A recent academic paper (Batchelor and Ramyar, 2005) investigated the frequency of price and time ratios attending adjacent movements in the DJIA (“retracements”) as well as same-direction movements separated by an intervening movement (“projections”). Some comments from a practitioner may prove constructive. The study is valuable in demonstrating that price-filtered movements in the stock market do not generally relate by a Fibonacci multiple either to price retracements or to projections. It supports an observation dating from the first edition of Elliott Wave Principle (Frost and Prechter) in 1978: In discerning the working of the Golden Ratio in the five up and three down movement of the stock market cycle, one might anticipate that on completion of any bull phase, the ensuing correction would be three-fifths of the previous rise in both time and amplitude. Such simplicity is seldom seen. (1978/ 2005, p.133)
