How does the growth of TSLA compare to AMZN? For years, AMZN did not make profits as it built out and expanded. Were there people trying to short AMZN and predict it's doom? Nothing is new in the world, so are there other similar things in history to compare these decision indicators?

Tesla's rise this year is obviously extreme, but it also traded sideways from 2013-2018. Over a decade AMZN is up 25x, TSLA 150x

From my perspective, these multiples aren't valuable. Metrics like Price:Sales ratio are,

AMZN's P/S is 4.75, it has climbed sharply, but it has usually hovered between 2 to 3.

TSLA's P/S is 25.09. The P/S ration has increased exponentially from a historic low (for the company) of 1.74 to the 25+ territory, https://www.macrotrends.net/stocks/charts/TSLA/tesla/price-s...

You can't really compare the P/S ratios between different industries. A lower margin business like retailing should have a lower P/S ratio than a higher margin business like retailing. OTOH, a crazy high margin business like AWS should have a higher P/S than a manufacturer...
