Jim Rohrbach, a top timer for over three decades -- and one who successfully side-stepped the recent decline -- just issued a buy signal for the NYSE in his Investment Models.

"I am a mechanical investor. Each day my proprietary RIX indicator converts the stock market action into numbers that represent the trend of the market. These numbers then trigger buy or sell signals for the NYSE and the Nasdaq. It's that simple.

"And because the readings are mathematical, there is subjective interpretations. No guessing, no predicting, and no anticipating. I never try to out-guess my strategy. I act on every signal, without question, because I know that over the past 36 years I have caught every major up move and I have avoided every major decline.

"Big up moves do not come very frequently, so you have to take advantage of it by staying in the market until it peaks and turns down. I am going 100% invested today. I believe that the market can give us a nice up move from here.

"We could make some money on this move. But, as always, it's up to the market to do what it wants to do, and there is no way to predict that outcome. The best we can do is go with the trend and act on every Signal.

"I know from past experience that we will catch the bulk of any big up move, and we will avoid most of any major down move. Our recent experience proved that. Anyone who tells you they can do better than that is just blowing smoke.

"Meanwhile, to assess what the market is doing, we follow the daily readings of the RIX that mathematically measure the trend of the market every day. We can watch those numbers and see them move with the market.

"I will personally be investing in ProFunds Ultra Bull Fund (ULPIX). This fund is leveraged at 2 times the S&P 500. Of course, you have to make your own decisions on what investment vehicles you prefer.

"If you traded ULPIX along with our RIX signals you would have taken a 20.1% profit in 2007. For the year, we were out of the market for 131 days (4 1/2 months) in 2007. We were out most of the time when the market was in severe drops and you can't put a price tag on the good feelings you get, watching from the sidelines while others are going through a very emotional experience."
