Started my investing in 1995 when DOW was around 5500.
I sat through recessions, depressions, 911, too many wars (and viruses) to count.
The only times I took a big hit (by missing out on huge subsequent gains) is when I bailed. One was prior to the Y2K scare. I forget when the other was.
I’m about 20 % cash, widely diversified otherwise.
I’m down about 150k (on paper) right now, and I ain’t doing nuffin!
