RealMoney Radio: Sirius Money

"You might want to sell packaging company Sonoco (SON Quote), take the losses and switch into an oil exchange-traded fund," guest host Gregg Greenberg told a caller on Jim Cramer's "RealMoney" radio show Monday.

When another caller asked about Ingersoll-Rand (IR Quote), Greenberg said that as the last gross domestic product report was "disappointing," the stock has fallen and has not been performing so well lately.

"If the economy picks up, then you'll see this stock do well," he said. "If there is another disappointing GDP number, then companies like Ingersoll-Rand are going to have some problems."

Responding to his next caller, Sirius Satellite Radio (SIRI Quote) is "trading up today," as is XM Satellite Radio (XMSR Quote), Greenberg said.

However, Cramer keeps saying that Sirius and XM Radio need to merge for their stocks to go up, he said.

"If and when they do merge, then you'll have a real company," Greenberg said. "They're losing money in the meantime, and you could be getting good dividends in other places."

"It seems like dead money here."

There is a high short position in MasterCard (MA Quote), Greenberg told a listener.

"You might want to ring the register on this one," he said. "I wouldn't recommend it here," because it's getting a little too pricey, he said.
