If you like WallyWorld then by all means sell some AMZN.
It's good to diversify, however, you can't mess with the Beast, especially with AWS and the potential growth, revenue and earnings down the road.
There are a lot of rumors about spinning off AWS at some point. They could do something similar to what EMC did with VMWare years ago in which they spun off 20% and kept 80%, then EMC was bought by Dell Computer. Dell is now looking at a possible spinoff of the 80% to Dell Shareholders some time after September 2021.
Who knows, anything is possible.
Go AMZN!!!
