Decide for your investment. If you can afford seeing how this market is falling, then choose to hold. But if you are into short term holding, you are free to sell because no one knows how low will the market price be or if there will still be a chance for this market to recover. In my case, I'd hold my remaining investments because I am not needing money from my investments at this moment, and it would be fine even if the price would be lower, and I will probably invest more in such case. That's simply how this market behaves and if you will panic, the result will just be permanent loss.
