After WWDC news, debate returns over Berkshire’s Apple exit as AAPL climbs

Apple’s latest round of news tied to its annual developer conference, WWDC, has reignited a familiar question for equity watchers: did Berkshire Hathaway and its leadership make the right call by trimming Apple stock starting in mid-2023? The debate is being amplified in market commentary that points to a simple yardstick, Apple’s share performance since Berkshire began unloading its stake.

According to the commentary circulating through financial news outlets, Apple shares have gained about 50% since Berkshire Hathaway started unloading Apple stock in mid-2023. That kind of post-exit rally naturally raises the “what if” scenario investors weigh after a large, high-profile holding is reduced or exited.

The discussion centers less on a single Apple product launch and more on timing and opportunity cost. WWDC, Apple’s flagship event for software developers, is typically a key announcement for where the company is steering its platform roadmap, including operating-system changes and developer tooling. Whether those announcements translate into revenue growth for Apple is often a longer-dated question, and market reactions can be uneven as investors balance near-term hardware demand against software ecosystem momentum.

In the immediate wake of WWDC-related news, the commentary frames Berkshire’s mid-2023 selling as a move that now looks better in hindsight if the company’s technical or fundamental outlook had deteriorated. Instead, Apple’s stock performance over the subsequent period has been strong enough to give skeptics of the sale an opening to argue that the exit may have been premature.

Apple itself did not provide, in the materials referenced by the commentary, a direct explanation tying Berkshire’s trading history to Apple’s current execution. The company’s public communications around WWDC generally focus on what developers can build and what features are coming, rather than on investor-by-investor portfolio decisions. As a result, the current debate is more about what the market has delivered since mid-2023 than about any newly disclosed Berkshire rationale.

Separately, the question touches on a broader dynamic in mega-cap investing. Even when a company’s long-term product strategy remains intact, the market can rerate shares due to changes in sentiment, macro conditions, or expectations about the durability of services revenue and the performance of the broader Apple ecosystem. For Apple, that means periods of software momentum and ecosystem lock-in can help offset slower cycles in hardware upgrades, though the strength of that offset varies over time.

Still, the record here has limits. The referenced commentary does not lay out new, primary evidence about why Berkshire sold, such as a specific internal valuation change, a measured target for share count, or a documented shift in risk tolerance. Without that detail, it is hard to conclude whether Buffett’s team got “the” timing right or simply adjusted exposure for reasons that were rational at the time, such as concentration risk or a rebalancing of a broader portfolio.

Looking ahead, what matters most is whether WWDC updates translate into measurable business outcomes over the next several quarters, especially around software adoption and services performance. Investors will also watch for how Apple’s guidance and results align with its platform roadmap and whether the market continues to treat those steps as reinforcing the durability of Apple’s earnings power.
