This ETF is one of several options offering exposure to the U.S. industrials sector, offering a way to access a corner of the U.S. economy that includes transportation firms, providers of commercial and professional services, and manufacturers of capital goods. Given the sector-specific focus, VIS likely doesn't deserve a core allocation, but may be useful as a means of implementing a tactical tilt towards the industrials sector or as part of a sector rotation strategy. Like many Vanguard ETFs, VIS is attractive in the expense department; in addition to one of the lowest expense ratios in the category, this ETF may be available for commission-free trading in Vanguard accounts. The depth of VIS portfolio is also attractive, though this fund, like many other industrials ETFs, has a big concentration in GE stock. Those seeking to avoid this concentration may want to consider the equal-weighted RGI; those seeking exposure to ex-U.S. industrials may find IPN to be a useful tool.
