<prompt> Human: I am 40 years old and have a sizable 401k thats pretty heavy in stocks 40 percent sp Should I consider moving to bonds or something more stable before the stock market crashes?My thought was to move everything over, and once things crash, move back to stocks to buy cheaply.Does this make sense, or should I just ride it out?  <response>: What evidence do you have that the stock market is about to crash? How would you know when the crash is over and its okay to buy back in?
