VGT vs. QQQ: Which Tech ETF Is the Better Long-Term Buy?

The Invesco QQQ ETF(NASDAQ: QQQ) is one of the most popular ways to invest in technology stocks, but there's a problem with that.

It's not actually a technology ETF.

Missed Nvidia in 2009? This Rare Signal Is Flashing Again. In 2009, a "Double Down" signal flashed for a little-known chipmaker called Nvidia. For the first time in years, that same "Total Conviction" signal is flashing for a company 1/100th the size of Nvidia. Continue »

That's the one thing that matters when comparing it with the Vanguard Information Technology ETF(NYSEMKT: VGT). For investors specifically targeting long-term technology growth, I believe VGT is the better choice.

Why VGT has the advantage

To be clear, the Invesco QQQ ETF is mostly a tech fund. But that's almost by coincidence. Specifically, the fund's objective is to track the Nasdaq-100, which comprises the 100 largest non-financial stocks traded on the Nasdaq. That's it. There's no specific targeting of size, sector, style, or anything else.

It looks like a tech fund because most of the major tech companies have chosen to list their stocks on that exchange. Currently, about 68% of the index is dedicated to tech. The other one-third includes consumer discretionary, telecom, healthcare, industrials, and minor additional allocations elsewhere. It includes Walmart, Costco Wholesale, Amgen, and PepsiCo, some very non-tech holdings.

The Vanguard Information Technology ETF is a pure tech fund. It tracks an index that holds more than 300 positions entirely devoted to tech. Plus, in true Vanguard-ian fashion, its 0.09% expense ratio is one of the lowest in this space and half that of the Invesco QQQ ETF.

If you want tech exposure in your portfolio, choose the tech ETF, not the fund that is mostly a tech ETF.
