I didn't think their stock would tank. The bad news was already priced into the stock. The stock shouldn't have tanked and it shouldn't have surged liked it did. And the funny thing is you admit it shouldn't have surged like it did at the end of your post.It makes perfect sense. See my post above.
If you really want to know why it makes sense you'd have to get into the finer details of stock trading. Maybe it's a short squeeze crucifying people that thought for sure Disney stock was going to tank after the earnings call so they went short? Maybe large companies are buying it because their 6 figure paid analysts and researchers who have spent decades studying the theme park industry (yes many financial companies have industry specific experts) and the stock market itself think it's a good buy right now?
It's moving upward due to a multitude of factors. Soon it will likely drop because it's moving up too quickly. That is how the markets work.
