In your 401k portal/website there's usually a setting like "I plan to retire on year X". When you set that, or something similar, there's typically a managed fund that gradually decreases risk as you approach that year. When you have lots of time before retirement you can ride the ups and downs but as you get closer the less time you have to recover from a downturn so the more conservative you want your investments.

If you're really worried and want to be conservative tell the portal you want to retire in 2030. That will allocate your investments to something conservative and you'll be more protected from a downturn. On the other hand, you'll also be equally protected from an upswing.
