That is the first and only one I’ve found.
There are so many making predictions every different day, in all different price ranges and time, I guess somebody should actually get it right now and then.
I would like to know if the same guy predicted the 2009 dip as well.
Hard to say.
I’ve read a lot about John Paulson, who made billions betting against subprime mortgages. He had a math savvy research guy (Paolo Pellegrini) who accessed a lot of data bases on the performance of mortgages, and drew conclusions that others either missed or were afraid to act on.
The oil stats seem similar, that there isn’t really “magic” data known only to insiders. But inertia is a powerful thing and it takes guts to bet against the herd.
