In this In It To Win It interview, the host asks Rick Rule about my team's work on the pre-production sweet spot (PPSS) (starting at 17:10 and ending at 21:20). This is the first time I've heard Rick actually describe the back-testing and spot-checking he did. If you've ever thought my findings are too good to be true, well, so did Rick… and he could find no flaw. My latest research results on this strategy are available as a free download on The Independent Speculator website.
