Jim Cramer's Stop Trading! Toyota's Sly Tout

If you want some reasons to buy Toyota (TM Quote), check out an upgrade on Ford (F Quote) that was issued today, said Jim Cramer on CNBC's "Stop Trading!" segment Tuesday.

Morgan Stanley's Jonathan Steinmetz upgraded Ford to overweight from equal-weight and set a price target of $9.50, based in part on its ability to fund planned restructuring.

Cramer, however, panned the upgrade as a "dice roll" and said the real takeaway from the report was Toyota's strong position in the market. "This is a Toyota sheep in a Ford's clothing. ... Every single statistic in this document has 'Toyota Motor' at the top."

Cramer also warned about the dangers of the emerging markets and the important of being selective, particularly in light of the difficulties in the Thai market today after the military imposed restrictions on that country's financial markets. Only two types dabble in emerging markets: hedge funds using leverage to "shoot out the lights," and "jokers" who are essentially gambling.

"I don't play it," he said. "I want to be able to sleep at night."
