The S&P 500 has surged 30% over the past year, with nearly 20% of that growth driven by a single powerhouse: Nvidia. The semiconductor titan delivered an astonishing 186% return in the last 12 months and now accounts for 7% of the entire S&P 500’s market value, with a staggering $3.6 trillion valuation. But Nvidia isn’t acting alone—it’s part of an elite group known as the "Magnificent Seven", which includes tech giants like Apple, Microsoft, and Amazon. Together, these seven companies have averaged a 56% return over the past year and represent 32.1% of the S&P 500’s total market capitalization.
For investors who’ve missed out on these explosive gains, there’s a simple and effective solution: the Vanguard Mega Cap Growth ETF (MGK). This ETF offers broad exposure to the world’s most dominant AI and technology leaders, with 45.1% of its portfolio concentrated in just four stocks—Nvidia, Apple, Microsoft, and Amazon. It’s a low-cost, high-impact way to align your portfolio with the future of artificial intelligence and digital innovation.
Why the Vanguard Mega Cap Growth ETF Stands Out
The Vanguard Mega Cap Growth ETF holds only 71 stocks, making it highly concentrated in the largest and fastest-growing companies in the U.S. market. Its top holdings are not just household names—they’re foundational players in the AI revolution.
Here’s how the top four positions break down:
- Apple (AAPL) – 13.36%
- Nvidia (NVDA) – 12.52%
- Microsoft (MSFT) – 12.35%
- Amazon (AMZN) – 6.82%
These four alone make up nearly half the fund, giving investors immediate and substantial exposure to companies at the forefront of AI development and deployment.
Apple: Bringing AI to Billions of Devices
Apple recently launched Apple Intelligence, a suite of AI-powered features developed in collaboration with OpenAI. Integrated into the latest iPhones, iPads, and Macs, this software offers advanced writing tools, message summarization, and intelligent photo editing. With over 2.2 billion active devices worldwide, Apple has the potential to become the largest consumer-facing distributor of AI technology.
Its ecosystem lock-in—combined with seamless hardware-software integration—positions Apple uniquely to monetize AI without alienating users concerned about privacy or data usage.
Nvidia: The Engine Behind the AI Boom
Nvidia dominates the market for data center GPUs, which are essential for training large language models and running AI applications. For six consecutive quarters, its data center revenue has grown at triple-digit rates due to overwhelming demand that continues to outpace supply.
Now shipping its next-generation Blackwell architecture, Nvidia’s CEO Jensen Huang has described current demand as “staggering.” As more enterprises adopt AI, Nvidia remains the go-to provider of the computational power that fuels innovation.
Microsoft & Amazon: Cloud Giants Powering Enterprise AI
Both Microsoft and Amazon are not only major investors in AI but also key infrastructure providers. Through Azure and AWS, they purchase vast quantities of Nvidia GPUs and resell cloud-based AI computing power to businesses worldwide.
This model allows smaller firms to leverage cutting-edge AI tools without massive upfront investments. Additionally, both companies have launched their own AI assistants—Copilot and Q, respectively—which could evolve into major revenue streams as enterprise adoption grows.
Beyond AI: A Diversified Portfolio of Market Leaders
While AI stocks dominate headlines—and a significant portion of MGK’s portfolio—the fund isn’t solely reliant on technology. It also includes blue-chip companies across other high-performing sectors:
- Eli Lilly (LLY) – A leader in diabetes and Alzheimer’s treatments
- Visa (V) – Dominant player in global digital payments
- Costco Wholesale (COST) – Retail powerhouse with loyal membership base
- McDonald’s (MCD) – Fast-food giant with strong international growth
This blend of innovation and stability helps balance risk while maintaining strong growth potential.
Low Cost, High Performance: A Winning Combination
One of the most compelling reasons to invest in MGK is its ultra-low expense ratio of just 0.07%. Compare that to the industry average of 0.94%, and it’s clear why cost-conscious investors favor Vanguard funds.
Over time, lower fees translate directly into higher net returns. For example, on a $10,000 investment held for 20 years with an average annual return of 8%, a 0.07% fee would cost you about $144 in annual expenses—versus $940 with a 0.94% fee. That difference can amount to tens of thousands of dollars in savings.
Long-Term Outperformance Against the S&P 500
Since its inception in 2007, the Vanguard Mega Cap Growth ETF has delivered a compound annual return of 13%, outpacing the S&P 500’s average gain of 10.2% over the same period.
Over the past decade, the gap has widened further:
- MGK: 15.9% annualized return
- S&P 500: 13.2% annualized return
This outperformance aligns with the rise of transformative technologies—cloud computing, mobile platforms, enterprise software, and now artificial intelligence.

The Future Is AI—But So Is the Risk
While AI promises enormous economic upside—Goldman Sachs estimates it could add $7 trillion** to global GDP over the next decade, while PwC projects **$15.7 trillion by 2030—it’s not without risk.
If AI adoption slows or fails to deliver expected productivity gains, valuations for many tech stocks could correct sharply. Given MGK’s heavy weighting in Magnificent Seven stocks, investors should view this ETF as a growth accelerator rather than a core-only holding.
It works best within a balanced portfolio—one that includes value stocks, international exposure, bonds, or alternative assets to mitigate concentration risk.
Frequently Asked Questions (FAQ)
Q: What percentage of MGK is invested in technology stocks?
A: As of late 2024, approximately 61.4% of the Vanguard Mega Cap Growth ETF is allocated to the technology sector.
Q: Is MGK a good long-term investment?
A: Historically, yes. With a 13% average annual return since 2007 and exposure to dominant growth companies, MGK has proven its ability to deliver strong long-term performance—especially for investors bullish on tech and AI.
Q: How does MGK differ from VOO (Vanguard S&P 500 ETF)?

Q: Can I lose money investing in MGK?
A: Yes. Like all equity investments, MGK carries market risk. Its concentration in growth and tech stocks makes it more volatile during downturns or tech sell-offs.

A: Yes, though its yield is relatively modest (around 0.6% as of late 2024), reflecting its focus on reinvestment and capital appreciation rather than income.
Q: Should I invest all my money in MGK?
A: No single ETF should dominate a well-diversified portfolio. MGK is best used as a strategic growth component alongside other asset classes.
