Do TSP funds have ticker symbols?
No. TSP funds have no ticker symbols, because they aren't traded on an exchange. They're open only to people with a TSP account, and each fund gets one share price per business day, set after the markets close. What each fund does have is a stated objective: the C, S, I and F Funds are each built to match a named index. The latest closing price for every fund is on our TSP share prices page.
The index behind each TSP fund
| TSP fund | What it's built to match (tsp.gov) | Public funds that use the same index |
|---|---|---|
| C Fund | S&P 500 Index | iShares Core S&P 500 ETF (IVV), Vanguard S&P 500 ETF (VOO) |
| S Fund | Dow Jones U.S. Completion Total Stock Market Index | None listed here |
| I Fund | MSCI ACWI IMI ex USA ex China ex Hong Kong Index | No exact match listed here (see below) |
| F Fund | Bloomberg U.S. Aggregate Bond Index | iShares Core U.S. Aggregate Bond ETF (AGG) |
| G Fund | No index: U.S. Treasury securities issued specially to the TSP | None |
The examples show which public funds share an index, for comparing daily direction. They aren't TSP funds and they aren't suggestions. Fees, cash flows and pricing differ, so their returns won't line up exactly.
Why the I Fund has no exact twin
The I Fund's index leaves out China and Hong Kong. The iShares Core MSCI Total International Stock ETF (IXUS), for example, uses the MSCI ACWI ex USA IMI Index, which doesn't carry those exclusions. That makes it a close relative, not a copy. The I Fund index guide covers the 2024 change. The I Fund can also differ from its index on a given day, which our share price guide explains.
What about the L Funds?
L Funds have no ticker symbols either. Each one is a mix of the G, F, C, S and I Funds, and that mix changes over time, so no single index matches it. The L Funds guide shows the current target mixes.
How to follow a TSP fund without a ticker
- After the close: check the TSP share prices page or tsp.gov's share price history for each fund's price.
- During the day: watch the index, such as the S&P 500 for the C Fund. There's no live TSP price, so the fund's own number arrives only after the close.
Common questions
What is the ticker symbol for the TSP C Fund?
The C Fund has no ticker symbol. It's built to match the S&P 500 Index, so public S&P 500 funds such as IVV and VOO use the same index, but they're separate funds.
What is the ticker symbol for the TSP I Fund?
The I Fund has no ticker symbol. It's built to match the MSCI ACWI IMI ex USA ex China ex Hong Kong Index, which leaves out China and Hong Kong.
Is there a C Fund equivalent ETF?
ETFs that use the S&P 500 Index, such as IVV and VOO, hold the same kind of portfolio as the C Fund. Returns won't match exactly, because fees and pricing differ.
Can I look up a TSP fund on a brokerage or stock app?
Not as a listed security, because TSP funds aren't traded on an exchange. TSP share prices come from the TSP, and tsp.gov publishes the price history.
Why don't TSP funds trade on an exchange?
The funds exist inside the TSP, a retirement plan for federal employees and members of the uniformed services. Money goes in through the plan at the day's closing share price, not through a market.
