Tesla shares slide after Amazon invests in self-driving company, Aurora

Tesla revealed that it has lowered the price of its Model 3 again. Tesla shares slid Thursday afternoon after self-driving car startup Aurora said it raised more than $530 million in funding from investors including Amazon, Sequoia and the investment arm of energy giant Shell. Tesla shares were down more than 3 percent, near $305.60 a share after the announcement was published. Markets Insider reports that Thursday's selling has Tesla shares teetering toward their lowest close since Jan. 29, the day before the electric-car maker's fourth-quarter earnings report. Amazon made "significant investments" in Aurora, the tech start-up said in a press release.
