This ETF offers broad-based, low cost exposure to U.S. stocks, maintaining more than 1,300 individual holdings across all sectors of the U.S. economy and including companies of all different sizes. As such, IYY may be a useful tools for those building a long-term portfolio and looking to simplify the process; this fund can offer exposure to a core asset class in a single ticker, delivering broad-based U.S. equity exposure to investors. Of course, there are a number of other options available in the All Cap Equities ETFdb Category, and many of these competing funds offer generally similar exposure. This fund maintains fewer holdings than ETFs linked to the Russell 3000 Index, meaning that the exposure offered may be more heavily tilted towards large cap equities. For investors seeking more significant inclusion of small cap and mid cap stocks, it may make sense to use multiple funds to establish U.S. equity exposure, or to achieve complementary exposure through small and mid cap ETFs. IYY is one option for simple, one stop exposure to U.S. equity markets, but investors should note that other products, such as SCHB and FMU, offer similar exposure at a cheaper price. Also, options like VTI or IWV cast a wider net, including significantly more holdings and therefore offering potentially superior balance of exposure.
