Boeing's (BA) mixed earnings showed enough green lights for investors to send shares higher on Tuesday's session. Morningstar Wealth's Nicolas Owens says one of the key questions lies in a key customer and a tentative setback of orders. However, he still sees the stock as one flying under fair value. Ben Tsocanos believes the aerospace giant's turnaround story continues to gain altitude on what he calls a "pretty solid quarter." He points to Boeing's backlog offering muscle to future earnings.
