Typo in Lyft earnings sends shares aloft nearly 70%

What a difference a zero can make. 

Lyft shares went on a short-lived ride after Tuesday's closing bell, surging as much as 67% after the company issued an outlook mistakenly projecting that its margins would expand an astounding 500 basis points.

Less than an hour later, the ride-sharing provider offered that the estimate had missed the mark — by a lot, with the real estimate at 50 basis points, or a half of a percentage point.
