I don't know the Sherman guy, but if he made that prediction, his opinion should be disregarded IMO.
DJIA up 35% in twelve months? Next year? I wish there was some way I could wager him. It would be the closest thing to to a "lock" that I have witnessed in my 38 yrs in the business.
I would also bet plenty that Stein did not make that prediction or perhaps he misheard what was said.
Most all predictions are S&P up 11% minimum, DJ at 15000 before year end and overseas seeing records.....Looked WAY back for this. Dow at 12,500, S&P up 18.05%, and EAFE way up. Some predictions close, some spot on. Happy New Year.
