Investors Should Be Patient Before Buying the Dip in Universal Display Corporation Stock

Universal Display Corporation (NASDAQ:OLED) opened much lower despite beating earnings and revenue expectations. Universal Display stock has flown high and then fallen quickly as iPhone-driven sales failed to match expectations. Universal Display, famous for its organic light-emitting diode (OLED) technology, reported a Q4 2017 profit of 93 cents per share, eight cents per share ahead of estimates.
