As oil soared early, markets were hit hard. Both reversed course as the day progressed. Amazon had its own news today, too. Its Zoox robotaxi service will be rolling out in Phoenix and Dallas for testing. Amazon will test the self-driving technology using retrofitted SUVs before formally offering commercial service. Late last year, Zoox began operations in Las Vegas and parts of San Francisco. Investors are also considering what UPS’s strategy moving away from lower margin Amazon business might mean for Amazon’s delivery services. Today’s oil price action highlighted those potential concerns with the company’s future margins.
