Model 2.0 was fully implemented at the close of Friday, September 9, 2006. The above data was generated with version 2.0.

I am now working on Model 3.0 which I am now implementing (Sept 17’06). Both AAPL and DIA end up with Model 3.0 being identical to Model 2.0. In other cases the ‘tuning’ is different and it may not be the case.

On Sunday, Sept 24’06 I implemented version 3.5 for AAPL and DIA.

On Oct 10’06 I started implementing version 4.0.

On Oct 22’06 I discovered a ‘small’ typo in an equation that generates the tabulated data for AKAM, AAPL, GOOG and DIA. The above table has the correction incorporated.

Please Note This Disclaimer:  The above results are generated from a mathematical model. It provides some insight into what may be expected in the short term (2 to 4 week cycles).  While reliability is of highest importance, life is such that the model is not always correct. Neither is past performance necessarily indicative of future performance. Stocks, markets, and options can change greatly in value in short time spans because of unpredictable events. The model cannot foresee such events. When they happen, the model’s performance will be poor and in some cases - wrong. The user is advised to be cautious and to try to couple the results for individual stocks to those for the market averages.
