Shares of Boeing (BA +1.57%) finished up more than 5% today after the company released strong earnings numbers. Motley Fool Supernova analyst Matthew Argersinger was pretty impressed by the numbers and is especially surprised that a Dow stalwart like Boeing has moved so much today. Then again, with numbers like 170 commercial airplanes delivered during the quarter -- 23 of which were 787 Dreamliners (double last year's number) -- and $415 billion in its backlog, Matt thinks the company looks strong.
