When you're in your 60's and you lose that much of your nest egg there's more than a little to be anxious about
Indeed. Those that say stuff like that are either young with decades more work time to make up the loses, or they don't have much money in the market to worry about.
Those that are in or on the edge of retirement depending on their investments best pay attention.
Then they'll say, the market always comes back. That's true. it will. I guarantee you that 100 years from now the market will be higher than it is today.
Can a guaranteed that a year from now? 5 years from now? 10 years from now? Maybe, maybe not. The NASDAQ took ~14 YEARS to claw back to pre-Tech Crash. 14 years just to get back to even. All during that time you money is locked up unless you are willing to lock in a loss. So even after you get back to even, you lost 14 years of opportunity cost where you earned nothing. If you were young and DCA in during that time with more income, then it wasn't so bad. If you were retired at the time, you just have to stare at that hole in your retirement for a loooooong time.
IMHO, there is a non-zero chance that the broad market will not get back to it's high last Nov for maybe 8-10 years.
