Pete Najarian with Market Rebellion isn't surprised to see a pullback in Carnival (CCL) after the cruise line's earnings despite posting a beat and strong guidance. He points out the company's massive year-over-year rally that waved the yellow flag for a cooldown. That said, Pete points to the company's low P/E ratio showing value for long-term investors. Tom White offers example options trades for Carnival (CCL) and Royal Caribbean (RCL).
