“Nothing epitomized momentum like the fertilizer stocks. Somehow this totally commoditized industry caught the attention of everyone, as a combination of ethanol demand and worldwide food crisis gave it the hue of a Google (GOOG) or an Intel (INTC) from years past, coupled with a long-term thesis that felt as though rising prices could always be justified. But then the underlying product, corn mostly, got crushed, and the economics of the product changed. Amazingly, few people wanted to believe this trend, even though the whole case for the endless price rises taken by Potash (POT), Agrium (AGU) and Mosaic (MOS) stood on the issue of higher grain prices. Once that prop was removed, it seemed fairly obvious that the stocks had had it. But in a testament to the gods of momentum, when I pulled these stocks and put them in the "sell block," something I do every Thursday on "Mad Money," the viewers went nuts and considered in an ultimate betrayal. The anger astonished me, as I had been for these stocks for years, and the gains were stupendous. Some were angry that I had failed to call a top - frankly, that was just way too hard. Others were angry because the companies had endlessly talked about how inventories for food worldwide were the lowest they have ever been. To me, there was nothing to this one, corn down, and I didn't care where I said to sell 'em, because the trick to commodities is to rack up a big gain and then say "sayonara," not at the peak of the stock but at the peak of the end market. That's the same case for steel, where I missed the top until China stopped ordering. People have to recognize that when you trade commodity stocks in this era or any era, there is a time to buy and a time to sell. You buy when prices are going up and the end-market takes the pricing. You sell when the end-market balks, not when the companies lower pricing. The latter will always get you out too late.”

From a recent Mad Money show: "The price of steel is coming down, so there's no way Wall Street will buy into that. Wall Street is being ridiculous, but that stock needs to go lower before it can be bought."

From a recent Mad Money show: "I have to tell you, I'm seeing some incredible prices out here. I need to see the Boeing strike over though before we can buy in."

From a recent Mad Money show: "I think Comcast has bottomed and cable is starting to come back up. I think under $20 this one is a buy!"

From a recent Mad Money show: "This is a stock I've liked for a long time. This is one of the few tech stocks I want to own, along with Apple."

From a recent Mad Money show: "Very well run but I'm not recommending any brokers. I'm done recommending brokers and hurting people. "

From a recent Mad Money show: "I like the guy who runs it, but he has disappointed, disappointed, disappointed and I'm not recommending it."

From a recent Mad Money show: "I do not want to recommend this one, either. Obama hates coal so I have to as well."
