking about it. When markets are up, we buy. When markets are down, we buy more shares for the same price. This is called dollar-cost averaging, and it’s the most beginner-friendly investing strategy that exists.

I also plan to add any allowance money they receive. Birthday gifts from grandparents. Pocket money they don’t spend. Instead of disappearing into toys they forget about in two weeks, that money goes into their accounts — where it has decades to grow.

They’re too young to fully understand this now. But one day they will.

What I Tell My 7-Year-Old About His Account

He can’t quite grasp “you own tiny pieces of Apple and Microsoft” yet.

So I explain it differently.

I tell him: “You have a piggy bank that gets smarter every year. The longer you leave it alone, the bigger it grows. One day, when you’re grown up, it might help you buy a house, start a business, or just give you choices that other people don’t have.”

He nodded and went back to his LEGO.

That’s fine. The seed is planted. And the account is growing whether he thinks about it or not.

Why I’m Sharing This

I’m not a financial advisor. I’m just a regular dad who started investing later than he should have and doesn’t want his kids to make the same mistake.

Everything I’ve learned about ETFs, index funds, and long-term investing is documented on this blog — in plain English, for people like me who figured this out later in life.

If this post made you think about opening an account for your own kids, that’s the point. You don’t need a lot of money. You don’t need to be an expert. You just need to start — and start early.

Time is the one advantage your kids have that no amount of money can buy back later.
