Universal Display (PANL -7.1%) slumps after top customer Samsung (SSNLF.PK) announces it sold ~63M smartphones in Q4. With Strategy Analytics having estimated 56.9M smartphone sales for Q3, investors may have been hoping for a bigger number for the year's strongest quarter. The decline comes as Samsung, LG, Sony, and Panasonic show off (costly) OLED TVs at CES - a 55" LG model will be available for a mere $12K in March. Skyworks (SWKS -2.2%), another Samsung supplier, is also lower. Samsung fell 1.3% in Seoul.
