You cannot predict the market. Here is a Forbes article citing the same issue in December and speculating that the stock market would not rise in 2019. https://www.forbes.com/sites/jessecolombo/2018/12/31/when-th...

If you had pulled out of the market at the end of 2018 expecting a bigger drop, guess what, you would have missed one of the fastest market comebacks.

The scenario being discussed is just one possible outcome. There are numerous other outcomes as well. You can off course bet on this scenario and pull your money out of the market, and if the crash occurs, you can tell everyone about how to timed the market. Or you might be the person who lost big time.

As with all speculation...only time will tell
