Log Spirals In The Stock Market by William T. Erman

Log Spirals In The Stock Market by William T. Erman The basic mathematical characteristic of the log spiral is that even while increasing or decreasing in size, the log spiral remains constant. This is also true for rectangular spirals, the parameters of which are determined by their related log spirals. Many major market moves share the properties and predetermined progression of these spirals, indicating the close correlation between multiple manifestations of the ordered form of nature and the architecture of markets themselves. Three important turning points between 1974 and 1978 have influenced the growth pattern of many subsequent major and minor market moves, up to and including the July 20, 1998, peak and the September and October 1998 lows for the Dow Jones Industrial Average (DJIA) and the Standard & Poor’s 500, respectively. Here’s how the triangle in Figure 1, which connects the 1974 low for the S&P 500 index with the 1976 peak and 1978 low, have influenced these subsequent market moves. The triangle seen here connects points 1, 2, and 3 from Figure 2. The points in Figure 1 and 2 are those moves analyzed in this article.
