Short Netflix stock: Dan Nathan

Despite the seemingly good news surrounding the stock, Netflix is a short, Risk Reversal's Dan Nathan said Tuesday.

"It's about as good as good as it gets right here," he said. "I think there is going to be another wave of selling."

On CNBC's "Fast Money," Nathan added that he believed investors are going to drop high-valuation names like Netflix and look to add more defensive names.
