Two years after purchasing 10 million shares of Apple then-valued at $1.1 billion — and with numerous incremental additions since — Warren Buffett's Berkshire Hathaway's stake in the company is now worth nearly $50 billion, CNN reports, citing a regulatory filing.
Why it matters: Earlier this week, Apple became the first-ever U.S. company to have its market cap hit $1 trillion. Berkshire's stake in Apple is the largest of its substantial investment portfolio.
Correction: This article has been updated to note that Berkshire purchased stock multiple times after its purchase two years ago.
