Campbell, an analyst at Mirabaud Securities, believes that one of his biggest concerns is the oversupply of chips. Mirabaud Securities has tracked TSMC's inventory data for more than a decade.
Camplin said the current situation has caused investors to worry about the AMS, a key supplier of iPhone X 3D sensing technology. He said that TSMC's record inventory level is because Apple has not purchased components for the future iPhone X, suggesting that the phone may be discontinued this year.
He said: "With the decline in iPhone X orders and the record of TSMC's inventory, it basically reflects the need to sell inventory first. Why? Because iPhone X is finished. He said that the iPhone X problem is simply too expensive."
Mizuho also issued a report that various data show that demand for iPhone X is weak, and orders for iPhone 8 and iPhone 8 Plus are steadily declining.
Cham Siegel, an analyst at Elazar Consulting, said, "The demand for mobile devices will be weak before the new iPhone will start driving the supply chain this fall."
