Anyone can be permanently bearish (it works both ways - the permanent market cheerleaders are just as bad in reverse) and then go on CNBC and tell everyone they correctly called every recession or bear market.
Typically these people have called 176 of the last 8 recessions.
There are plenty of fund managers out there that make some when its a bull market and make some in a bear market, they dont tend to go on tv and talk their book though.
