S Fund

Small cap stock Index investment fund

First, let's answer a few questions.

  • While investment in the S Fund carries risk, it also offers the opportunity to experience gains from equity ownership of small-to-mid-sized U.S. companies. It provides an excellent means of further diversifying your domestic equity holdings.

  • There is a risk of loss if the Dow Jones U.S. Completion TSM Index declines in response to changes in overall economic conditions (market risk) or if S Fund investments do not outpace or grow enough to offset the reduction in purchasing power (inflation risk).

  • The S Fund can be useful in a portfolio that also contains stock funds that track other indexes. The C, S, and I Funds, for example, track different segments of the overall stock market without overlapping. By investing in all segments of the stock market (as opposed to just one), you reduce your exposure to market risk.

The S Fund's investment objective is to match the performance of the Dow Jones U.S. Completion Total Stock Market Index, a broad market index made up of stocks of small-to-medium U.S. companies not included in the S&P 500 Index.

    Additional information

    The FRTIB’s Executive Director currently allocates the selection, purchase, investment, and management of assets contained in the S Fund to BlackRock Institutional Trust Company, N.A., and State Street Global Advisors Trust Company. The Fund is invested in the Dow Jones U.S. Completion TSM Index, which contains a large number of stocks, including illiquid stocks with low trading volume and stocks with prices lower than $1.00 per share.

    Therefore, it is not efficient for the Fund to invest in every stock in the index. The S Fund holds the stocks of most of the companies in the index with market values greater than $1 billion. However, a mathematical sampling technique is used to select among the smaller stocks.

    The performance of the S Fund is evaluated on the basis of how closely its returns match those of the Dow Jones U.S. Completion TSM Index. A portion of S Fund assets is reserved to meet the needs of daily client activity. This liquidity reserve is invested in futures contracts of the S&P 400 and Russell 2000 (other broad equity indexes).
