No deep analysis on this one. I just think it's a crazy good deal to be able to buy stock of the biggest corporations which lead humanity technological progress, have huge political influence and even at today profit levels return 3-4% per year (in reality much more as a lot of money is invested in research/new projects which are going to be profitable in the future). I think Apple/Amazon/Alphabet/MSFT etc are going make even more in the future and current price is a steal, especially considering those are highly liquid assets with 0 cost of maintenance.
