This presentation introduces the core “Financial Physics” model. The key factors include Real GDP, Inflation, Nominal GDP, Earnings Per Share (EPS), and P/E Ratio. Since Real GDP has been relatively constant over extended periods of time and all other factors are driven by inflation, a primary driver of the stock market is inflation — as it trends toward or away from price stability. Given the current state of low inflation and the likelihood of it either rising (inflation) or declining (deflation), P/E ratios are expected to decline, in general, for a number of years. As P/E ratios decline and EPS grows, the result will be another relatively nondirectional secular bear market.
