Stock prices fell after reports that Chinese government workers have been banned from using iPhones.The drop in stock prices comes at the same time as the release of an important rival phone in China, the Huawei Mate 60. Apple’s iPhone 15 event on Tuesday will boost stock prices for shareholders but it will not be enough to recover its stock market valuation which fell by more than 6%, or almost $200bn (£160bn), in two days last week. Will iPhone be able to recover anytime soon ?
