Crammer is a mo-mo guy. When momentum is up, and the stock has already run up, he' s "buy, buy, buy!". When the same stock has already sold off 50% and is near a bottom, he's telling people to SELL!.
He is the opposite of a value investor. In fact, he is not an investor, he is a short term trader, and is costing a lot of average folks lots of their hard earned money. He has been caught switching his call overnight, catching these poor suckers on the wrong side of his trade. He's a clown, but a mean one.
Cramer is an interesting guy but buying stock based on his recommendation means you're not paying attention. He is a TV star. They should cut his tv show to 15 minutes of commentary and skip the stock picking advice, it's not very good to say the least.
