TSP Funds: Descriptions and Intraday Quotes

TSPkey.com's allocations use one or more of the five primary Thrift Savings Plan funds: the G, F, C, S and I Funds. We don't use the Lifecycle funds, as they're simply diversified versions of the primary funds. If you're new to the TSP, or would like a brief refresher on the funds, please see these official descriptions from the TSP.gov website:

G Fund

F Fund

C Fund

S Fund

I Fund


The C, S and I Funds are based on different stock indices. The C Fund tracks the S&P 500, the S Fund tracks the Wilshire 4500 small/midcap index and the I Fund follows the EAFE (Europe, Australasia, Far East) index.

The F Fund is based on the Lehman Brothers U.S. Aggregate (LBA) bond index. The G Fund invests solely in short-term U.S. Treasury bonds. Like a money market account, the G Fund is considered a "risk-free" investment because it never has a negative return. This security comes with a price, however. Historically, the G Fund has the lowest return of the five TSP funds.

The TSP fund prices aren't updated until after the market's close each day. However, you can track indices and exchange-traded funds (ETFs) that mirror the TSP Funds on an intraday basis.

We've listed quotes for these "proxy" funds below. To see how the funds doing during the day, you may want to bookmark this page for easy reference.
