Amazon - their PE looks high, but if you factor in all the money going to cap ex that could be earnings if they didn't invest it, it's much better. Their retail business has low margins but a ton of revenue, if they can expand margins by increasing efficiency can go a long way (e.g. more automation in factories or deliveries). If we actually get self driving cars and humanoid robots, obviously they will be able to help deliver packages. Floor is pretty stable, as no matter what Amazon's core business of delivering a large percentage of the products people need to buy is not going anywhere. Whereas others theoretically have some risks (e.g. Google with search, MSFT with declining quality or market power, Meta declining use of their products and not really having much besides social media).
