The ETF achieves this by investing in the stocks that make up the index, holding 505 stocks in total. Its top holdings include prominent companies such as NVIDIA Corp (7.31%), Apple Inc (6.63%), and Microsoft Corp (4.96%). Sector allocation is heavily weighted towards Technology (33.1%), followed by Financial Services (12.1%), and Communication Services (10.8%). This ETF is designed for investors seeking long-term capital appreciation through exposure to the overall U.S. stock market. VOO's strategy focuses on mirroring the index, differentiating it from actively managed funds that aim to outperform the index through stock selection. ## Risk Profile VOO, while providing broad market exposure, carries certain risks. A significant portion of the fund is concentrated in the technology sector, with 33.1% allocation, making it vulnerable to downturns in that sector. The top 10 holdings constitute a substantial portion of the fund's assets, introducing concentration risk. With a beta of 1.00, VOO's volatility is expected to be similar to that of the S&P 500. However, the fund's low expense ratio of 0.0300% helps to mitigate the impact of expenses on overall returns. Investors should be aware that past performance does not guarantee future results, and the value of VOO can fluctuate with market conditions. ## Top Holdings - [NVIDIA Corp (NVDA)](https://www.stockexpertai.com/stock/nvda) — **Weight:** 7.31% - [Apple Inc (AAPL)](https://www.stockexpertai.com/stock/aapl) — **Weight:** 6.63% - [Microsoft Corp (MSFT)](https://www.stockexpertai.com/stock/msft) — **Weight:** 4.96% - [Amazon.com Inc (AMZN)](https://www.stockexpertai.com/stock/amzn) — **Weight:** 3.47% - [Alphabet Inc Class A (GOOGL)](https://www.stockexpertai.com/stock/googl) — **Weight:** 3.08% - [Broadcom Inc (AVGO)](https://www.stockexpertai.com/stock/avgo) — **Weight:** 2.56% - [Alphabet Inc Class C (GOOG)](https://www.stockexpertai.com/stock/goog) — **Weight:** 2.46% - [Meta Platforms Inc Class A (META)](https://www.stockexpertai.com/stock/meta) — **Weight:** 2.40% - [Tesla Inc (TSLA)](https://www.stockexpertai.com/stock/tsla) — **Weight:** 1.92% - [Berkshire Hathaway Inc Class B (BRK-B)](https://www.stockexpertai.com/stock/brk-b) — **Weight:** 1.57% ## Sector Allocation - Technology: 33.1% - Financial Services: 12.1% - Communication Services: 10.8% - Consumer Cyclical: 10.1% - Healthcare: 9.9% - Industrials: 8.7% - Consumer Defensive: 5.4% - Energy: 3.5% - Utilities: 2.5% - Real Estate: 2.0% - Basic Materials: 1.9% ## Country Allocation - United States: 97.1% - Ireland: 1.4% - United Kingdom: 0.5% - Other: 0.5% - Switzerland: 0.3% - Netherlands: 0.1% - Bermuda: 0.1% - Canada: 0.0% ## Market Context VOO's performance is closely tied to the overall health and direction of the U.S. economy and stock market.
