On Wednesday's episode of "Mad Money," Jim Cramer spoke with Airgas (ARG - Get Report) CEO Peter McCausland. In October, Cramer named Airgas a sell, but he said he was wrong, since the stock was up 37% since.
Cramer said last night that he's "sticking" with McCausland. On Thursday, Airgas closed down 25 cents to $42.72.
Cramer's Wednesday "Tech Spec" picks was Cadence Design Systems (CDNS - Get Report), which he said could follow Taiwan Semiconductor's (TSM - Get Report) 27% rise since he'd last recommended that stock.
Cramer said Cadence doesn't have much competition in its business of making tools that help create smaller, faster microchips. He said its management made big mistakes in 2008, but that's all in the past, and the company has a new chairman and CFO who's been buying shares.On Thursday, Cadence added 28 cents, or 5%, to close at $5.88. Taiwan Semiconductor gave up 66 cents, or 6%, to close at $10.39. In the "Lightning Round" segment, Cramer he would buy Waste Management (WMI). He liked the stock's 4% dividend. Waste Management closed down 30 cents, or 1.1%, at $26.65 on Thursday. Cramer also said that DryShips (DRYS - Get Report) is a speculative play in its group. He recommended Frontline (FRO - Get Report) and Nordic American Tanker (NAT - Get Report) instead. On Thursday, DryShips closed down 66 cents, or 6.2%, at $10.04. Frontline dropped 90 cents, or 3.7%, to $23.73, while Nordic American Tanker was down 50 cents, or 1.4%, to $36.22.
