Welcome! My goal is to do my very best to understand your situation and to provide a full and complete answer for you.
Good morning. If you think a crash is coming, I would definitely take the money out of the stock market and put it into a money market account. I will tell you it it difficult to time the market, and you do have time for it to recover again should it go down before you'll need it....just like the last time. The real key is how much you think you need for your retirement
...something called "critical mass." Once you reach your critical mass, then you don't want to take further risk because you have the money you need and the reward for doubling that amount is not worth the risk of having the market crash and cutting it in half; but, if you are well-short and you have a good while until your retirement, you will need a higher rate
than a money market will provide, so you will need it in the market over time. But, again, if you are sure it's going to crash, then I would take it out for a bit and wait for the correction at which time you can then re-invest it.
