That is if you are investing for the long run (retirement). It can give you stress and worry your mind even when it shouldn't.

You value going to fluctuate, sometimes dramatically. There will be times where you are down quite a bit. But if you are not a day trader, you are not going to be pulling your money in and out of the market trying to perfectly time the market.

I think it's best to just forget about it and maybe check on it every few weeks or so.
