QQQ vs IWM: Head-to-Head Comparison

Side-by-Side Comparison

Key Differences Between QQQ and IWM

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.

IWM (iShares Russell 2000 ETF) is a u.s. small-cap blend fund managed by BlackRock. IWM tracks the Russell 2000 index, which includes 2,000 small-cap U.S. companies. Small-cap stocks are younger, faster-growing companies that have historically delivered higher returns than large-caps over very long time periods, but with significantly more volatility. Beginners should view IWM as a way to add growth potential through smaller companies that could become the large-caps of tomorrow.

The most notable differences are in fees (0.20% vs 0.19%), number of holdings (101 vs 1,955), and 5-year returns (19.50% vs 8.20%).
