Cramer is a ridiculous person, but the number of poor calls he makes and flip flops he has is because of the sheer number of stocks that he talks about, and the seeming conviction in his opinion either way. I bet that on any given day he makes a prognostication on about 200 different stocks. He also has a tendency to be a momentum chaser, getting really bullish on a name after it has already had a massive run. Inevitably a lot of those calls are going to look bad when they reverse, sometimes in spectacular fashion. This call about SVB is really similar to his infamous call about Bear Stearns 6 weeks before they imploded.
I have no evidence to support this, but I'm convinced he's doing some bidding for buddies he's still got in the business, helping them generate liquidity to get out of positions (or into them, when he's bearish on a stock but that's fairly rare). I bet that's what a lot of the touting of the stocks that have been up 50% in 6 weeks is about. It is just absolutely moronic behavior if what he says is a genuine representation of what he actually thinks, and I just don't think he's that stupid.
