I'm in the stand-by category. Right now, I'm at 98% G, and I'm willing to miss the boat should the I fund take off.
As Rumsfeld says "there are many unknown unknowns" in the equation for me to jump in with 2 feet. The volatile DOW (400 pt swing in the past 2 days alone), the uncertainty with bank failures, the collapse of the housing market, and the destruction of many investment banks in the past year leave me with far too many x's, y's and z's to make any statement either way. The additional question of the international dollar market also causes me some concern. Interest rates have been kept at unnaturally low levels as well. At the same time, banks are failing left and right.
Right now, all new money is going into the I and the long-term funds, so I'm not completely risk-averse. The long-term strategy would indicate accumulation over time, but I'm not willing to endorse any of the investment sectors right now. The EAFE is trading at the low 50's, but did get all the way down to the low 30's just a few months ago.
That being said, when I dumped out of I in mid-September, it hasn't changed an enormous amount, from that point. Unlike October of last year.
Your call. Your money. Your risk.
