Samsung’s shares fell more than 5 percent on Thursday to its lowest in over four months, because the cocaine nose jobs of Wall Street fear lower quarterly earnings due to the strong won currency and weaker margins at its display business. The company has lost nearly $18 billion off its market value lately.

Samsung, the world's largest maker of smartphones, memory chips and televisions, is scheduled to report its October-December quarter earnings estimate next Tuesday. The company is expected report a one percent increase in operating profit from the previous quarter although some nay-sayers think there might even be a 3.6 percent quarter-on-quarter drop in Samsung's operating profit.

The biggest reason would be the won-dollar exchange rate, followed by shrinking margins in organic light-emitting diode (OLED) sales.
