3pm was a raid on all of the people in this industry sector that had a price point trigger set to automatically sell if the price dropped below a certain point. People were spreading fear all day that the bottom was going to drop out from under these stocks and then they created the drop to buy more shares at a 50% discount. The hardest hit dropped 50% and then still bounced back up to a new record high... It was based on nothing but grabbing millions more shares to unload tomorrow at the same, if not higher than today.
