Weyerhaeuser ( WY) is the biggest and best lumber company in the country, Jim Cramer told a caller on his "RealMoney" radio show Thursday. It is at or near its 52-week low because the country is experiencing a housing glut, he said, adding that if we have a severe hurricane season that could change. However, Weyerhaeuser has one saving grace, Cramer said -- that it has a dividend which has a 4% yield. The stock has come down a lot, and he said he would not be ashamed or scared to buy Weyerhaeuser right now. Cramer believes Nabors ( NBR), which he owns for his charitable trust, Action Alerts PLUS , is finished going down and advised a caller not to lose heart. Business is good and natural gas is not going lower, he said. "It is way too cheap compared to other drillers," he said. Amazon.com ( AMZN) is too expensive, Cramer told a listener. He said he won't own it because it's too likely to go down. Bancolombia ( CIB) is the best bank in Colombia, which is a country that is pro-U.S., he said. However, the problem is that this market is so risk-adverse, that they are not willing to invest in a company that is located in Colombia -- even if it's good. Bancolombia could go back down to $20 before it rallies it again, he said. It could go three points down and five points up, he said. It was recently at $23.45. "We don't want Ford ( F)," Cramer told a caller who asked about it. Instead, he said General Motors ( GM) is way ahead of Ford in terms of restructuring and has made its balance sheet better. He recommended swapping out of Ford and into GM. CB Richard Ellis Group ( CBG) is a huge commercial real estate company, which is a sector that is en fuego right now, Cramer said.
