Technology ETFs aim to match their performance to various information technology indexes.

Out of 36 technology ETFs rated by Weiss, just ten made it on the BUY list with an investment rating within the B range. There were no A rated funds in the category.

These ten BUY-rated technology ETFs have above-average 2016 year-to-date performance, nearly all pay a dividend, and all are cheaper than an average industry fund. A portion of their investments are in technology giants like Nvidia, Facebook, Apple, Microsoft, Intel, and others. Keep in mind, these are just a few highly rated stocks among tens, and sometimes hundreds, of an ETF’s holdings. The number of holdings varies from fund to fund, and the overall ETF performance can be impacted by the ups and downs of heavily invested stocks.

In recent days, the expectations of Apple stock going up after the iPhone 7 reveal disappointed many investors. It ended the day of the announcement (September 7, 2016), up only 0.6 percent and dropped 2.6 percent the next day. iShares U.S. Technology ETF reacted in a similar manner--a small gain on the day of the announcement and a drop the next, due to having over 15 percent of its portfolio invested in Apple.

So, when picking an ETF, be sure to review its holdings and see where the fund is putting the majority of your money.

Just one holding can have a significant impact on the overall ETF performance. By knowing where your hard-earned cash might be invested, you can make better and faster decisions as the new market developments unfold.
