VGT vs. XLK: One of These Tech ETFs Has Quietly Beaten the Other for Years

Two funds dominate the conversation whenever investors look for broad, low-cost exposure to U.S. technology: the Vanguard Information Technology ETF (VGT) and the SPDR Technology Select Sector ETF (XLK). Both have delivered strong returns this year, but they take meaningfully different approaches to what counts as "tech" — and that difference shapes how each fund behaves in different market environments.

The scoreboard: 1 year and 5 years

Zoom out past this year's numbers, and XLK has consistently come out slightly ahead over both the trailing one-year and five-year windows — though the two funds have tracked each other closely enough that the gap is more of a steady lean than a runaway blowout.

Core structural differences

While both funds serve as engines for long-term equity growth, their construction differs on several key metrics.

Portfolio construction and concentration

VGT: all-cap exposure. Because VGT tracks an "Investable Market" index, it includes smaller, up-and-coming tech companies alongside the mega-caps. It's still market-cap-weighted, so the largest names still carry outsized influence — Nvidia and Apple together make up roughly a third of the fund — but its 25/50 capping rules keep any single company or group of companies from completely dominating the index.

XLK: a tighter, blue-chip roster. XLK draws only from the technology slice of the S&P 500, which filters out smaller companies entirely and leaves a much more concentrated group of highly capitalized names. Its own concentration limits cap any single holding at roughly 20% of the portfolio at rebalancing.

The GICS classification catch

Investors should also note what isn't in either fund. Under the Global Industry Classification Standard (GICS), Alphabet and Meta are classified as Communication Services, while Amazon falls under Consumer Discretionary. As a result, neither VGT nor XLK holds direct exposure to those three companies, despite their central role in the broader AI and technology story.

So why does XLK keep winning?

The practical difference shows up most in how each fund performs across market cycles. VGT tends to gain an edge when mid- and small-cap tech names rally hard and outperform their mega-cap peers. XLK tends to outperform when the market favors stable, heavily cash-generative mega-caps, or during expansion cycles led by the market's very largest technology companies — a dynamic that has broadly favored XLK across the one-year, five-year, and year-to-date windows in 2026.
