he's a crass loud mouthed buffoon, flapping his hands around on TV like some mutant chimp. Although that is reason enough. No... I dislike him because he's an irresponsible (and dishonest) huckster IMO. It's hard to measure the amount of money he has lost CNBC viewers over the years with his reckless trading advice? But I would bet that it is considerable.
Usually when Cramer says sell one could make money by buying. CNBC IMHO should not have anyone talking their book but this happens all day on the network. CNBC must charge a fee for this IMHO for them to have so many doing this. It is not just Cramer although Cramer is the loudest of the lot. This is one reason to do your own research into an investment you may want to purchase. Don't buy something without understanding the fundamentals of the investment. All JMHO.
