Robert Downey Jr. rings the opening bell at the New York Stock Exchange as Iron Man 3 debuts in New York City.

Heading into its fiscal second quarter earnings announcement on Tuesday, Disney shares are trading around an all-time high, up about 50 percent over the past 12 months. With analysts growing increasingly optimistic this quarter, and the majority of analysts rating the company a "buy," the big question is whether the media giant will beat expectations as it did last quarter, sending the stock even higher.

Disney's biggest and most profitable division—media networks—will be in the spotlight. New carriage deals for ESPN, are expected to push revenues higher. Still, investors will have a keen interest in how advertising is faring at the networks. Disney's also been investing in its parks division, so investors will be looking for margins to start growing.
