State Street?s XLK grants investors the opportunity to gain exposure to numerous powerhouse tech firms all under a single ticker. To be included in this ETF, a company must be one of numerous sectors under the technology umbrella. This includes market segments like IT services, wireless telecommunication services, and semiconductors to name just a few. The fund invests in the who?s-who of the U.S. tech sector, with major holdings in companies like Apple and IBM. The fund splits its assets mainly between the technology and communication services sectors, while allocating mainly to giant and large cap firms. One of the major strengths of this ETF is the fact that it does not single out a particular sector; rather it invests in companies from all across the technology sector. This makes the fund and ideal choice for investors who want tech exposure, but are unsure as to which particular segment of this broad market that they feel will perform the best.
