TDK dropped by 4.46 percent while component supplier Murata Manufacturing declined by 3.09 percent.
Over in South Korea, LG Display fell by 2.63 percent while industry heavyweight Samsung Electronics bucked the overall trend by trading up by 0.22 percent after earlier announcing that its third-quarter operating profit was likely to have risen to a record high.
The moves in Asia followed a report released on Thursday by Bloomberg BusinessWeek, which alleged that data center equipment employed by Amazon Web Services and Apple could have been vulnerable to spying from the Chinese government as a result of a micro chip being inserted during the equipment manufacturing process.
The chips, which Bloomberg said have been the subject of a top secret U.S. government investigation starting in 2015, were used for gathering intellectual property and trade secrets from American companies and may have been introduced by a Chinese server company called Super Micro that assembled machines used in the centers. Amazon, Apple and Super Micro have disputed the report.
One analyst said, however, that the recent stock moves are unlikely to last long term.
“I think it’s a bit of a knee jerk reaction to the news,” said Leo Sun, a tech and consumer goods specialist at The Motley Fool, adding that the controversy surrounding Super Micro was “only about server chips, not iPhone components.”
Sun also highlighted that Apple’s current suppliers were unlikely to be immediately hurt as the company “ended its relationship with Super Micro back in 2016.”
Sun did, however, add that the report would likely serve as impetus for the American government to “cite this incident to pressure Apple to move its production back to the U.S. and use U.S. components.”
“I doubt Apple will ever comply, since its costs would jump significantly, but it could cause investors to avoid Apple’s Asian suppliers until the matter is resolved,” he said.
