Trump's "Delivery Boy" tweet helps wipe ~$53B off Amazon
March 29, 2018: Trump tweeted that Amazon pays "little or no taxes" and uses the Postal Service as its "Delivery Boy." Amazon (AMZN) fell roughly 6% by the close — its worst stretch in about six weeks — erasing on the order of $53 billion in market value. The post followed an Axios report that Trump was looking for ways to curb Amazon; Jeff Bezos also owns The Washington Post, a frequent target.
