2. -- Samsung Falls as Guidance Comes Up Short

Shares of Samsung Electronics Co.  (SSNLF)  fell to a near two-week low on Tuesday after the tech giant provided fourth-quarter earnings guidance that was modestly shy of market expectations amid a stronger South Korean won and slumping smartphone demand.

Samsung said it sees operating profit of around 15.1 trillion won ($14.1 billion) for the three months ended in December, up 64% from the same period last year but short of the Wall Street consensus of $14.9 billion. Overall revenue for the period likely hit 66 billion won, a figure that also missed analysts' forecasts.

Samsung fell 3.11% in Seoul to close at 2.52 million won, the lowest since Dec. 27, amid concerns over pricing power in the DRAM and NASD chip markets and slowing demand for smartphones in a hyper-competitive global market.
