What The 0.09% Fee Covers
The Vanguard Information Technology Index Fund ETF (VGT) carries a net expense ratio of 0.09%, a rate that places it near the bottom of sector ETF pricing. That figure translates to about $9 per year for every $10,000 invested. Yet the drag from that cost may extend far beyond the sticker price, especially when you run the math on long horizons and compounding returns.
More than a simple fee, the true cost of owning VGT shows up in how your returns are shaped over time. vgt’s 0.09% hides bigger costs that accumulate as the fund compounds, particularly if you already own other U.S. tech exposures. In 2026, market participants have to weigh not just what you pay in fees today, but what you might surrender in future returns due to overlap and concentration.
Hidden Cost: Overlap With Other Tech Bets
VGT is a highly concentrated tech fund. Concentration matters because a handful of names drive most of the performance. For context, Fidelity’s Information Technology ETF (FTEC) shows NVIDIA, Apple, Microsoft, and Broadcom among its top holdings at roughly 18%, 14%, 9.5%, and 5% of net assets, respectively. VGT tracks a similar universe with a comparable concentration pattern. When an investor already holds broad-market exposure—such as an S&P 500 index fund—those same megacaps can appear in multiple places in a portfolio.
The practical consequence is overlap: if you own an S&P 500 fund plus VGT, you’re layering a second bet on top of a stock cluster that already has a big stake in the same four companies. That amplification isn’t obvious from the expense ratio alone, but it can materially affect realized returns over time. Portfolio managers and analysts warn that this hidden drag compounds as the top names remain dominant through market cycles.
- NVIDIA accounts for about 18% of FTEC’s net assets and appears at a similar scale in VGT’s holdings; Apple sits around 14%; Microsoft near 9.5%; Broadcom around 5%.
- Across the four names, the combined weight runs just under 47% of net assets in the comparative ETF data, underscoring how a few stocks can steer a broad sector fund.
- Investors who mix multiple tech bets can unintentionally tilt a portfolio toward a narrow set of megacaps, heightening concentration risk and reducing diversification benefits.
Industry veteran Lisa Carter, ETF strategist at Meridian Capital, says: “The total cost of ownership for tech exposure isn’t just the fee. It’s how overlapping holdings and heavy concentration reshape what you actually own versus what you intended to own.”
Performance Gap Vs. Peers
Even with a low headline expense ratio, VGT’s relative performance has trailed some peers during stretches when the megacaps surge. In the most recent trailing year, VGT delivered about 44.8% in total return, while State Street’s XLK rose roughly 51.25% and Fidelity’s FTEC returned about 45.42% for the same period. Over five years, VGT compounded to about 147.78%, compared with XLK at 167.44% and FTEC at 150.56%.
The difference illustrates a broader point: the cost gap between funds matters, but the return gap—driven by holdings concentration and market dynamics—can be even larger. The small fee advantage can be undone if a fund’s returns lag over multi-year cycles due to its specific stock mix and overlap with other disclosures of tech exposure.
Analysts caution that investors should look at trailing returns, but also at what their portfolios hold in common with other funds. In an environment where megacaps remain central to tech performance, a fund that mirrors those bets may not deliver meaningful diversification on a relative basis.
What Investors Should Do
- Map your total tech exposure across all funds and accounts. Identify where overlap is highest, especially with megacap weights in S&P 500 or other broad tech ETFs.
- Quantify the total cost of ownership, not just the expense ratio. Consider how much of your return drag comes from overlap and concentration, in addition to the stated fee.
- Evaluate alternatives with different concentration profiles. A broader tech index fund or an ETF with a lower overlap profile may offer more efficient diversification.
- Consider an overall portfolio approach that reduces redundant holdings and aligns with risk tolerance and time horizon. Lowering redundancy can help preserve the upside of the top performers while still capturing sector exposure.
“This is not a call to abandon low-cost tech exposure,” says Rafael Diaz, research director at NorthPoint Investments. “It is a reminder to optimize for total cost efficiency and real-world diversification, rather than chasing a single number on a prospectus.”
Bottom Line
vgt’s 0.09% hides bigger costs—an apt description for the quiet, cumulative drag that can accompany overlap and concentration in tech-only funds. As investors field a choppy 2026 equity environment, the lesson is clear: the cheapest fee is not always the best deal if it comes with unintended overlaps that erode long-term returns.
For those building or rebalancing a tech sleeve of their portfolio, the key is to scrutinize not only the stated expense ratio but also how the fund’s holdings interact with your broader stock bets. In a market where a few names drive most gains, careful diversification and awareness of overlap can matter just as much as the charge you see on the statement.
