Martin Armstrong was exact to the day on the last cycle date: 2/27/2007, when global markets experienced a mini-collapse and the Dow fell over 500 points! I moved all my money to fixed assets a few days later (3/2/07...when Dow was at 12114). Looking back at it...I didn't catch the market at peak (14000)...but it looks like a genius move right now, in retrospect. My 401k has not been depleted by the current crisis.
Armstrong predicts 4/23/2009 as the next significant cycle date. Note that significant can mean up OR down...good OR bad.
From the article...
"The issue of intensity seemed to revolve around periods of 51.6 years, which was in reality a group of 6 individual business cycles of 8.6 years in length. Back testing into ancient history seemed to reveal that the business cycle concept was alive and well during the Greek Empire as well as Rome and all others that followed. It was a natural step to see if one could project into the future and determine if its validity would still hold up. Using 1929.75 as a reference point, major and minor turning points could then be projected forward in time. For the most part, I merely observed and kept to myself this strange way of thinking. In 1976, one of these 8.6-year turning points was quickly approaching (1977.05). For the first time, I began to use this model expecting a significant turn in the economy back toward inflation. My friends thought I was mad. Everyone was talking about how another Great Depression was coming. The stock market had crashed by 50% and OPEC seemed to be undermining everything. I rolled the dice and stuck to it and to my amazement, inflation exploded right on cue as gold rallied from $103 to $875 by January 1980."
