its just trading/the way stocks work
if you have a stock that is trending down, eventually it will have a day where it will go up. Traders see that, flip their position, thus exacerbating the change
*easiest way to see if there actually was news is to check the moviestock page and see what the latest article is - as you can see on holm3, there is nothing under the "recent posts" section, so no news
