Berkshire Hathaway Inc (BRK.B)

[Prudent Capitalist]

As AAPL's largest shareholder BRK reaped a huge gain on Friday with AAPL shares closing +10.47%. As of 12/31/19 BRK held well over 250.86 Million shares of AAPL, so Friday's gain of $40.28 per AAPL share meant a gain of around $10.1 Billion for BRK. And, that is assuming BRK did not grow its AAPL share position and ownership when AAPL shares dropped earlier this year.
