The short version

Wednesday was a broad pullback for stocks. Every TSP fund except the G Fund closed lower, and the three stock funds all dropped more than 1%. The G Fund edged up 0.01%, as it usually does when the rest of the board is red.

How the TSP funds moved

C Fund: down 1.36% to $106.2748. That matches the S&P 500, which fell 1.36% in the data I have. The fund is down 2.2% over five days and 3.16% for the year.

S Fund: down 1.27% to $99.0037. It follows the Dow Jones U.S. Completion index, which covers mid- and small-sized companies outside the S&P 500. It is down 1.85% over five days and 2.62% for the year.

I Fund: down 1.25% to $57.2340. It tracks MSCI ACWI ex-US ex-China. The five-day loss is 2.11%, but it is still up 2.15% for the year. It remains the only stock fund in positive territory for 2026.

F Fund: down 0.36% to $20.9080. It follows the Bloomberg U.S. Aggregate bond index. Yields rose, and bond prices move the opposite way. The fund is up 0.23% for the year.

G Fund: up 0.01% to $19.7634. Its return is tied to a Treasury rate, not to market prices, so it doesn't swing with stocks. It is up 0.87% year to date.

Drops over 1%

Several funds crossed that line:

  • C Fund, -1.36%
  • S Fund, -1.27%
  • I Fund, -1.25%
  • L 2055, L 2060, L 2065, L 2070 and L 2075, all -1.30%
  • L 2050, -1.10%
  • L 2045, -1.03%

L Funds: more stocks, bigger dip

The L Funds blend the five core funds, so their losses line up with how much stock each one holds. L 2030 fell 0.77% and L 2035 fell 0.89%. L 2040 dropped 0.96%. The longest-dated funds, 2055 through 2075, lost 1.30%, close to the C Fund's drop. L Income, the most conservative blend, slipped 0.37%, about what the F Fund did. The five-day losses run from 0.54% for L Income to 2.1% for the longest-dated funds.

What moved IRA index funds and ETFs

The index and ETF figures I have are labeled as prior session close, and they line up closely with the TSP moves.

The S&P 500 fell 1.36% to 6624.7. The Nasdaq Composite lost 1.46% to 22152.42. The Dow Jones Industrial Average dropped 1.64% to 46225.148, the weakest of the three. Vanguard Total Stock Market ETF (VTI) fell 1.38% to $326.02, in step with the S&P.

Vanguard Total International Stock ETF (VXUS) lost 1.73% to $77.25. That is a bigger drop than the I Fund's 1.25%, and the two follow different benchmarks.

Bonds slipped too. Vanguard Total Bond Market ETF (BND) fell 0.41% to $73.68. The 10-year Treasury yield rose 1.36% to 4.259, which is roughly 6 basis points. A higher yield pushes bond prices down, which fits the F Fund and BND declines.

What it means for your plan

A 1% to 1.5% drop in stocks is uncomfortable, but it is not unusual. One session says very little about a plan built over years or decades. If your contributions and allocation match your goals and your timeline, a day like this doesn't change that. The G Fund's steady day and the I Fund's year-to-date gain are reminders of why people diversify. This is a general recap, not personal advice, so check your own situation before making changes.
