I’d only add that if you’re just about to retire (in the next year or two or three), having some money on the sidelines makes sense, given SORR. I have half my money sitting on the sidelines, because I just retired, and if the market tanks tomorrow I’ll sleep better. But I do intend to invest a slightly higher percentage each year (and will buy to rebalance if we get a big drop). I might top out at about 65% in the market, 5-10 years from now, unless my assets grow (or spending diminishes) to where risking more feels more comfortable, and it becomes about funding the grandkids education, etc.
