Shares of SK hynix Inc., the world's second-largest manufacturer of computer memory chips, are zooming higher, trading near a yearly high as investors bet the chipmaker would rake in decent earnings this year on the back of a recovery in chip prices and its expanded market presence, analysts said Friday. Shares of SK hynix soared to a 52-week high of 39,250 won (US$36.9) on Wednesday on a continued buying spree by foreign investors, although it fell slightly to close at 38,850 won on profit-taking the following day.
