Kaminsky noted that

Barclays PLC

(BCS) - Get Report

was surging 12% today because it was benefiting from a good quarter, especially from the former Lehman business unit it owns.

Kaminsky said he expects the European banks, including those in Germany, France and England, to have a difficult time because of sovereign debt problems in Greece and other countries.

Jon Najarian said he was taking the cue from Kaminsky and lightening up on European banks over the next 30 days.

Shifting to the airline sector, David Barger, CEO of

JetBlue

(JBLU) - Get Report

said his airline did well in canceling flights ahead of time before the big snow storm on the eastern seaboard. He said very few passengers have asked for refunds.

Barger was coy about upgrading its relations with Lufthansa to a partnership, noting its current network relationship with the German carrier is a good working relationship for both carriers.

On the housing front, Ara Hovnanian, CEO of

Hovnanian Enterprises

(HOV) - Get Report

is doing well despite receiving negative comments from analysts.

He said the company holds long maturities to its debt, has a $300 million tax rebund check coming and $500 million in cash. With half the competitors gone in the industry, the company is well positioned for a turn in the market, he said.
