A Lost iPhone Story That Became Berkshire Hathaway’s Biggest Bet: Apple’s Decade-Long Run

Warren Buffett’s decision to build a massive stake in Apple (NASDAQ: AAPL) reportedly traces back to an unlikely moment: a close friend’s distress upon believing he had misplaced his iPhone. That glimpse into the device’s grip on its users helped spark what became the single largest equity holding at Buffett’s Berkshire Hathaway (NYSE: BRKA) (NYSE: BRKB).

After first buying in 2016, Buffett steadily escalated the position until Apple sat at the top of Berkshire’s equity portfolio. At its peak influence, Apple’s appreciation had swelled the stake to represent roughly 40% of the conglomerate’s entire stock portfolio’s value — a remarkable concentration for an investor long skeptical of technology companies.

The Decade in Numbers

The payoff from that conviction has been substantial. According to the original analysis, a $10,000 investment in Apple a decade ago would be worth approximately $122,400 today — a more than twelvefold increase.

Apple’s stock currently trades at $332.27, up 1.99% from the previous close of $325.80. The company commands a market capitalization of about $4.60 trillion, underscoring its position among the most valuable companies in the world. Operating in the consumer electronics industry, Apple designs and sells the iPhone, Mac computers, iPad tablets, wearables, and a range of accessories globally.

Why the iPhone Anecdote Matters

The story illustrates Buffett’s well-documented investment philosophy: rather than analyzing technical specifications, he focused on the stickiness of Apple’s ecosystem and the emotional attachment users have to their devices. A product that provokes visible distress when lost, in his view, signaled durable consumer loyalty and pricing power — qualities he historically sought in consumer brands.

Apple also proved to be a fitting match for Berkshire’s structural preferences. The company runs enormous buyback programs, which quietly increase Berkshire’s effective ownership stake over time without additional purchases, and generates service revenue that complements its hardware base.

What to watch

• Apple’s upcoming quarterly earnings report, including iPhone sales trends and services revenue growth.
• Any disclosure changes in Berkshire Hathaway’s 13F filings regarding the size of its Apple position.
• Apple product announcements and new category launches that could shape its next growth phase.
• Continued share repurchase activity, which affects Berkshire’s proportional stake.
