Most people would like to be a millionaire. But what is the best way to get your hands on a million bucks? In my opinion, the answer is simple: investing. One of the best ways to invest -- and almost certainly the easiest -- is with an exchange-traded fund (ETF). Let's examine one of my favorites, the Vanguard Growth ETF (VUG 0.74%).

What is the Vanguard Growth ETF?

The Vanguard Growth ETF tracks an index of large-cap, growth-oriented stocks, roughly 400 in total, spanning several sectors.

Technology (35%), electronics (27%), and retail (10%) make up the bulk of the fund's holdings. Meanwhile, financials, industrials, and energy stocks comprise less than 5%. From a geographic standpoint, most of the Vanguard fund's holdings are American-based (98%), with a small fraction from Ireland and the U.K.

The fund's top holdings are dominated by the "Magnificent Seven" megacaps, a term used to describe the largest and most influential companies in the market. These companies, including Nvidia, Microsoft, Apple, and Amazon, have consistently shown strong growth and profitability, making them key contributors to the Vanguard Growth ETF's performance.

Company Name Symbol Percentage of Assets
Microsoft MSFT 12.6%
Apple AAPL 11.5%
Nvidia NVDA 10.6%
Alphabet GOOG, GOOGL 7.5%
Amazon AMZN 6.7%

How has the Vanguard Growth ETF performed?

Simply put, the Vanguard Growth ETF has been one of the best broad-based ETFs to own over the last decade. A $10,000 investment in the fund made in 2014 would now be worth $42,000, representing a compound annual growth rate (CAGR) of 15.4%. This means that, on average, the fund's value has grown by 15.4% each year over this 10-year period.

That easily outpaces the performance of the SPDR S&P 500 ETF Trust, an ETF that tracks the performance of the S&P 500 index. In fact, the Vanguard Growth ETF has consistently outperformed many other broad-based ETFs in its category over the past decade, such as the Vanguard Value ETF, a fund that tracks an index of value stocks.

What's more, investors in the Vanguard ETF pay a minuscule expense ratio of 0.04%. This means that for every $10,000 invested in the fund, only $4 per year is charged in fees. That's one of the lowest fee structures available for an ETF and is great news for investors. Large fees can stunt investment growth by siphoning off money and slowing the accruing gains of compounding.

Is the Vanguard Growth ETF a buy now?

So, the question remains: Is now the right time to invest in the Vanguard Growth ETF?  In short, consistent investments in broad-based index funds are one of the best ways to accumulate wealth. What's more, by avoiding the pitfall of trying to time the market, long-term buy-and-hold investors improve their investments' rate of return.

Finally, with its low-fee structure, the Vanguard fund ensures that investors -- rather than the fund's administrators -- reap the most benefit from the investment returns.
