Short answer - probably not. By retirement age, your investment portfolio should be more conservative, less speculative. Yes, the market is down. NO, it's not that serious a slide. Here is a picture of my Duke investments for the last year. It went up most of the year. It's down, but no more than it was at the beginning of the Trump administration. In that time, jobs have also grown, manufacturers have brought money home to the USA, and we've gotten an decrease in the tax rate. I would NOT expect a implosion in the investment market.
