NEW YORK ( TheStreet) -- Earnings winners continued on Thursday with more beats than misses. But this week we also observed that all stocks are not created equal in an extremely overvalued market. Stocks that missed earnings estimates or offered cautious outlooks can get their share price severely cut in a move to behind the investor woodshed.I did not realize that potash prices were controlled by cartels similar to OPEC in the oil market. This week companies that produce fertilizer took a major hit on a glut of the ingredient called potash. Wholesale potash prices have been falling since mid-2009, so when a dominating potash cartel collapsed, the industry got hit hard on a potential price war. The three names I profile today were taken to the woodshed on Tuesday on this news.
