To understand the background to my question. It is "free money" if you match, so your still reducing you're "take home pay" and depositing it into an account that's constantly losing.
I'm still not understanding - how does your employer match work? They only match a very small % of what you put in? (I understand usually employers match some percent up to X% of pay which is essentially free money - so for example on 100K income they'll match (say 50% on 5% of income) then the first 5K you put in - out the gate you're getting $2,500 free money.)
Regarding staying the course or not I would echo what earlier posters said with the caveat on where are you in life? I.E. if you have another long term (10 years or more? very hard to know what long term actually is) to wait for it to recoup and grow more than I view it (Like I think
@aygart said) as funds being on sale and try to pick up more than usual until market starts rising again. If you're planning on tapping into these funds soon (retirement? Simcha iyh? etc) then you probably should've been moving into "less volatile" investments like bonds etc for a while - although I think that's what target date funds usually do.
Ultimately what I guess I'm saying is (depending on what you actually mean by minor employer match) deduct up to the match to get the "free money" and if you think you shouldn't be in that Target fund then move it into a fund you're more comfortable with.
