I watch his show everyday, but I think twice before I buy what he says. I have seen him recommending stocks that has already gone really up, and If you buy there you will lose for sure.
However, I have got lots of knowledge from his book and just by watching his shows. The bottom line is just don't buy or sell based on what he says, do you research very well and make your own judgment.
U stock is really volatile now and should stay away from all U stocks for a while. I don't think this sector will die, but it will take a while to recover from this disaster.
He hypes stocks up when they hit the top to short them down and when he wants to own them like uranium stocks he hopes people will not buy them cause he can't short it down tomorrow cause the CB was tripped. So if the stock stays down he can short it to a price to buy in for his charitable trust.
On a side note he also said buy Jones Soda at 10Bucks then again at 17bucks and then let me see where it is today... JSDA is at 1.29 and was much lower I waited to buy it in the 30cent range then sold at a buck short term gain.... BPOP just recommended by cramer at 3.18 is at 3.00 now and I actually have liked that stock since i bought in a year ago at 2.86 average. Can go on and on but if he said don't buy means he wants in this industry and is worried he can't short it down and make money on the ride down and then up.
Cramer at least provides some education in addition to entertainment and his fundamental approach make sense for people turned off by technical analysis metrics. But his 'diversification' doctrine in completely wrong in today's markets. Today's markets are all so interrelated, because everyone has been preaching the exact same diversification religion for so long, that it doesn't matter anymore. Today all market segments and almost all asset classes go down in sync as the crash in 2007 has shown us clearly.
