Wow! Even with the crash, wouldn't you have been better off getting the last five years of gains, especially given interest rates didn't match inflation?
I was curious, so checked - $500,000 in VOO 5 years ago would have been 1.18 million today - already accounting for the crash so far. The market would need to crash an additional 60% starting with the next open to get you back to your $500,000 break even. Maybe this will happen, but that's quite a fall.
You make a personal evaluation that differs from the market and you act on it. You need a model of the world and to believe it is more accurate than the average. A lot of people felt the market was overvalued and would correct during the Trump presidency.
