TDTF delivers a specific slice of the intermediate pocket of the US TIPS market. The fund can hold TIPS with maturities ranging from 3 to 20 years, but its primary goal is to maintain targeted duration of roughly five years. TDTF is a take for those looking for predictable duration exposure with inflation protection in the middle of the intermediate TIPS curve. The fund weights constituents using a proprietary methodology to achieve the targeted average modified adjusted duration and its composition is rebalanced monthly.
