Updated from 9:22 a.m. EDTStocks slipped on Monday after a choppy day of trading as investors remain uncertain about the length and depth of this recession. Technology stocks were the biggest drag on the markets, led by IBM ( IBM) and Hewlett-Packard ( HPQ). Trading continued around 12-year lows despite news of large mergers and acquisitions. Drugmaker Merck ( MRK) announced plans to acquire Schering-Plough ( SPG) for $41.1 billion. The deal is expected to widen Merck's pipeline of new products and expand its international presence. Meanwhile, trading was suspended on Dow Chemical ( DOW) and Rohm & Haas ( ROH) late Monday while the two companies tried to work out their $13 billion merger in court. With this in mind, we thought we'd take a look at some of the stocks people have been searching for on TheStreet.com, including Caterpillar ( ROH) and Tupperware ( TUP), and see what Jim Cramer's had to say about them.
