Amazon & Rivian Deliver Upbeat Earnings, Coinbase Falls

On this episode of Stock Movers, we look at some of the week's biggest gainers and decliners:

- Amazon (AMZN) shares rallied in extended trading after it delivered earnings that beat Wall Street estimates. The e-commerce and cloud-computing company reported second-quarter results that beat expectations on key metrics, including revenue at its Amazon Web Services business. However, it also gave a third-quarter revenue outlook that was weaker than expected.

- Rivian (RIVN) reported better-than-expected earnings as it began deliveries of a new midsize sport-utility vehicle, a positive sign while the company contends with a weakened market for electric vehicles in the US.

- Coinbase (COIN) reported total revenue for the second quarter that missed the average analyst estimate. Shares traded lower in extended trading.
