<prompt> Human: My 401k returns year to date are currently 18. Yeah, I set it up well thanks to this sub... but not THAT well. The stock market has had a record year but value to earnings ratios are the highest theyve been since... forever I think. This things gonna crash, right? It has to, doesnt it? Lets assume that this is the case. I want to protect that 18. The smart thing to do would be convert holdings into bonds, wait for the crash, then re-invest in stocks at the trough assuming that Im a fortune teller.Is that correct? What else are good ways to hedge against what is looking like an inevitable crash? EDIT: Yes, I know that I am making predictions. Yes, I know that they may be wrong. Lets assume they are correct. How would one best protect gains?  <response>: No. Dont try to time the market.
