Buy Freeport-McMoRan (FCX), Jim Cramer said on CNBC’s “Stop Trading!” segment Wednesday. Cramer currently owns FCX for his charitable trust. He likes the company for a play on increased copper demand from China and the housing boom that is happening right now in India. Cramer said investors should look to buy gold for a trade. He thinks the yellow metal is heading to $1000. He told investors to avoid Thornburg Mortgage (TMA). “Stocks don’t get under a dollar because you want them there. I would be careful,” he said. Moving on, Cramer pointed out that Dow Chemical (DOW) is moving a lot of its business overseas until the U.S. government does more to make America more business-friendly. Cramer likes shares of DOW on the news. Finally, Cramer said he thinks American International Group (AIG) should be investigate by the Securities and Exchange Commission for statements the company made in 2007.
