Samsung reported a steep drop in Q3 profits with the release of its quarterly earnings report. Profits fell 44.4 percent compared with a year earlier — a number that, not surprisingly, sent the company’s share price tumbling by 14 percent. Although some product lines performed respectably — mobile handsets, for instance — the company could not overcome the industry dynamics affecting its core business: Falling prices for semiconductor chips, coupled with a global glut of product have sent profits and stock prices tumbling throughout the sector.
