Why the disparity between the C fund and S&P today?

[Yankee6]

I understand why the I fund differs from the EFA index, but the C and S&P are always VERY close to each other. How the heck did the S&P do 2.9% today and the C fun 1.9%? Of all days to lose out on gains this is really bad.

Im guessing they also calculated the losses from yesterdays markets in the numbers as well.

Exactly, the TSP was closed yesterday, check the "I" fund!:suspicious:

From my tracking, the TSP C-Fund lost approximately -1.04% on Monday.
On Tuesday the C-Fund gained +3.03%. This is assuming that all +/-FV
stayed the same as it was on Friday. The C-Fund was simply reflecting
the outcome of Mondays loss and did a catch-up.
