Arch Crawford attempts to time the markets using astrology. The Hulbert Financial Digest follows his newsletter, and Hulbert rates it highly at times.
Crawford sees turmoil around the corner in the stars. On Sunday, August 1 he projects a Cardinal Cross. Here's how he described it in his January 2010 newsletter:
"[There is] a high probability that World Markets will Crash again during 2010. The point of greatest exactitude of the general ‘meanness’ will show itself in late July and early August. During that period Mars will conjoin Saturn, both opposing Jupiter conjoining Uranus (you can joke all you want, but THIS is no laughing matter). Pluto will form a square angle to all four, making a T-Square pattern of extreme animosity. . . .
We will do everything but guarantee you that stocks will crash worldwide within three months of August first (that is between May 1 and November 1). It is expected that technical market analysis of data generated by current market action will assist in pinpointing most danger/opportunity as critical moments approach."
Crawford notes that, following the Cardinal Cross on August 1, there will be a Full Moon on the Fall Equinox (September 22, 2010) and a Total Lunar Eclipse on the Winter Solstice (December 21, 2010), both exceedingly rare events. He says "We expect the depth and scope of dislocations during this period to exceed anything we have ever witnessed."
