Remembering market wizard William J. O'Neil

Bill O'Neil died on Sunday, May 28, 2023 at the age of 90. RIP Billy'O (nickname given to him by NYSE specialists), humble man wearing a blue shirt and Mickey Mouse watch. He was an extraordinary investor. Here's what Gil Morales (his former portfolio manager) said about him: 

Well, the bottom line is that I would be nowhere in this business if not for the guy who taught me pretty much everything I know about trading stocks, Bill O’Neil. Bill is in my view the true “greatest investor who ever lived,” given that his CAGR over a very long period of time extending back into the late 1950’s is over 40%, and he has dealt with some very large asset sizes. O’Neil is a very humble man and a truly outstanding teacher, and the opportunity to work side-by-side with him for 8 years was a rare privilege for which I will always be grateful.
