TDTT approaches the TIPS market with a very specific mandate, holding a combination of TIPS that result in a weighted average portfolio duration of 3 years. To accomplish this, the fund can hold TIPS with maturities ranging from 1 to 10 years. However, in reality, the fund achieves its target duration with precision by typically only holding TIPS with fewer than 5 years remaining in maturities. With shorter maturity and duration than our benchmark, TDTT carries lower nominal yield than our benchmark. The index may use derivatives and is rebalanced on a monthly basis.
