It seems everyone is focused on Apple ( AAPL), but if you're serious about making money, consider some stocks currently out of favor, Jim Cramer told viewers of his "Mad Money" TV show Thursday.

"I want to look at companies that have failed and what management has and can do for them," Cramer said. "That's why its time to look at Sony ( SNE)," while everyone is focused on Apple.

These two stocks are "polar opposites," he said. Sony looks like it can't do anything right, while Apple can do no wrong. Sony is being "written off," which is why Cramer believes that it's time to sit down and take a good, hard look at it as a value stock.

Sony is a company which is worth $45 billion, but it should have $70 billion in revenue, he said. Meanwhile, Apple is worth $82 billion and is supposed to have $23 billion in revenue.

Despite being a "revenue machine," Sony is still unloved, Cramer said.

Looking at these numbers, anyone can see that Sony is too cheap and would obviously be worth more if it was to break itself up, he said.
