There's no comparison between Amazon and Uber. For a start, Amazon's business model is based on low margins and high revenues - its profits are never massive (at least not for a company of its size).
Secondly, Amazon's share price didn't dip below its IPO price. Uber's price has scarcely risen...
Uber is no long-term disrupter; it lost $5 billion last quarter, its share price is heading ever south and has never turned a profit. It won't last another five years.
