The Invesco QQQ Trust: A Millionaire-Maker ETF?

Many of the stocks in the index are the mega-cap tech stocks you might expect to find: Nvidia, Microsoft, Apple, and Amazon.

The Invesco QQQ Trust Series I ETF (NASDAQ:QQQ) tracks the Nasdaq 100 index, which is made up of the 100 largest non-financial stocks that are listed on the Nasdaq stock exchange. The fund offers investors the opportunity to own a broad array of stocks representing many sectors (except for financials).

However, the index is heavily skewed toward the tech industry, with roughly 59% of holdings falling within that sector. Given tech's outperformance over the last few decades, investors should ask themselves: Is it a bad thing to be relatively overweight in the tech sector over the long term? I would suggest -- particularly for younger investors -- that it is not. In fact, staying slightly overweight in the tech sector could prove to be a millionaire-making move. Here's why.

Let's compare the relative performance across four index-linked ETFs: The Invesco QQQ Trust Series I, the SPDR S&P 500 ETF Trust, the SPDR Dow Jones Industrial Average ETF, and the iShares Russell 2000 ETF.

As you can see, over the last five years, the Invesco fund has significantly outperformed the other funds with a compound annual growth rate (CAGR) of 20.5%.

What's more, the difference is even more pronounced if we examine the last 15 years -- starting with the end of the Great Recession bear market, which occurred in March 2009.

Indeed, $50,000 invested in the Invesco fund in March 2009 would have grown to over $1 million today. In comparison, the same amount, invested on the same day, would have grown to only $560,000 in the S&P 500 fund, $454,000 in the Dow fund, and less than $386,000 in the Russell fund.

The lesson? Even with near-perfect timing and very similar index-linked ETF funds, there is an enormous amount of difference in performance among these funds -- and the tech-heavy Invesco fund has proven to be the best.

All that said, there is no guarantee that the Invesco fund will continue its outperformance. After all, there were periods, such as the dot-com bubble of 2001-2003, where tech stocks severely underperformed the broader market. However, even with that turbulent period included, the Invesco fund has ever-so-slightly exceeded the performance of its major index rivals since the start of this century.

No investment is a sure thing, but index-linked ETFs are about as close as you can find. They offer investors a broad range of stocks and have a proven track record of delivering real returns over decades. Moreover, the tech-heavy nature of the Invesco fund offers investors a realistic chance to outperform the market, given the high growth and solid profitability of many of its major components. Investors looking for a smart and simple way to grow their portfolio to over $1 million should consider the Invesco fund.
