Stock price isn't just based on a company's profits, there's so many factors into stock price that profit really is a minor one because profit doesn't take into consideration the value of assets like patents that have been developed by a company's R&D department, but the stock market does. Stocks prices also take into consideration expected future results, but profit doesn't. The market is largely expectation driven, some times those expectations turn out to be correct and other times it doesn't. Just look at how Ford consistently makes a profit and Telsa has been consistently losing money but Telsa's market cap is close to 50 billion and Ford's is around 44 billion. Airbus can't sell their planes to Iran because it contains American technology and they'd be in violation like ZTE was when they sold to Iran with Qualcomm's chip in them.
