NEW YORK ( TheStreet) -- There are some great stock plays coming out of Brazil, Jim Cramer said during his Stop Trading! segment on CNBC. Ahead of the Olympics, Cramer announced that he would buy a steel and mineral company. His picks are Gerdau S.A. ( GGB) and Vale S.A. ( VALE). Cramer says Gerdau, a low-cost producer of steel, is a great play on Brazilian infrastructure and would own this stock right through the World Cup and the Olympics. It has a $15 billion budget for the Olympics. Cramer owns Vale for his charitable trust. When it comes to integrated oils, however, Cramer isn't getting behind companies like Petroleo Brasileiro ( PBR). One of the biggest initial public offerings of the year came from Banco Santander Brasil ( BSBR). Despite the deal garnering $2.02 billion, Cramer says you don't want to own the company. Instead, Cramer says to look to its parent, Banco Santander ( STD), which he says is really in control. "It is one of the most responsible lenders in the world," he said.
