Among the largest forces that strike stock prices are inflation, interest rates, bonds, commodities and currencies. At times the stock market on the spur of the moment reverses itself followed typically by published explanations phrased to suggest that the writer’s keen observation let him to predict the market turn. Such circumstances leave investors somewhat awed and astounded at the infinite amount of going along factual input and infallible interpretation needed to avoid going against the market. While there are continuing sources of input that one needs in order to invest successfully in the stock market, they are finite. If you contact me at my web site, I’ll be happy to share some with you. What is more important though is to have a robust model for interpreting any new information that comes along. The model should take into account human nature, as well as, major market forces. The following is a personal working cyclical model that is neither perfect nor comprehensive. It is simply a lens through which sector rotation, industry behavior and altering market opinion can be viewed.
