There’s so much uncertainty around Boeing’s future that its stock has fallen 30% year-to-date, making it the right time to start buying up shares, UBS analysts say in a research note. That short-term shakiness can be chalked up to potential regulatory actions in response to the company’s recent woes, impacts on production of its MAX models and questions around the certification of those planes, making the stock tough to own for existing investors, the analysts say. But on a multi-year horizon, the stock still makes sense as new aircraft demand remains at record levels and supply challenges are poised to keep the market undersupplied for years to come, the analysts say.
