Designed to provide broad exposure to the Large Cap Growth segment of the US equity market, the Vanguard Morningstar Mega Cap Growth ETF (MGK Quick QuoteMGK - Free Report) is a passively managed exchange traded fund launched on December 17, 2007.

The fund is sponsored by Vanguard. It has amassed assets over $33.45 billion, making it one of the largest ETFs attempting to match the Large Cap Growth segment of the US equity market.

Why Large Cap Growth

Companies that fall in the large cap category tend to have a market capitalization above $10 billion. They tend to be stable companies with predictable cash flows and are usually less volatile than mid and small cap companies.

While growth stocks do boast higher than average sales and earnings growth rates, and they are expected to grow faster than the wider market, investors should note these kinds of stocks have higher valuations. Something to keep in mind is the higher level of volatility that is affiliated with growth stocks. They are likely to outperform value stocks in strong bull markets but over the longer-term, value stocks have delivered better returns than growth stocks in almost all markets.

Costs

Investors should also pay attention to an ETF's expense ratio. Lower cost products will produce better results than those with a higher cost, assuming all other metrics remain the same.

Annual operating expenses for this ETF are 0.05%, making it one of the least expensive products in the space.

It has a 12-month trailing dividend yield of 0.33%.

Sector Exposure and Top Holdings

Even though ETFs offer diversified exposure which minimizes single stock risk, it is still important to look into a fund's holdings before investing. Luckily, most ETFs are very transparent products that disclose their holdings on a daily basis.

This ETF has heaviest allocation to the Information Technology sector -- about 59.6% of the portfolio. Telecom and Consumer Discretionary round out the top three.

Looking at individual holdings, Nvidia Corp (NVDA) accounts for about 13.52% of total assets, followed by Apple Inc (AAPL) and Microsoft Corp (MSFT).

The top 10 holdings account for about 64% of total assets under management.

Performance and Risk

MGK seeks to match the performance of the CRSP U.S. Mega Cap Growth Index before fees and expenses. The CRSP US Mega Cap Growth Index is a float-adjusted, market-capitalization-weighted index designed to measure equity market performance of mega-capitalization growth stocks in the United States.

The ETF return is roughly 8.73% so far this year and it's up approximately 13.89% in the last one year (as of 09/15/2026). In the past 52-week period, it has traded between $70.70 and $92.06.

The ETF has a beta of 1.24 and standard deviation of 19.94% for the trailing three-year period, making it a medium risk choice in the space. With about 59 holdings, it effectively diversifies company-specific risk.
