VGT concentrates on the U.S. information technology sector, delivering a top-tier 38.8% one-year return in this batch. However, its top holdings — Nvidia, Apple, Microsoft — overlap heavily with VOO and VTI, and being sector-concentrated, its max drawdown of -14.1% is substantial.

If you already hold a broad market fund like VOO, adding VGT effectively doubles down on tech exposure. It only makes sense as a modest satellite position for investors with high conviction in tech and tolerance for the added volatility.
