IJH is one of the oldest US mid-cap ETFs and, like competitors IVOO and MDY, tracks the S&P MidCap 400 Index. The index, reconstituted annually, is a widely recognized benchmark for capturing the distinct risk and return characteristics for US mid-sized equities. As such, IJH favors smaller firms relative to our large-cap-leaning benchmark. In fact, the fund and our benchmark have a limited number of holdings in common. Still, IJH with its many strengths is a solid choice for midcap exposure.
