Are we done with picking mediocre stocks yet? Like Bank of America, in particular.
The next Berkshire CIO will do spectacularly better by just buying the top 1000 market cap stocks in equal amounts and holding them. Maybe put 90% of investment portfolio in those, and pretend you can pick stocks with the other 10%, still tens of billions of dollars so some real money.

Whatever past calculations they did, they missed the non-tech stock I bought, which compounded at 24.4% over the last 14.5 years. I am sure a lot of the upside is due to luck, but some of it, without bragging, due to skill. ie foreseeing that it was dirt cheap and safe(ish).

I won't even mention the tech stocks which have been, are, and will be multi baggers that Berkshire, out of fear and ignorance, will continue missing out on. Oh well. I can live with that.
