Vanguard’s S&P 500 ETF (VOO) offers investors exposure to the broader market through a low-cost index strategy, but the fund’s composition includes a heavy weighting toward major technology companies. According to the source text, the fund holds roughly 500 companies and charges an expense ratio of 0.03%.

The ETF’s top holdings are dominated by technology giants. Nvidia Corp (NVDA) accounts for approximately 8.1% of the fund, while Apple Inc (AAPL) holds a 7% position. Microsoft Corp (MSFT) represents 5.7%, Amazon.com Inc (AMZN) is 3.8%, and Alphabet Inc (GOOGL and GOOG) comprises 3% and 2.4%, respectively. Together, these five companies make up roughly 30.4% of the total portfolio. The source notes that a $10,000 investment in VOO would result in about $3,400 being allocated to these five stocks.

Additional exposure to the technology sector is found in other top holdings. Broadcom Inc (AVGO), Meta Platforms Inc (META), Micron Technology Inc (MU), and Tesla Inc (TSLA) add another roughly 7.5% to the fund, bringing the combined exposure of the top nine holdings to nearly 38%.

The article contrasts VOO with the Invesco S&P 500 Equal Weight ETF (RSP), which weights each constituent equally to reduce the influence of mega-cap names like Nvidia, Apple, and Microsoft. The text suggests that while VOO follows the broad-market philosophy often associated with investor Warren Buffett, it also provides significant exposure to the current technology and AI trade.
