Boeing Stocks Plummet Following Analyst Downgrade To Underweight Over Cash Flow And Delivery Issues

American aircraft manufacturer Boeing has seen its stock values tumble around 8% after multinational financial services company Wells Fargo reported a downgrade to the company. The reasoning behind this is due to unsatisfactory performance following cash flow limitations. Aircraft delivery delays have directly affected bottom-line costs to the manufacturer, and the banks lending money to Boeing have said it has seen growing production cash flow running into a new aircraft investment cycle, capping free cash flow a few years out.
