Hey Guys,

If you're talking about the TSP fund, I believe 2 Interfund Transfers are allowed per month. And after that, you can do another IFT to the G fund in the same calendar month. They made this rule effective May 1, 2008. Unless there's a revision to this rule that I don't know about, this rule still stands. See: https://www.tsp.gov/PDF/bulletins/08-4.pdf. Page 1 & 2 explain it pretty well. When moving lots of shares around, twice per month is a lot more flexible than one.

One time I called into a radio show called the Mutual Fund Show to ask about swing trading strategies using the TSP. The host, Adam Bold, pretty much chewed me out for even THINKING about trying to time the market. How dare I! .... As you can probably tell, I don't listen to that show any more.
