The negativity in the market is reaching a fever pitch, said Jim Cramer on his
"RealMoney" radio show Wednesday. That's usually a sign the market is nearing a bottom, he said. Cramer recommends checking your emotions and taking advantage of the negativity to do some buying Thursday or Friday, particularly in tech, he said. After Thursday, Cramer believes that it will be wrong to be short. It has become way too easy to be short, he said. Commenting on Microsoft ( MSFT), Cramer said the company is a growth stock priced like a value stock. In fact, Rich Pzena, fund manager of John Hancock Classic Value, of whom Cramer is a big fan, has been buying Microsoft for his fund, he said. "You should own it, too," said Cramer. JDS Uniphase ( JDSU) is a "changed and fixed company," said Cramer. Although it takes guts to buy JDSU in this environment, this is when you have to step up to the plate, said Cramer.
