 | Hi, in O'Shaughnessey's book, what works on wall st, one very simple way to pick winners was to buy stocks with a PSR <1. Since his analysis was done on wall st data, it would be foolish to assume it works on our market. Has anyone here bothered to check out this simple method using historical PSR data? I'd like to but there is no provider who I can find with enough data (say 25 years) and dead company listings! They all seem to cater for chartists.
