A sharp fall in Wintek's June sales could signal that the company has lost out on orders for next-generation Apple products, specifically a new iPhone, says Topeka Capital Markets' Brian White. The analyst notes that on average, Wintek's June sales have grown 1 percent month-over-month. This year, though, they plummeted 33.6 percent, making for the company's worst month-to-month crash since late 2008.
