The casino stocks are kind of like the tobacco stocks, Jim Cramer told a caller on his "RealMoney" radio show Wednesday. They're both vices that people can't stay away from, he said. Cramer said he can't be against someone who wants to ring the register on Las Vegas Sands ( LVS) since it is up so high, but even if it came down three or four points he said he would be tempted to pick some up, not throw some away. Cramer told a caller to wait until RadioShack ( RSH) goes to $15 to buy half, and then buy the other half when the company announces what he expects will be a pretty bad quarter, he said. RadioShack was recently at $16.75. When a listener inquired about Crystallex ( KRY), which has a giant gold mine in Venezuela, Cramer said to hold it for now, then buy more when it goes down to $2.50 and ring the register at $4.50 to $5. Although MasterCard ( MA)is under a lot of pressure and has been hurt today, Cramer said he is not giving up on it. Deutsche Bank has issued negative reports on MasterCard, but he said he is not backing away from it. When a caller asked about Quest Diagnostics ( DGX) Cramer said it is a keeper here in this economy, and he told a separate caller who inquired about H&E Equipment Services ( HEES), that he likes the company, and with the probability of three up and three down, it might not be the time to pull the trigger on this stock yet. Hershey ( HSY), like soaps, soups and cereals, is one of the few companies that will do well in the current economic slowdown, he said. It is a consumer staple that people will continue to buy and use whether the economy is good or not, he said. Cramer told a caller that Automatic Data Processing ( ADP) should be making more money and suggested swapping out of it and getting into Hershey, Quest Diagnostics or Altria ( MO), which he owns for his charitable trust, Action Alerts PLUS . He also suggested holding on to Schering-Plough ( SGP), which he owns for his charitable trust, Action Alerts PLUS , with a long-term perspective, since the company is in the midst of a turnaround and could make a lot of money on the upside. Bristol-Myers ( BMY), which he also owns for his charitable trust, Action Alerts PLUS , is another drug manufacturer which he believes has a limited downside, he said. Cramer told a caller to swap out of insurer American International Group ( AIG), even though it is at its 52-week low, and suggested MetLife ( MET), Prudential ( PRU) or Allstate ( ALL)instead. "Allstate got smart and stopped writing aggressive insurance in areas that are hurricane prone," he said. He warned a listener to be careful with Carpenter Technology ( CRS), as it's been going down for no reason and suggested taking a little off the table.
