Upon inventing IBM’s first spread sheet program at age 27 I developed my first stock price forecasting model using this software. I tested my model's performance on a database of over 50 stocks with 15 years of historical daily price and earnings data. The model was statistically significant in picking short-term price bottoms. Since retiring from a career in high-tech product management in 2009 I’ve developed those models further. I now have market direction models for the major North America markets that incorporate public and proprietary metrics that have proven robust in extensive performance back-testing and sensitivity analysis. I am a member of the Canadian Society of Technical Analysts.
