TLT

While taking a different approach from our benchmark, TLT effectively captures the far end of the Treasury curve in a liquid package. Exclusively holding bonds with 20+ years to maturity, TLT is—by design—very sensitive to long-term interest-rate movements. The fund has higher duration than our benchmark, which holds bonds in the 10- to 30-year range. The fund changed its underlying index from the Barclays US 20+ Year Treasury Bond Index to the ICE US Treasury 20+ Year Index on March 31, 2016. This change did not alter the fund's exposure in a meaningful way. TLT is a great choice for investors who want long-term Treasury exposure.
