SHY is a powerhouse in its segment, stable, liquid vehicle for buy-and-hold investors and short-term traders alike. In addition, SHY is a well managed fund that tracks its index tightly and without significant volatility, like most peer ETFs. The fund delivers excellent coverage of the short-term Treasury space as we see it. SHY and our benchmark share the same index, but the fund's optimization strategyavoiding the index's less liquid components to keep costs downresults in slight performance differences. Still SHY provides excellent exposure to 1-3 year Treasurys. The fund switched its index from the Barclays US Treasury Bond 1-3 Year Term Index to the ICE US Treasury 1-3 Year Bond Index on March 31, 2016. This change effectively maintains the same exposure. Overall SHY is a fine choice for short-dated Treasury exposure.
