Hello, I recently saw a video about a person who compared investing every month into the #1 stock vs investing into the S&P500. The #1 stock method outperformed the S&P500 by a large margin and I’m wondering if it is actually a viable option. Of course you are putting all your eggs into one basket and it is a big risk with your investment but does it actually outperform it and why? Is it best to keep old stock or sell and invest 100% into the new stock? Thanks
