Apple shares got a boost Monday after the company announced that preorders for the iPhone 6S and iPhone 6S Plus were on track to beat the previous 10 million unit first-weekend record set in 2014.
"Customer response to iPhone 6S and iPhone 6S Plus has been extremely positive and preorders this weekend were very strong around the world," the company said in a statement, adding that demand for the iPhone 6S Plus in particular has been "exceptionally strong." The stock was up 1 percent midafternoon Monday.
But while many view the pop as a sign that things could be turning around for Apple, one trader is betting on another selloff.
"I have some concerns with the chart, and I think Apple is going to head lower," Andrew Keene said Monday on CNBC's "Trading Nation." Shares of the tech darling are down 14 percent from the recent high hit in late April.
