Meet the Spectacular Vanguard ETF With 44.6% of Its Portfolio Parked in Nvidia, Alphabet, Apple, and Microsoft

The Vanguard Morningstar Mega Cap Growth ETF (MGK) holds 52 of America's most valuable growth companies, with 44.6% concentrated in Nvidia, Alphabet, Apple, and Microsoft. The ETF has delivered 13.8% compound annual returns since 2007, outperforming the S&P 500's 10.9%, driven largely by AI tailwinds. However, the highly concentrated portfolio and concerns about potential AI data center spending slowdowns present downside risks, making diversification advisable.
