New allocation: 100%F Fund
IFT date:31May 05
Moving to 100%F Fund as of COBTuesday,31May 05.
The stock timing system gave a sell signal as of27 May 05.
This past move was frustrating. The timing signal to re-enter stock funds at the close of 10 May was good. Unfortunately,the I Fund didn't cooperate. The C and S Fundshave donewell, as did most other stock funds. In fact, other EAFE-based funds such as the EFAand the Scudder EAFE mutual fund (BTAEX) have even had slight gainsduring this last signal. We do have one more day before the IFT,and a positive return for this signal is still possible. (The loss has been small so far, and the I Fund could certainly swing strongly eitherdirection on Tuesday.)
Some people question investing in the I Fund at all since its daily valuations seem so quirky. The folks at Barclays do these strange valuations to prevent"time zone arbitrage." Most (all?) other fund companiesdo this, too. At leastBarclays doesn'tadd redemption fees like Vanguard:

A few otherthoughts:
1) Despite the unpredictable daily (and perhaps even weeklyand monthly) valuations, the I Fund has been the top performing TSP Fundfor the lasttwo years. This isn't surprising, since international funds badly underperformed U.S. funds during most of the 1990s. When one asset class outperforms another for a long time, the tendency is for the classes to"revert to the mean," as statisticians say. This just means the underperforming class is likely to play catch up for awhile,bringing its relative returns back to normal. If you ignore the I Fund, you may continue missing out on a"mean reversion" period of strong performance.
2) The I Fund's unusual valuations should "wash out." Sometimes you'll get burned like I just did.Other times you'll catch the I Fund in an unusually strong period where valuationsseem to go your way. We've seen a few such periods already this year. Over the long-term,the times you get "burned" and the times you get "lucky" should be about the same if you invest with a consistent plan.
3) I did some backtesting of my system with a blend of the 3 stock funds instead of100% allocations to the strongest fund. The "100%" version I usehad higher returns over time, so that's why I use it. There were times when a 3-fund blend worked better, but the 100% concentration had enough strong periods to warrant its use. This was especially true in the late 1990s, when the C Fund dominated. (Too bad there wasn't a NASDAQ index fund back then!). It has also been trueduring thelast 4-5 years when the S and I have taken turns in the top seat and consistently outperformed the C.
