There are four major forces that influence the overall climate for stocks. These are: economic fundamentals, stock valuation, monetary policy and psychology.
Economic fundamentals (namely classical principles) represent the broadest long-term force affecting the market. Stock valuation is an intermediate force (roughly one year) and monetary policy is a shorter-term force (several months). Psychology or technical forces represent the shortest and most immediate pressure on stock prices at any point in time.
To understand the pressures on stock prices it is helpful to quantify the effect of these forces. I assign a value from 0 to 10 for each of these forces, where zero is an extreme negative, 5 is neutral and 10 is Bo Derek positive. These ratings are updated weekly and sent to subscribers.
