'Halftime' trader Jon Najarian sells everything

"Halftime Report" trader Jon Najarian liquidated all of his holdings in his CNBC PRO model portfolio on Friday morning, uneasy about how the market is trading due to the lack of direction from the Federal Reserve as to what's next for interest rates.

"I don't think the market is ready for it," said Najarian, explaining that if the central bank were to move, stocks could plunge between 5 and 8 percent.
