Earlier quoted context omitted.
My grandfather had $3M invested in the market in 2007. Lost $1M at the bottom in 2008, but didn't do anything other than rebalance. Now worth $8M. Either you fret over every price move and likely buy/sell at the worst times, or you invest with a long-term vision and stop tracking the price moves everyday.
yes but in that case the Fed rode to the rescue and delivered the greatest bull market in US history. There's absolutely no way the next decade looks like the last so this is a poor comparison. As far as rebalancing --- you may have noticed stocks and bonds falling in unison this year, so rebalancing is not much help.

And not sure what your comment on rebalancing not being much "help" is. Rebalancing is not about "help" it's about sticking to an investing approach.
And I can recall back in the early 2000's when people said "Equity growth will never be like it was the 90's".
Glad I never listened to them.
