A retirement saver who started ten years ago with nothing fancy, just $100 pulled out of a checking account at the beginning of every month, would have put in $12,000 by this June. One hundred dollars, 120 times, with every dividend reinvested along the way. That framing is useful because it strips away the daydream of "what if I'd dropped $50,000 in" and replaces it with the question most people are actually living: what does the boring monthly habit add up to?
So what did that monthly habit return when invested in three of the most popular ETFs.
What VOO, QQQ and VTI Actually Invest In
When buying an ETF, it is important to look inside it and see what it actually holds, how diversified it is, which industries it exposes you to. More importantly, you look at their historical returns and how they behaved during market downfalls.
Looking at VOO, it holds the S&P 500, the 500 largest U.S. companies as a large-cap blend. It holds 505 stocks, charges 0.03% a year, and has technology sitting at 38.60% of the fund. VTI casts a wider net: it tracks the the CRSP US Total Market Index and allows you to invest in the entire investable U.S. stock market, 3,484 stocks ranging from small to large cap, also at 0.03%. Here's the thing about those two. They overlap so heavily that for most practical purposes they behave like twins, with VTI adding a tail of smaller companies that barely moves the needle.
Invesco’s QQQ is a different animal. It follows the Nasdaq-100, the 100 largest non-financial names on the Nasdaq, and Invesco's own disclosure labels it "non-diversified." Technology runs 66.9% of the portfolio, roughly double the tech weight inside the S&P 500 fund. It holds 102 stocks and charges 0.18%, which is six times VOO's fee, or in plain dollars, $18 versus $3 on every $10,000. There's also a structural quirk worth knowing: the Nasdaq-100 deliberately excludes financial companies, so the banks and insurers you'd get inside a broad-market fund simply aren't there. What's left skews hard toward technology and the consumer-internet names that dominate the Nasdaq listing. That single design choice is one of the reasons why QQQ behaves differently than the other two, especially when you look at how it performed over the past 10 years.
VOO vs VTI: How Similar Are These ETFs?
A quick gut check on how close VOO and VTI really are. VOO's top ten holdings make up 39.23% of the fund; VTI's top ten make up 34.64%. Both top ten lists are identical, same leaders, same order, with VTI's figure a touch lower only because its 3,484-stock tail of mid-caps and small-caps dilutes the concentration slightly. That tail is the entire functional difference between them, and as the dollar results will show, it amounts to very little over a decade.
Investing $100 Monthly: 10-Year Results for VOO, QQQ and VTI
Stoculator’s portfolio backtester was used to calculate how that 10-year investment performed in each of the three ETFs.
QQQ finished with $38,178.62 (as of June 18, 2026). That was $26,178.62 more than the amount contributed, meaning the ending balance was 218.16% greater than total contributions. The portfolio backtester calculated an annualized time-weighted return of 22.07%. That figure measures the performance of the investment while neutralizing the timing and size of the monthly deposits. The backtest also reports $710.60 in dividends, all of which were reinvested at time of distribution and are already included in the ending balance.
VOO finished with $27,826.04 (as of June 18, 2026), $15,826.04 above the $12,000 contributed. Its ending balance was 131.88% greater than the invested amount, and the backtester calculated an annualized time-weighted return of 15.54%. Reinvested dividends totaled $1,409, nearly double QQQ's.
VTI finished with $26,997.07 (as of June 18, 2026). That's 124.98% on the $12,000 invested. Its backtested annualized time-weighted return was 15.05%. Reinvested distributions totaled $1,356.
Why QQQ Outperformed VOO and VTI
So what put a roughly $10,000 gap between QQQ and the Vanguard pair?
Concentration. QQQ holds 66.9% technology against the S&P 500 fund's roughly 38%, and over a decade when the largest tech companies on earth compounded faster than almost anything else, owning a heavier dose of them was the difference. Its top ten holdings alone account for 45.92% of the fund, so when names like NVIDIA and Apple ran, nearly half the portfolio ran with them. VOO and VTI felt that same updraft, just diluted across hundreds or thousands more positions that didn't move as fast.
VOO, QQQ and VTI Holdings: The Same Stocks in Different Weights
Here's the part people miss when they treat QQQ as some exotic bet. It isn't holding secret companies. NVIDIA, Apple, Microsoft, Amazon, Alphabet, Broadcom: the same megacaps you find in all three funds. The difference is dosage.
Take Tesla. It's a shared holding across all three, weighted at 3.17% in QQQ, about 1.9% in VOO, and 1.7% in VTI. The same company, sitting in everyone's portfolio, just in a heavier slice inside the Nasdaq fund. And the history under that holding is messier than a single number suggests. Tesla over the past 10 years lived in the total market fund (VTI) and in the Nasdaq-100 (QQQ) for years, but the S&P 500 only added it effective before the open on December 21, 2020. So VOO did not own Tesla for most of this ten-year window at all. If you're picturing the S&P 500 fund riding Tesla the whole way, it didn't.
This is the quiet argument for diversification rather than a reason to go chase any one of these names. The megacaps are already inside whatever broad fund you hold. The funds differ in how concentrated that exposure is, not in whether you own the giants.
VOO vs QQQ vs VTI: Comparing Risk and Drawdowns
A final number tells you nothing about the road. The road is where most people actually quit.
QQQ's worst stretch wasn't COVID. Its deepest drop was the 2022 rate-hike selloff, a peak-to-trough decline of 33% that began in November 2021, bottomed in October 2022, and didn't fully recover until December 2023. That's a fund cutting nearly a third of its value and then making you wait about two years to get whole. Imagine watching that as someone who is nearing their retirement day.
VOO and VTI had a gentler ride during the same time. VOO fell around 22% and VTI fell around 24%.
Why does this matter if all three recovered and went on to new highs? Because the saver who needed the cash and had to sell QQQ in the depths of 2022 would have locked in that 33% loss and never saw the rebound that produced the $38,178.62.
VOO vs QQQ vs VTI: Do You Have to Choose Just One?
None of this means an investor must choose only one of these funds, nor does it mean the fund that led during the past decade will lead during the next one. VOO or VTI can serve as a broad-market core, while QQQ may be used as a more concentrated growth tilt for investors willing to accept greater volatility. But combining funds is not automatically the same as adding diversification: VOO and VTI overlap heavily, and adding QQQ increases the weight of many megacap stocks already held in both. The more useful question is not which ticker “won,” but what mix of concentration, diversification and risk best fits the investor’s overall portfolio.
