What's inside
Vanguard Mega Cap Growth ETF is tightly focused on the largest U.S. growth companies, holding just 69 stocks as of its 18.2-year track record. Its portfolio is dominated by technology (69%) and consumer cyclical (14%) sectors, with top holdings in NVIDIA Corp (NASDAQ:NVDA), Apple Inc (NASDAQ:AAPL), and Microsoft Corp (NASDAQ:MSFT) — together accounting for a substantial portion of assets. This structure offers concentrated exposure to mega cap growth, appealing to investors seeking to track the performance of the market’s biggest names.
Vanguard Growth ETF, by contrast, spreads its holdings across 166 companies, also led by technology (67%) and consumer cyclical (13%) stocks. Its top three holdings mirror those of MGK, but the broader roster means more diversification within the large-cap growth universe. Both funds follow a passive, full-replication approach and share similar sector and company tilts, but VUG’s wider net may appeal to those seeking broader market coverage.

What this means for investors
In recent years, a small group of mega cap growth stocks has driven much of the U.S. market’s returns. This context is important when comparing the Vanguard Growth ETF and the Vanguard Mega Cap Growth ETF.
MGK holds about seventy of the largest U.S. growth companies, making its performance more dependent on a small group of dominant stocks. This approach trades broader participation for greater alignment with mega cap leaders. VUG, on the other hand, includes more than twice as many companies, offering a broader exposure across large-cap growth. While both funds share top holdings and emphasize technology, VUG’s wider roster can capture gains if performance extends beyond the largest firms. The degree of concentration influences how each fund responds to changes in market leadership.
For investors, it’s about finding the right balance. VUG offers you broad exposure to large-cap growth with less focus on just a few stocks. MGK allocates more of your investment to the market’s biggest companies. Your choice will ultimately depend on how much concentration you want in your growth portfolio.
