RealMoney Radio: Brakes on Boeing

"The airline cycle is alive and well," Jim Cramer told a caller who asked about Boeing (BA Quote) on his "RealMoney" radio show Friday.

Cramer predicted Boeing, which has dropped from $86 to $72, will make a stand at $70. That's the level to buy it at, but not before then, Cramer said.

He told the next caller he considers Aetna (AET Quote) worst of breed, as the company keeps missing its estimates.

On the other hand, UnitedHealth Group (UNH Quote), which Cramer owns for his charitable trust, Action Alerts PLUS, and is selling at one times its growth rate, "is the way to play this group," he said.

Although UnitedHealth's CEO is in the middle of a backdating scandal, Cramer believes the CEO "will be vindicated."

"I would sell Aetna very hard here because it's going from $36 to $30," he predicted.

Responding to his next caller, Cramer said he "likes Ecolab (ECL Quote) very much," as the company provides services, such as pesticide control, that people pay for regardless of the economic situation.

He advised anther caller to stay away from Gemstar (GMST Quote), calling it "a serial disappointer."

When a listener called in from Taiwan inquiring about Chesapeake Energy (CHK Quote), Cramer said "no one cares that [natural gas stocks] are cheap," even though he, himself, owns some natural gas for his charitable trust.

"I have trimmed back my oil holdings but I don't want to give up everything, because the world is a dangerous place and oil a good hedge against that danger," he said.

However, Cramer said he doesn't want to own Chesapeake right now, as he doesn't see a bottom in the group. He said "oil is in free fall" and compared it to "falling knives." Instead, Cramer said he prefers food and beverage stocks, financials and tech stocks more.
