Wilshire Bond Index

The Wilshire Bond IndexSM measures the performance of the U.S. taxable fixed income market based on actual holdings of U.S. institutional investors. The Wilshire Trust Universe Comparison Service® (Wilshire TUCS® ) database representing over $3.7 trillion in institutional assets is used to dynamically define the institutional U.S. bond market. Fixed income holdings from approximately 2,000 leading edge U.S. institutions are aggregated to update the index membership quarterly. Introduced in 2016, with a time series of data beginning on June 30, 2004, the Wilshire Bond Index delivers a performance and risk profile consistent with the taxable fixed income opportunity set as chosen by institutional investors, making it a measure that more accurately reflects the true U.S. fixed income opportunity set and risks.
