The Thrift Savings Plan closed out 2012 with strong showings by nearly all the funds — both for the month of December and the year.
The C, S and the I Funds posted the largest gains last year. The C Fund, which matches the performance of stocks in the S&P 500, was up 16.07 percent. The S Fund, which tracks stocks not included in the S&P 500, posted gains of 18.57 percent. And the I Fund, which tracks a suite of international stocks, was up 18.62 percent at the end of 2012.
That’s a far cry from last year, when both the S and I Funds posted negative returns for the year, and the C Fund saw only modest gains.
The G and the F Funds posted more modest gains for the year — 1.47 percent and 4.29 percent, respectively — both below last year’s levels.
