ETF Comparison: Invesco QQQ ETF (QQQ) Versus Vanguard Information Technology ETF (VGT)

QQQ vs. VGT: Total Cost of Ownership

On expense ratio alone, VGT wins easily at 0.09%, after Vanguard trimmed it down from 0.10% earlier this year. QQQ, by comparison, charges 0.20%—not egregious on its own, but relatively expensive in 2025’s ultra-competitive ETF landscape.

When it comes to implicit costs, QQQ is one of the most liquid ETFs on the market, with a 390-day median bid/ask spread of just 0.004%. That means it costs virtually nothing to trade. VGT is still highly liquid, but its spread is higher at 0.042%, which could matter more for frequent traders.

Verdict: When combining expense ratio and trading costs, VGT is still clearly cheaper to own over the long term. Don’t expect Invesco to cut QQQ’s fees anytime soon—at nearly $300 billion in assets, it remains one of the firm’s most lucrative products.

QQQ vs. VGT: Methodology and Exposure

Both ETFs provide clear and concentrated exposure to the tech sector—but they get there in very different ways.

QQQ tracks the Nasdaq-100 Index, a relatively simple benchmark built on three main rules: exclude financials, take the 100 largest non-financial stocks listed on the Nasdaq, and weight them by market cap. That’s about it.

Historically, because the Nasdaq exchange attracted many tech-heavy growth companies, the index evolved into a quasi-tech benchmark—even though it was never designed specifically for that purpose.

VGT, on the other hand, is far more intentional. It tracks the MSCI US Investable Market Information Technology 25/50 Index, which includes over 300 large-, mid-, and small-cap U.S. companies classified under the GICS (Global Industry Classification Standard) tech sector.

That includes traditional segments like semiconductors, software, tech hardware, cloud computing, and data centers. But there’s a catch.

Because GICS classifications don’t always line up with public perception, VGT excludes companies like Amazon and Tesla (classified as consumer discretionary) and Meta and Alphabet (grouped under communication services). So, while VGT is tech in the purest GICS sense, it can feel narrower than expected.

Despite holding more stocks, VGT is more concentrated in tech than QQQ. QQQ includes a broader mix of sectors—mostly tech, but also big names in consumer discretionary, communication services, and even consumer staples like Costco and Pepsi, which just happen to list on the Nasdaq. VGT is also more top-heavy, with a larger share of assets tied up in its top few names.

Verdict: While I’m not a fan of how QQQ selects stocks based on which exchange they’re listed on, it does offer slightly more diversification and arguably better reflects the real-world footprint of modern tech, even if that’s by accident. VGT, though more narrowly defined, sticks strictly to GICS sector lines.

QQQ vs. VGT: Risk and Return

Unsurprisingly, both ETFs have been strong performers over the short term, with impressive three-year annualized returns—though both have taken a hit year to date amid the broader market pullback. Still, investor appetite remains robust, especially for QQQ, which has seen $5.2 billion in net inflows so far in 2025 despite the downturn.

On the risk side, VGT has historically been more volatile, with a higher standard deviation and deeper max drawdowns. That’s largely due to its pure-play tech exposure. While QQQ is heavily tilted toward technology, it still includes companies from other sectors, which can help soften the blow during sharp sell-offs.

Looking at long-term performance from January 30, 2004, through March 31, 2025, QQQ edges out VGT with a 13.61% compound annual growth rate (CAGR) versus 13.01% for VGT. QQQ also delivered a higher Sharpe ratio of 0.63 vs. 0.59, indicating better risk-adjusted returns over that period.

Verdict: This one’s clear—VGT is too concentrated in a single GICS sector to serve as anything more than a tactical overweight. And while QQQ’s exchange-based index methodology has its flaws, its long-term results speak for themselves.
