Right now it is very obviously testing support. It is a speculatively overpriced company based on expected future growth, at a time when it looks like the overall market is likely to crash. This is obviously a very precarious time and it could very likely fall below support, which looks like it would likely drop to around $10.

Yes, if you have full confidence that it is going to succeed abroad and you don't want to spend time watching it, then forget about it. If you keep a close watch on it, even if you believe in it for the long haul, it does make sense to think about the possibility of shorting your own stock and increasing your holding by selling out now and buying back in at a lower price. It's difficult to be certain of what will happen, but it seems likely. Some people probably think it's likely enough to give it a go.

Also don't forget that we've just seen disappointing results from the foreign side of things, which the market has already priced in as a success. Any measure of the company being in the negative when 'exponential growth' is already priced in leaves something like this in an extremely precarious state.

You can irrelevantly mock people who try to buy at absolute bottom and sell at the absolute top, but currently it is falling, so by your own logic, selling right now likely makes sense to people who aren't absolutely committed to holding long term.
