The idea of a Coffee Can is simple: You try to find the best stocks you can and let them sit for years. You incur no costs with such a portfolio, and it is simple to manage.
I share mine here: https://docs.google.com/spreadsheets/d/1tBrZEMFK9XNWxiqOxE8o...
Are you just referring to the default white cell background that google sheets have?
after looking into it further, it shows up as black text on desktop but white text on mobile for some reason ?...
Btw, I noticed you used to work at Opera. As you might have seen on the sheet, I recently invested in them. I'd welcome the opportunity to hear your perspectives on the company. Would you be open to a brief chat about the company?
Take care.
