I lump sum invested my life savings at the ATH. I’ll lump sum invest my 2nd pillar in the coming days, despite the SP500 being at 3000+ with 40 million unemployed, starting civil war, the pandemic and international tensions. Why? Because the odds are never better for DCA.
If I wouldn’t do it, then being 100% into stocks would basically be the wrong AA for me. There is no return without risk.
