That goes for MBAs as much as MFAs, and it’s a lesson Lyft executives learned the hard way on Tuesday, when an errant zero sent its stock (briefly) to the stratosphere. The Lyft typo came in an earnings report that stated, incorrectly, that the company’s estimated gross margin would expand by 500 basis points, which would amount to a stunning five-percentage-point bump. The stock shot up more than 60% before Lyft’s CFO corrected the error on a call with analysts, bringing the stock back to Earth. With the error in the rear view, Lyft shares were up up 30% Wednesday, bolstered by stronger-than-expected earnings and a rosy outlook for future cash flows. “Look, it was a bad error, and that’s on me,” Lyft CEO David Risher told CNBC on Wednesday.
