"One set of stocks I perpetually get asked about is

Sirius Satellite Radio

(SIRI) - Get Report

and

XM Satellite Radio

( XMSR)," Jim Cramer said on his

"RealMoney" radio show Thursday.

Sirius has become one of his top three favorite speculative stocks. It has joined the ranks of

Rite Aid

(RAD) - Get Report

and

Level 3 Communications

(LVLT)

, Cramer's other favorite speculations.

Clear Channel

(CCU) - Get Report

has a $17 billion market cap, and yet it has no growth, Cramer said.

"On Wall Street we care more about growth than assets," he said. "On Wall Street we want the kind of company Mel Karmazin has with Sirius."

In a high-growth company, what Cramer looks for is free-cash flow. For its fourth quarter and many more quarters, Cramer believes that Sirius will have positive free-cash flow.

In addition, the acquisition costs are coming down at Sirius, and "it could have hundreds of thousands in advertising revenue in the next few years" and more subscribers, Cramer said.

"If you're in XM Radio, you should sell it because Sirius is the main play in this group," he said. "Sirius is not worth selling, not one bit. Sirius is worth buying."

Exxon Mobil

(XOM) - Get Report

has been a "consistent gainer for the last three years," and people are starting to take notice, Cramer told viewers.

The company has a lot of oil in the ground and doesn't miss its quarters, he said.

As "Exxon has been so consistent in this period, it keeps going higher," Cramer added. "If the oil stocks fall out of favor for a while, Exxon is the one you want to buy."

It is now the "anointed oil" company and the one Cramer is focused on.

For the longest time there was a belief that natural gas was coming down, so companies exposed to it went down. But now that natural gas has started to go up, it is taking

Halliburton

(HAL) - Get Report

up with it, Cramer said. He owns the company for his charitable trust,

Action Alerts PLUS.

Halliburton is a stock that market players should look at, he said.
