This ETF seeks to replicate a benchmark that is comprised of various software companies. IGV, an iShares product, invests in only U.S. companies, so this may not be the right fund for those who wish to gain exposure on a global scale. At first glance, investors may assume that the ETF would invest in mega cap software firms, when in actuality, the fund invests primarily in medium cap companies, giving investors access to a fair amount of lesser-known, potentially high growth firms. With that being said, a number of large well-known firms dominate the top of this index as high weightings are given to Oracle, Microsoft, and Adobe. As a result, investors should take a closer look at their overall portfolio to make sure that they aren't doubling down on this sector by investing in this fund as many of the top holdings will already be in large cap equity products as well. Many investors may be better off by looking at a more diversified tech ETF that offers exposure to multiple sectors instead of the software industry which is facing headwinds thanks to cloud computing and rampant piracy.
