Who Really Powered VGT’s Climb This Year?

A handful of winners did the heavy lifting for this tech fund, while some of its biggest names worked against the grain.

One of the smallest holdings in the Vanguard Information Technology ETF (VGT), SanDisk, makes up just 0.7% of the fund. Yet over the past year, it returned +4342%, making it the single biggest contributor to the fund’s overall gain. That one result tells you a lot about the story behind VGT’s headline return of +49.3%.

While you might own the fund for its broad exposure to the tech industry, your return was shaped by a few holdings with very different outcomes.

A Push And A Pull

The fund’s performance wasn’t a simple, uniform rise. It was a tug-of-war. While SanDisk and the next biggest contributor, Micron Technology, added significantly to returns, the fund’s third-largest holding worked in the opposite direction. Microsoft, which makes up 10.0% of the fund, fell 20.1% over the past year, acting as the biggest drag on performance.

This dynamic, where some holdings post large gains while others decline, is normal. The key question for an owner is how widespread the success was. Was the fund’s return a team effort, or the work of a few star players?

How Concentrated Were The Gains?

The answer is that a few names did most of the work. The five biggest contributors produced about 60% of the combined gains from the holdings measured. While more holdings rose than fell, among the 50 largest, 38 rose over the past year and 12 fell, the magnitude of the top performers drove the result. The median holding among that group returned +58.8%, a strong figure that still sits below the returns of the key drivers.

This tells you that the fund’s return was not a broad, even lift across the portfolio. It was concentrated in a handful of holdings that performed exceptionally well.

What This Means for Your Exposure

VGT holds 310 positions, which on the surface suggests deep diversification. But in practice, your investment is more concentrated than that number implies. By weight, the five largest holdings make up 50.6% of the fund. This past year’s performance shows a similar concentration in returns, where a few names delivered an outsized portion of the gains.

Knowing this doesn’t mean the fund is a bad or good investment. It simply clarifies what you own. Your experience is tied heavily to the performance of its largest positions, like Nvidia at 18.6% of the fund, and the chance that a smaller holding delivers a powerful return. Understanding where your real exposure lies is the first step to being a more informed owner.

Which Funds Are Genuinely Diversified?

VGT’s return was the sum of some very different individual results. Two funds with the same label can carry very different concentration, and most buyers never line them up. Our ETF Valuation and Performance Scorecard does exactly that for the full equity universe, sorting by risk-adjusted return and flagging how much of each fund sits in its largest holdings.

If you would rather not weigh it all yourself, the Trefis High Quality (HQ) Portfolio applies the same discipline a level deeper, with 30 individually screened names, rule-based re-balancing, and a record of outpacing a benchmark that combines all major indices – the S&P 500, S&P Mid-cap, and Russell 2000.
