VGT Looks Like a Diversified Tech Bet Until You Realize Three Stocks Are 43 Percent of It

VGT is a sector-focused ETF that charges nine basis points to provide exposure to the U.S. information technology segment. As of March 31, 2026, NVIDIA, Apple, and Microsoft account for about 43% of assets, with the top ten holdings around 60% and the remaining holdings making up roughly 40%. The fund tracks a cap-weighted index with regulatory diversification caps that allow a top-heavy structure. Fund performance is closely tied to major earnings and guidance from these three companies, with large portions of daily moves linked to their results. Recent quarterly revenue growth across the three holdings is substantial, but diversification is tested by the 2022 mega-cap downturn, when VGT fell about 30% and XLK fell nearly 31% peak to trough.

"As of March 31, 2026, three names carried the fund. NVIDIA ( NASDAQ:NVDA) at 18.6%, Apple ( NASDAQ:AAPL) at 14.8%, Microsoft ( NASDAQ:MSFT) at 10.02%. That is ~43% of VGT in three companies, with the next seven holdings adding roughly 15%, which means the top ten run about 60% of the fund. The remaining ~318 holdings split the other 40%."

"VGT tracks the MSCI US Investable Market Index/Information Technology 25/50, a cap-weighted index with regulatory diversification caps that are loose enough to permit exactly this kind of top-heavy structure. When NVIDIA reports earnings, roughly 18 cents of every dollar in VGT moves with the print. When Apple guides iPhone, another 16 cents respond. Microsoft does the same with Azure growth, which is currently running at +40% year over year."

"Moreover, NVIDIA posted Q1 revenue up 85% year over year to $81.62 billion. Apple delivered Q2 FY26 revenue of $111.18 billion. Microsoft's Q3 FY26 came in at $82.89 billion, with Azure growing 40% and an AI business now at a $37 billion annual run rate, up 123% year over year. Three companies, roughly $260 billion of quarterly revenue, and they sit inside a single ETF ticker."

"Test it against 2022, the canonical mega-cap stumble. VGT finished that year down 30%. The Technology Select Sector SPDR ( NYSEARCA:XLK), often pitched as the alternative and currently holding 39% in the same three names, fell nearly 31% peak to trough. Two products marketed as diversified tech exposure lande"
