It always happens. Take any 40 year block of time with mutual funds and it works out every time as long as the funds aren’t mostly bond funds. And, after 20 years, there is no volatility in the market. I do this for a living and have all the stats to prove it.
What does happen on occasions is when people get near retirement, the market goes down and they have to work longer. One can move the money into safer assets close to retirement. Even guaranteed income vehicles. What you should have done before asking for the money is moved it into a money market inside the 403b and then taken it out. Brandon hasn’t a clue how the economy works.
I have a client who retired last year. Rolled it over to an IRA. Right afterwards, it dropped from $425,000 to $390,000 because of Brandon. But, because of capitalism, it soon rose to $470,000. Then it dropped again recently to $440,000. But is back to $461,000. During that time, has taken out $25,000 for retirement. A little each month. It’s all in asset allocations of stock funds. None in bonds. And the dividends and capital gains have been huge.
In the SS system, people would be required to shift from stock to bond funds.
