Vanguard Tech Fund Nears 800% Decade Return
The Vanguard Information Technology Index Fund has delivered a 799% ten-year return, but its heavy concentration in a handful of AI giants exposes investors to severe single-stock risk.
The Vanguard Information Technology Index Fund ETF has swelled to $146.5 billion in assets after posting a 799% total return over the past decade. The fund has gained 23.4% year-to-date and 36% over the past twelve months, driven almost entirely by capital appreciation in the largest American technology platforms.
This performance reflects the sheer scale of capital flowing into AI infrastructure. AI chip stocks collectively added $2 trillion in market value in July 2026. Concurrently, the Philadelphia Semiconductor Index has surged more than 47% this year. For a flat fee of 0.09%, VGT offers unmanaged, liquid exposure to this specific hardware build-out.
The fund tracks the MSCI US Investable Market Information Technology 25/50 Index. While it holds over 315 individual stocks, the return engine relies on a tight cluster of dominant operating system, cloud, and AI silicon companies. When these platform giants grow their earnings, the fund rises. When they stumble, there is no hedge or overlay to absorb the shock.
That structural simplicity creates acute vulnerability. The top three holdings control roughly 40% of the fund's total weight. Nvidia, which holds an estimated 70% to 80% share of the AI GPU market, demonstrated this risk in June 2026. When the chipmaker lost $588 billion in market capitalization that month, VGT suffered a disproportionate hit.
Over the last decade, VGT’s 24% annualized return has beaten broader market peers specifically because it excludes the retail, media, and consumer names that dilute standard technology benchmarks. It provides arguably the purest liquid exposure to the US tech sector available at this cost.
Despite the impressive arithmetic, the extreme concentration makes a full portfolio allocation dangerous. Market professionals note that sizing VGT between 10% and 20% alongside a broad-market core allows investors to harvest AI-driven compounding. This approach captures the sector's upside without tying a portfolio entirely to a single, highly volatile semiconductor cycle.
