We did a 403b retirement fund/mutual funds (American Funds) via deferred income for the last 18 yrs or our employment. I don't micro-manage our investments and last year our investments increased by 19%. Over the last 29 years our total investments have more than quadrupled. We are very pleased. I was gobsmacked actually. I really wasn't expecting that kind of increase for 2020. About the only good thing to happen in 2020.
