I'm getting a lot of inquiries about the price given to the I-fund yesterday. A few things to keep in mind:
1) The EAFE Index that the I-fund tracks closes before noon ET.
2) The EFA price at the bottom of tsptalk.com is NOT the I-fund. It is an ETF traded on the U.S. market that is supposed to track the EAFE Index and so we use it for some intraday guidance, but since it is traded like a stock, the price is where the buyers and sellers agree on a price. So while the EAFE is closed, traders are still speculating on a price.
3) The TSP has to come up with a price. This where it gets tricky because they have to decide whether to use the actual EAFE number, or to add / subtract "fair value" based on what's happen in other markets after the EAFE has closed.
The I-fund was given a loss of 0.27% on Friday.
The EFA had a gain of 1.11%.
The EAFE Index actually closed down 0.28% on Friday.

The EAFE and the TSP will likely adjust on Monday, you'll see.
