This Once-Unstoppable Low-Cost Vanguard ETF Is Underperforming the S&P 500 in 2025. Here's Why It's a Buy Now.

In This Article:

Technology stocks like Nvidia (NASDAQ: NVDA), Apple (NASDAQ: AAPL), and Microsoft (NASDAQ: MSFT) have increased by severalfold over the last decade -- helping drive the S&P 500 (SNPINDEX: ^GSPC) to new heights. But year to date, tech has been one of the worst-performing stock market sectors. A sell-off in the sector can have a major impact on the broader market because tech makes up over 30% of the S&P 500.

It's not just mega-cap tech stocks that are down big year to date. The consumer discretionary sector, led by Amazon (NASDAQ: AMZN) and Tesla (NASDAQ: TSLA), has also sold off. Alphabet (NASDAQ: GOOG) (NASDAQ: GOOGL), which is in the communications sector, is down over 10% year to date at the time of this writing.

Folks looking to scoop up shares in these top companies may want to consider an exchange-traded fund (ETF). The Vanguard Mega Cap Growth ETF (NYSEMKT: MGK) has a mere 0.07% expense ratio, or just $0.70 for every $1,000 invested. As the name implies, the fund is highly concentrated in the largest growth stocks -- making it particularly vulnerable to the current sell-off. However, in the long term, the fund has proven to be a simple yet effective way to compound wealth. Here's why it's a buy now.

Concentration has paid off for the Vanguard Mega Cap Growth ETF

Between the start of 2015 and the end of 2024, the Vanguard Mega Cap Growth ETF increased by a staggering 363% -- significantly beating the S&P 500.

As companies like Nvidia, Apple, and Microsoft have surpassed $3 trillion market caps, they have become a larger share of the S&P 500 -- helping drive strong S&P 500 returns. But the Vanguard Mega Cap Growth ETF is even more concentrated in these top names. In fact, the ETF has a staggering 65.4% invested in its top 10 holdings. As you can see in the table, the fund has a much higher weighting in top growth stocks than the Vanguard S&P 500 ETF (NYSEMKT: VOO), which mirrors the performance of the index.

Concentration can be a double-edged sword. When these stocks are doing well, the ETF has an excellent chance of outperforming the S&P 500. But it's very difficult for the fund to keep pace with the S&P 500 when they are falling.
