Performance & risk comparison

What's inside

Launched in 1999, QQQ tracks the NASDAQ-100 Index and spans 101 holdings, with a sector mix of 54% technology, 17% communication services, and 13% consumer cyclical. Its largest positions are Nvidia, Microsoft, and Apple, each representing less than 10% of total assets. The fund’s immense scale and long track record make it one of the most traded ETFs in the world.

MGK, by contrast, focuses on the 66 largest U.S. growth stocks. It has similar sector allocations to QQQ, with 57% of the fund devoted to technology, 15% to communication services, and 13% to consumer cyclical. Its top holdings mirror QQQ’s, but with slightly larger allocations to each.

Neither fund includes notable quirks or nonstandard features, and both offer broad exposure to U.S. mega cap growth -- though MGK’s smaller roster may result in more concentrated exposures.

Foolish take

QQQ and MGK both target growth stocks with a specific focus on technology companies. More than half of both ETFs are dedicated to tech stocks, which can lead to above-average returns during tech rallies but also steeper drawdowns amid periods of volatility.

QQQ contains more holdings in total than MGK, which can give it an edge in terms of diversification. Its top three holdings also make up slightly less of the fund's total assets compared to MGK, which also favors diversification.

While QQQ offers a higher dividend yield, its higher expense ratio can erode some of those earnings. Its 0.20% fee is nearly triple MGK's 0.07%, which can be a drawback for investors with large account balances.

In short, QQQ has an edge in terms of its sheer size, diversification, and dividend yield. But MGK shines with its lower fees, and its more targeted focus on mega-cap stocks -- specifically tech stocks -- could potentially lead to higher returns.
