Berkshire trimmed a quarter of its remaining stake in Apple, bringing its investment in the iPhone maker to $69.9 billion. It was the fourth consecutive quarter of cuts to Berkshire’s holdings in Apple, which are now down by almost two-thirds from the $174.3 billion it owned at the start of the year. Berkshire halved its Apple stake in the second quarter.

But Buffett has signaled that he doesn’t plan to ever let go of his Apple stake altogether. During a question-and-answer session with Buffett at Berkshire’s annual shareholder conference in May, the 94-year-old investor said it’s “extremely likely” Apple remains Berkshire’s largest common stock holding — and that it will stay that way unless something dramatic happens.
