Based on the user name I'm going to guess that they are getting the data from books.
A smart strategy when you are predicting a decline in prices is to price today based on what you think prices are going to be in six months. Because in six months when everyone is feeling the pinch, that is going to cause prices to be lower than what we are predicting them to be in six months. Simply put, this is a glimpse into our future and a sign of where things are moving.
I think you are saying things that might not be entirely accurate. Sure, Disney is getting hurt by the park closures which could theoretically extend through the summer and into the fall. However, they are a more diversified company than they ever have been. Additionally, they have about six billion dollars of cash on hand and just raised another seven billion dollars in debt. This is not something you do if you think you're going to be closed for two months. They have positioned themselves for multiple scenarios far worse than what we are seeing now. I think that the worst-case scenario for Disney is that they are not profitable for a few years as they dig their way out of this. There are worse things. And while possible, I think that acquisition, bailout, or bankruptcy are outside the range of likely outcomes.
