TIP, launched in late 2003, had a three-and-a-half-year head start to accumulate assets before its first ETF competitor stepped onto the TIPS scene. It seeks to track an index that holds a broad and diversified portfolio of TIPS with at least one year remaining in maturity. Securities included in the fund must be USD-denominated. These securities must also be issued by and backed by the full faith and credit of the US government. The underlying index uses market capitalization as its selection and weighting criteria. Prior to January 31, 2023, this fund tracked the Bloomberg U.S. Treasury Inflation Protected Securities (TIPS) Index.
