SWIB's Board of Trustees set the benchmarks that are used to measure the performance of investment portfolios and the Core and Variable Funds. The benchmarks reflect the objectives of the portfolio and the types of investments that can be made. 

Typically, benchmarks include a widely used market index or a combination of several indexes based on the types of assets. The performance of the benchmark changes based on the performance of the investments held by the index. 

SWIB's benchmarks are listed in the Investment Guidelines. Click here to see the benchmarks for the Core and Variable Funds.
