Just to add to this. I sold my AMZN, MSFT and AAPL and put it all into NIO at 39.5 last week. I'm not sure about your situation, but this is my play money account so I'm okay with the risk. My goal is to build it up to 100k and if I make it there, I'll probably reallocate to safe and boring blue chips.
IMO the trillion dollar companies won't give you the bang for your buck that growth stocks do. Even Tesla hasn't moved much since it split. Not to say that they can't pop later on, but right now is the time to get into NIO, PLTR, NNDM etc that have 10x potential.
