Yes, markets fall. Sometimes hard. But no, a diversified 401(k) generally does not go from $800,000 to zero because CNBC found dramatic music for a red day. If that were normal, retirees would be checking futures before buying eggs. Can a crash sting? Of course. Can it crush someone who is 100% in stocks, overloaded in one company, or entering retirement with no withdrawal strategy? Absolutely. But headlines screaming that your entire 401(k) can be wiped out are usually designed to frighten people into the worst move possible. The market drops 30%. People panic. They sell. Then the recovery shows up without them. That is the real retirement nightmare. Not your account magically becoming $0 after one ugly quarter. If your retirement plan only works when markets never fall, the flaw was there before the crash.
