On the surface, Walt Disney (DIS -0.20%) stock stands out as an incredible buy, on sale for 33% off its 52-week high. But buying a stock just because its price is lower is usually a great way to get in trouble.

When building an investment case, it can be useful to play devil's advocate by poking holes through your own arguments. As Charlie Munger famously has said, "Invert, always invert. Turn a situation or problem upside down. Look at it backward."

So let's discuss the bear and bull cases on the media stock now to see if the discount on Disney stock is as appealing as it looks.

The bear case

The bear case against Disney is compelling and has real red flags that investors should consider. Through that bearish lens, you could argue that Disney+ faces an uphill battle -- and not just against other streaming players like Netflix (NFLX -6.22%), Amazon, Apple, and HBO Max, but also media in general, whether that's YouTube, video games, TikTok, or social media.

Disney's investments in Disney+ could be better spent on its parks or movie business -- which have high operating margins and a proven track record, and so they are arguably a better use of capital. And even those businesses could face challenges in the short-term in the form of pricing pressure in an inflationary environment.

What's more, Disney stock doesn't pay a dividend. And management has shown little to no interest in reinstating the dividend anytime soon.  Despite a blowout quarter, the company is generating a fraction of the profit it used to due to high spending and a business that is still rebounding from the pandemic.

The parks may be opening again. But Disney+ still must achieve long-term profitability for it to be a success. In addition to this underlying uncertainty, it's unclear how much of the surge in park performance is due to pent-up demand for vacations. As the COVID-19 situation improves, Disney needs to show that it can keep growing its park performance by, for instance, attracting repeat business from avid park goers. Deprived vacationers may be willing to accept Disney's price hikes and the added cost of Genie+ and Lightning Lane. But it remains to be seen if these added costs will be sticky over the long term.

The bull case

The problem with most of the bearish points is that they are short-term problems. Disney is a powerful global brand and a media machine that isn't going away anytime soon.

Disney's parks have exhibited impeccable pricing power even during times of inflation. For example, Disney noted that per capita spending at domestic parks increased by 40% in Q1 of fiscal 2022 compared to Q1 of fiscal 2019 -- a sign that customers are shrugging off Disney's price hikes. 

What's more, Disney+ has a far richer legacy content portfolio than newer pure-play streaming services. The value of hit Disney movies doesn't end at the box office, but rather has a longer shelf life because they can be added to Disney+, generate revenue from merchandise, and even provide the inspiration for theme park rides and attractions. Unlike other streaming providers that desperately have to spend more money on content to keep subscribers entertained to justify price hikes, Disney has a much more efficient and lasting business model.

Disney+ is worth investing in because it could provide the first touchpoints for lifelong Disney customers. The lifecycle of a Disney customer tends to begin during childhood from someone that grew up with Disney, maybe went to the parks or played with the toys, watches the movies, and then passes along that joy to their kids. Disney+ hosts decades of high-quality content, and is home to new content that adds value to the worlds that Disney characters live in. Therefore, Disney+ seamlessly integrates into Disney's overall content portfolio and could very well boost engagement at its parks and movies over time as consumers become more involved in various Disney universes like Star Wars and Marvel.

Where to go from here

Stock prices ping pong up and down because investors have different ideas of what a company is worth. Yet most of the short-term price movement can be far removed from the long-term investment thesis.

When I look at Disney's business today and its trajectory vs. Disney's business three or five years ago, I see a company that is only getting better. I see a company with a much more sustainable and diversified business model than, say, Netflix. I see a business that is developing characters, making memories, and providing so many different entertainment outlets on and off-screen. These green flags far outweigh short-term red flags regarding Disney's lower profits and lack of a dividend.

But I also understand that some investors may prefer waiting awhile to make sure Disney+ amounts to everything Disney hopes it will become before hitting the buy button.
