Both the Vanguard Mega Cap Growth ETF (NYSEMKT:MGK) and the Invesco QQQ Trust, Series 1 (NASDAQ:QQQ) target the giants of the U.S. market, focusing on high-growth companies that dominate their respective industries.
While QQQ tracks the 100 largest non-financial firms on the Nasdaq, MGK follows a mega-cap growth index, resulting in two portfolios with significant overlap but distinct risk-reward profiles for growth-oriented investors.

Beta measures price volatility relative to the S&P 500; beta is calculated from five-year monthly returns. The 1-yr return represents total return over the trailing 12 months.
MGK is the more affordable option, as its expense ratio is less than a third of that of QQQ. While both funds provide low-cost access to growth, the difference in fees can impact long-term accumulation for high-balance accounts.

What this means for investors
QQQ and MGK both target large growth companies, but MGK is the narrower of the two. QQQ focuses on both large- and mega-cap stocks, while MGK specifically targets mega-caps.
Tech stocks make up just over half of each fund’s portfolio, but MGK is more concentrated in its top three holdings. Nvidia, Apple, and Microsoft account for 35.31% of MGK’s portfolio, compared to 20.87% for QQQ. This could potentially lead to a difference in total returns — for better or worse — depending on how those particular stocks perform.
Risk profiles are similar, with the two funds showing comparable betas and max drawdowns. However, QQQ has slightly outperformed MGK in both one- and five-year total returns.
Fees could also be a selling point for some investors. MGK charges a lower expense ratio of 0.05%, compared to QQQ’s 0.18%. This means you’ll pay $5 per year in fees for every $10,000 invested in MGK, or $18 per year for every $10,000 invested in QQQ. Over time, this could add up to thousands of dollars in fees.
