Uber is imploding. Is it time to invest in Lyft instead?The past year has been non-stop bad news for Uber, the $70 billion tech "unicorn" company of the ride-sharing market. From allegations of sexual harassment within the company to an exodus of C-level talent from the company to legal battles with Alphabet subsidiary Waymo, labor disputes, and a complete and utter lack of profits, Uber has done an exceptional job of totaling itself and opening up a lane for Lyft to drive right by.Investors may now be tempted to leave Uber stock by the curb, and buy into its archrival Lyft instead.
