Subject: Re: BRKB vs SPY last 5 years
there was a poster on the MF board named div20 or something like that who would constantly pound the table of BRK being inferior to the S&P.

There were two stocks they asserted would be 10 baggers. Quantumscape (QS) and Confluent (CFLT). I bought some of each in the paper trading account I used for strategy testing. After holding them for years, both were down over 50% from my purchase price when I finally got rid of them a few weeks ago.
