Intel reported revenue from its PC-centric business, its largest unit, rose 16 per cent in the third quarter to US$10.2 billion. "After seven years of decline - and some belief that it was in perpetual decline - what we've seen this year is some stabilisation," interim chief executive officer Bob Swan said in an interview. The shares, which had closed at US$44.31 in regular New York trading Thursday, rose as much as 6.5 per cent in extended trading following the report, then pared the gains to less than 1 per cent after Mr Swan cited the possibility of a growing trade dispute between China and the US as a headwind for next year. He also reminded analysts on a conference call that the Asian country is a "big market" for Intel and an important part of the global supply chain. Mr Swan's caution followed an already tough week for the chip industry.
