The Vanguard S&P 500 ETF (VOO) has reached $1 trillion in assets, but what’s inside the wrapper is not as diverse as it seems. At its core, VOO tracks the S&P 500, which means investors are buying into a concentrated bet on just a few mega-cap technology businesses.
In reality, VOO holds only nine individual stocks, with eight of them being software or semiconductor companies. NVIDIA, Apple, and Microsoft dominate the fund, with their combined market value accounting for over a third of the assets. This concentration of risk means that if two or three of these top holdings decline, the entire index can suffer.
The fund’s structure also leads to factor exposure, as it weights its investments towards the winning theme in the market at any given time. This can result in investors being exposed to growth strategies that are not aligned with their overall investment goals.
For long-term investors, VOO can be a useful core US equity component, but it’s essential to view it as a concentrated large-cap growth fund rather than an index fund that represents the entire market. To achieve genuine breadth, investors should consider adding other pieces to the portfolio.
VOO’s low fee of 0.03% has worked for its investors so far, with returns of around 22% over the past year and 84% over five years. However, it’s crucial to understand the underlying composition of the fund and how it aligns with one’s investment objectives.
