Agree 100%...
Of course there needs to be a mix and shorter term opportunities like RSH are not what your portfolio should be based upon fully at all. Never invest what you aren't willing to lose at a 100% loss.
Excellent point, no one wins 100% of the time and anyone who says they do, well they should write a savvy investing book on it.... 70% has been an acceptable level and when it hits above, it's just dessert. :-D Trick is to let the winners run out and cut losses quick.
This place is a haven for sour grapes of those who bet more than they should on a turd and came up short. ;-)
I'll look for Taleb in audio, only thing I can read now are Disney books without complaints from the bleachers here.... :-)
Have a great day!
