Back in 2018, Apple CEO Tim Cook told Buffet that he would fly up to Omaha to help Buffet set up his iPhone whenever he decided to switch. Not everyone can get their iPhone set up by the CEO of the company, but it helps to own 245 million shares of Apple worth $72 billion according to filings made by Buffet’s holding company at the end of last year. Cook even sent Buffet a new iPhone, one of several that he has received. It must be nice to be worth $90.3 billion but still have people send you free iPhone models.

Buffet’s holdings took a big hit today when the stock market dropped sharply due to the spread of the coronavirus disease. With Apple’s stock closing under $300 on Monday for the first time since January 7th, the decline of $14.87 a share dropped the value of Berkshire Hathaway’s Apple shares by $3.42 billion. But for one of the world’s richest men, it is no cause for alarm.
