MGK is built for investors seeking focused exposure to U.S. mega-cap growth stocks, tracking the largest companies with a portfolio of just 60 stocks.
Technology dominates, making up 55% of the fund, followed by communication services and consumer cyclical. Its top holdings — Nvidia, Apple, and Microsoft — collectively make up more than 35% of the fund.
By contrast, VOOG spreads its bets across 140 growth-oriented stocks, with technology making up 49% of total assets. Its secondary sectors include communication services and consumer cyclical.
Its top three positions match MGK’s but are somewhat less concentrated, making up around 32% of the portfolio. This broader sector and stock exposure may appeal to those seeking slightly more diversification within the U.S. growth universe.

VOOG and MGK both focus on growth stocks, but they offer differ approaches to this segment of the market.
VOOG only includes stocks from companies included in the S&P 500. That can add an element of stability to this investment, as this index is made up of the largest and strongest U.S. companies. With more than double the number of holdings of MGK, it also boasts greater diversification.
