On today's STOP TRADING segment on CNBC, Cramer had some things to say about Latin America following Venezuela's Hugo Chavez laying the groundwork to steal back the national telecom and oil infrastructure into government ownership after the prior governments privatized these. He said you are a pig if you are staying in Latin America because they can steal back your company.

Cramer said he still likes Apple Computer Inc. (NASDAQ:AAPL) but he said he thinks the iPhone price seems high and he wants to look at more information before getting behind it. This was his #2 Growth Stock for 2007 last week.

On KSwiss (NASDAQ:KSWS) and Abercrombie & Fitch (NYSE:ANF), he said he agrees with CNBC's previous guest, Olsteen, about inventory situations and is cautious on the names there.

Cramer was asked about Nordson (NASDAQ:NDSN), a thin volume company. He said its dividend helps make it safe and it's what he called a "chicken cyclical."

Cramer said that if you liked China Life (NYSE:LFC) when it was up 20%, well now's your shot at minus 10%.
