Origin: 9 to 5 Mac — Warren Buffett praises AAPL stock in annual letter, Berkshire’s stake now valued at $120 billion
Read Warren Buffett’s annual letter to Berkshire Hathaway shareholders

Berkshire first began acquiring Apple stock in late 2016 and it currently holds $120 billion worth of the stock, at a cost of $31.1 billion.

Berkshire’s investment in Apple vividly illustrates the power of repurchases. We began buying Apple stock late in 2016 and by early July 2018, owned slightly more than one billion Apple shares (split-adjusted).

When we finished our purchases in mid-2018, Berkshire’s general account owned 5.2% of Apple.

Buffett also says that Berkshire sold a small portion of its AAPL stake at the end 2020, pocketing $11 billion. Because of Apple’s buybacks, however, which reduce the total number of outstanding shares, Berkshires ownership of AAPL has increased to 5.4% despite that sale: 

Since then, we have both enjoyed regular dividends, averaging about $775 million annually, and have also – in 2020 – pocketed an additional $11 billion by selling a small portion of our position.

Despite that sale – voila! – Berkshire now owns 5.4% of Apple. That increase was costless to us, coming about because Apple has continuously repurchased its shares, thereby substantially shrinking the number it now has outstanding.

This also has benefits for Berkshire shareholders, Buffett explains in the letter:

But that’s far from all of the good news. Because we also repurchased Berkshire shares during the 21⁄2 years, you now indirectly own a full 10% more of Apple’s assets and future earnings than you did in July 2018.

As Bloomberg reports, Buffett resisted buying Apple stock for years because he said he failed to understand the technology company. Working with investing deputies Todd Combs and Ted Weschler, however, Berkshire expanded and has also since added other technology companies such as Amazon and Verizon.
