Introduction to SPY ETF
The SPY ETF, formally known as the SPDR S&P 500 ETF Trust, is one of the most recognized financial instruments in the world. Launched on January 22, 1993, SPY was the first-ever exchange-traded fund (ETF) listed in the United States.
Its primary purpose is simple: to track the performance of the S&P 500 Index, which represents the 500 largest publicly traded companies in the U.S. By owning SPY, investors gain exposure to the entire U.S. stock market’s most influential companies with a single investment.
As of 2025, SPY has grown into the largest ETF globally, with over $600 billion in assets and an average daily trading volume exceeding $20 billion—making it one of the most liquid investment vehicles available.
How the SPY ETF Works
SPY is designed to mirror the S&P 500 Index. Since the index is market-cap weighted, larger companies like Apple, Microsoft, and NVIDIA make up a bigger share of the portfolio.
Structure
- Fund Type: Unit Investment Trust (UIT)
- Trading Venue: NYSE Arca
- Trustee: State Street Bank & Trust
- Distributor: ALPS Distributors
Unlike actively managed funds, SPY is passively managed. This means its portfolio automatically adjusts when the S&P 500 index changes, keeping tracking errors minimal (about 0.02%).

Costs and Fees
SPY has an expense ratio of 0.0945%, meaning an investor pays $9.45 annually for every $10,000 invested.
