Buffett's holdings lead with Apple, show high weight in financials

In his most recent letter to shareholders, dated Feb. 22, Warren Buffett disclosed the state of his company, Berkshire Hathaway, as well as its portfolio's largest equity positions. Among those, Apple was the largest position by market value at $76.7 billion. That position, with a reported cost basis of $35.3 billion, was built up by Mr. Buffett beginning in 2016 and makes up only 5.7% of Apple's $1.25 trillion valuation.

Financial companies were the most commonly held sector by Berkshire taking nine of the top 14 spots for a total $102.8 billion.

Berkshire Hathaway collected $3.798 billion in dividends from its 10 largest holdings. The positions in each holding accounted for $8.332 billion in retained earnings. While Berkshire's share of retained earnings is not paid out to investors and are usually reinvested in the company or used to repurchase stock. Mr. Buffett noted in his letter that share repurchases help strengthen its equity position.
