This ETF is one of several ETFs available that offers exposure to mid cap U.S. stocks, an asset class that can make up a significant portion of long-term, buy-and-hold portfolios. As such, this ETF may be more appealing to those in the portfolio construction process as opposed to short term traders. While most funds in this Category focus exclusively on mid caps, this fund also includes small caps as well making it an interesting choice for investors seeking exposure to both market cap levels in a single ticker. VXF offers exposure to a balanced portfolio of stocks, including close to 3,000 individual names and spreading exposure relatively evenly suggesting that fund is extremely diversified. The expense ratio is among the cheapest in the category making it an excellent choice for those looking to keep costs to an absolute minimum. For those seeking other options in the space that provide exposure only to mid caps, MDY and IJH could make for good choices as well as the ultra-cheap FMM, and equal-weighted EWRM. However, for those seeking both mid and small caps in a single product, VXF is tough to beat.
