Understanding the Vanguard Mega Cap ETF
The S&P 500 and its closely associated Vanguard S&P 500 ETF have historically been effective for long-term wealth growth. Nowadays, with the rise of low-cost ETFs, investors can explore a range of products that align better with their financial goals, often without hefty fees.
For instance, the Vanguard Mega Cap ETF has an expense ratio of 0.07%. That’s slightly higher than the 0.03% of the Vanguard S&P 500 ETF, which translates to a difference of $4 for every $10,000 invested.
You might wonder why someone would opt for the Vanguard Mega Cap ETF over the Vanguard S&P 500 ETF if they’re focusing on major S&P 500 stocks. Well, this particular ETF centers on MegaCap growth, dividends, and value stocks, whereas other Vanguard options like the Growth ETF filter out value stocks, and the Value ETF excludes growth stocks altogether.
In this way, Mega Cap ETFs tend to emphasize larger companies more effectively than the smaller firms within the S&P 500. The Mega Cap ETF holds just 185 stocks, in contrast to the 504 held by the Vanguard S&P 500 ETF. This narrower focus can be seen in their top 20 holdings.
| Company | Weighting of Vanguard Mega Cap ETF | Vanguard S&P 500 ETF Weighting |
|---|---|---|
| Nvidia | 9.2% | 8.1% |
| Microsoft | 8.8% | 7.4% |
| Apple | 6.9% | 5.8% |
| Amazon | 5% | 4.1% |
| Alphabet (Google) | 4.5% | 3.8% |
| Meta Platforms | 3.7% | 3.1% |
| Broadcom | 3.1% | 2.6% |
| Tesla | 1.9% | 1.6% |
| JPMorgan Chase | 1.8% | 1.5% |
| Berkshire Hathaway Class B | 1.8% | 1.6% |
| Eli Lilly | 1.4% | 1.1% |
| Visa | 1.3% | 1.1% |
| Netflix | 1.1% | 0.9% |
| ExxonMobil | 1.1% | 0.9% |
| Mastercard | 1% | 0.9% |
| Walmart | 1% | 0.8% |
| Oracle | 1% | 0.8% |
| Costco Wholesale | 0.9% | 0.8% |
| Johnson & Johnson | 0.9% | 0.7% |
| Home Depot | 0.8% | 0.7% |
| Total | 57.2% | 48.3% |
As noted, the top 20 holdings in the Mega Cap ETF account for over half of its total value, while for the S&P 500, that number is less than half. This reallocation reflects a more concentrated approach that has emerged recently. Large-cap growth stocks significantly influence the index, contributing around 38% to the S&P 500.
Essentially, Mega Cap ETFs lean towards growth by prioritizing a smaller group of major stocks. For example, top firms like Nvidia, Microsoft, Apple, Broadcom, and Oracle together represent an astounding portion of the overall ETFs. This focus affects how much these stocks sway their respective sectors.
Interestingly, this emphasis has resulted in Mega Cap ETFs boasting a gross return rate of 308.1% over the past decade, compared to 284.2% for the S&P 500 ETF. The Mega Cap ETF features a price-to-earnings (P/E) ratio of 28 and a dividend yield of 1%, whereas the S&P 500 ETF has a slightly lower P/E ratio of 27 and a yield of 1.2%. It seems to cater more to growth-focused investors.
For those seeking an affordable, diversified way to access the largest US companies, the Vanguard Mega Cap ETF can be quite appealing. A common strategy involves combining this ETF with individual stocks that might not have large market shares but offer good potential.
Considering the S&P 500 comprises nearly $53.6 trillion in market capitalization, you need a company with roughly $536 billion in market value to represent 1% of the index. Pairing the Mega Cap ETF with smaller companies fosters a more diverse investment while still engaging with leading firms driving market growth.
In summary, the Vanguard Mega Cap ETF emerges as a potentially smarter choice for some investors looking to access top S&P 500 stocks more effectively than through the traditional Vanguard S&P 500 ETF.
