If You Had Bought $10,000 of Apple Stock When Tim Cook Became CEO, Here's What You'd Have Today

Tim Cook stepped down as CEO of Apple (NASDAQ: AAPL) on Sept. 1, 2026, after an eventful and successful 15-year run. But does he get the appreciation that he's due?

First, Cook had the bad luck of following a particularly dynamic leader. Steve Jobs, who helped co-found Apple in the 1970s, led the company through the first boom of personal computing, helping introduce Apple's early computers and the Macintosh. And then, after he returned to Apple in the 1990s, Jobs revolutionized the music business by leading the company's launches of the iPod and iTunes, and then revolutionized the smartphone with innovations such as a touchscreen interface and an easy-to-use camera.

Cook, meanwhile, came in for his fair share of criticism in his 15-year tenure at Apple, as dramatic innovations have been far less frequent in recent iPhone models. The company has also been criticized for its artificial intelligence (AI) strategies, as its Siri digital assistant has been eclipsed by generative AI products such as Grok, ChatGPT, and Claude.

But Cook did some great work as well, and investors reaped the rewards. He continued to develop Apple's powerful services segment, which includes high-margin offerings such as the company's App Store. While big tech companies raced to build massive AI infrastructure, Cook instead focused on the user experience and on embedding AI into billions of devices.

Apple's market cap when Cook took over on Aug. 24, 2011, was about $350 billion. Today, it's more than $4.6 trillion. Apple stock has gained 2,280% since that fateful day, and had you had the foresight to invest $10,000 to mark the change in leadership, held on, and reinvested your dividends along the way, you'd have a position worth more than $284,000 today.

So yes, Cook had a great run. Here are three ways in which he made Apple a better company.

Apple's services segment has been a huge winner

Among the best things about Apple is its loyal customer base. That was one of the things that most attracted Warren Buffett to Apple while he was CEO of Berkshire Hathaway -- Buffett asserted in 2023 that an iPhone user would turn down a gift of $10,000 if it meant surrendering their iPhone and never buying another.

And that matters for Apple investors. The company's massive distribution system means there are now more than 2.5 billion active Apple devices around the globe. And that means more people accessing its digital content, such as Apple Music, as well as buying and downloading products from the App Store or using Apple Pay to send and receive money.

Apple's services segment generated $30.73 billion in revenue in the company's fiscal third quarter (which ended June 27), up 12% from the prior-year period. More importantly, the services segment had a gross profit of $23.24 billion, with a margin of more than 75%.

Hundreds of billions in stock buybacks

Under Cook's leadership, Apple became a cash-producing machine, with free cash flow rising steadily during his tenure to top $123.3 billion on a trailing-12-month basis in 2025. And Cook used that money, in part, to bolster the company's stock price. Its stock buybacks began in 2013 and grew as free cash flow increased. By 2025, Apple had reported $91.8 billion in stock buybacks over the previous 12 months. And the steadily shrinking number of shares outstanding pushed earnings per share higher, and helped the stock price appreciate considerably.

According to research by The Motley Fool, Apple has spent more than any other company on stock buybacks over the last 10 years. The company has repurchased $877 billion in shares under Cook's leadership.

Cook carved a different path in AI, but one that makes sense for Apple

Apple has made plenty of missteps when it comes to artificial intelligence. Siri was a great achievement when Apple introduced it on its iPhone in 2011 as the first smartphone digital assistant. But the company failed to capitalize on that early lead and now finds itself playing catch-up.

At this summer's Worldwide Developers Conference, Apple introduced a more advanced version of its assistant, Siri AI, that will be embedded for free into new Apple devices. Max Weinbach, an analyst at Creative Strategies, said that the rollout could be huge for Apple. "Siri AI is basically what most consumers use ChatGPT and Gemini for," he wrote in a social media post. "RIP consumer ambitions for AI companies."

Apple has said Siri AI will be a "profoundly more intelligent, knowledgeable, and capable Siri" that can answer questions about something on a user's screen and get real-time information from websites and apps. The company is also focused on embedding AI applications and intelligence into its operating systems and devices, rather than investing hundreds of billions of dollars in cloud infrastructure. Considering that Apple now has 2.5 billion active devices, the potential for Siri's AI is vast.

Cook didn't need to be Steve Jobs to be successful

Tim Cook has left Apple in a much stronger position, and long-term investors have profited mightily from his leadership. While he doesn't have the same charisma or flair as Steve Jobs, his tenure shouldn't be overlooked.
