The Magnificent Seven—not the movie, one of the greatest westerns of all time starring Yul Brynner and Steve McQueen, but Apple (+35.2%), Amazon (+50.0%), Microsoft (+34.1%), Nvidia (+205.9%), Alphabet (+53.3%), Tesla (+111.1%), and Meta Platforms (+153.3%). Through October 5, 2023, these stocks had returned an average of almost 92%.

What, if any, implications does such a dramatic dispersion in returns have for investors?
