SPY vs QQQ: Head-to-Head Comparison

Side-by-Side Comparison

Key Differences Between SPY and QQQ

SPY (SPDR S&P 500 ETF Trust) is a u.s. large-cap blend fund managed by State Street Global Advisors. SPY was the very first ETF listed in the United States and remains the most heavily traded ETF in the world. Like VOO, it tracks the S&P 500 index, but SPY is especially popular among active traders due to its enormous daily trading volume. Beginners should know that SPY and VOO hold the same stocks, but SPY has a slightly higher expense ratio.

QQQ (Invesco QQQ Trust) is a u.s. large-cap growth fund managed by Invesco. QQQ tracks the Nasdaq-100 index, which includes 100 of the largest non-financial companies listed on the Nasdaq stock exchange. It is heavily tilted toward technology and growth stocks, making it a favorite for investors who want concentrated exposure to the tech sector. Beginners should understand that QQQ can deliver higher returns than the S&P 500 in good years but also experiences sharper declines during downturns.

The most notable differences are in fees (9.45% vs 0.20%), number of holdings (503 vs 101), and 5-year returns (15.70% vs 19.50%).
