Amateur here, so apologies for any incorrect understanding or terminology.
I've been purchasing fractional shares for several years now (\~$300/month for \~$28k total) with an evaluation of \~$57k (so approximately 100% gain). With things the way they are now and the drop in the market, would it be a good idea to sell COST right now before it goes lower? I know the market will most likely recover but, with no certainty on when, I'm thinking of selling now and then buying low. Any advice is welcome.
