The Japanese yen is at approximately the weakest point of the year (there was a single day in March where it was briefly this weak.) That's great for the health of Nam Tai's customers Japan Display and Sharp. Even a few percent change in exchange rate makes a significant difference in their profitability. Meanwhile, the Korean won is at approximately the strongest it's been all year (there were 3 stronger days this year, all in November or December). That hurts Samsung Display and LG Display, the Korean competitors of Japan Display and Sharp. Finally, the Chinese yuan has held steady which means the cost of Nam Tai's workers isn't going up quite as quickly as it was in past years.
