Description

Vanguard S&P 500 ETF (VOO) is a large-cap U.S. equity exchange-traded fund that seeks to track the performance of the S&P 500 Index, a widely used benchmark representing roughly 500 leading U.S. companies and about 80% of the U.S. stock market’s total value. The fund employs a passive, full‑replication strategy, holding essentially all index constituents in their market‑capitalization weights, which supports tight index tracking and broad diversification across sectors such as information technology, financials, health care, consumer, and industrials. With assets under management in the hundreds of billions of dollars and an expense ratio of approximately 0.03%, VOO offers highly liquid, low‑cost exposure to U.S. large‑cap equities, making it a widely used core holding for long‑term investors seeking market‑level returns with transparent structure and efficient implementation.
