What this means for investors
QQQ and MGK both provide access to growth stocks, but they offer slightly different approaches. While QQQ focuses on large-cap growth stocks, MGK focuses on a smaller basket of mega-cap stocks.
Mega-caps are generally defined as stocks with a market cap of at least $200 billion, which is significantly larger than the $10 billion baseline for large-cap stocks.
MGK is more concentrated than QQQ, which can result in greater risk and reward. While the funds share the same top three holdings, those stocks make up 34.8% of MGK’s portfolio compared to 22.4% for QQQ. This heavier tilt toward tech giants can leader to more volatility for MGK during downturns, but it may also outperform QQQ when those particular companies are thriving.
Fees are also a factor to consider, as QQQ’s expense ratio is more than three times higher than MGK’s. While it may not make a meaningful difference for some investors, those with larger account balances can expect to pay far more per year with QQQ.
