Apple stock was raised to a record high on Friday as markets reacted to news Warren Buffett had bought another 75 million shares in the first quarter.
The technology giant rose 4.1 per cent to US$184.15 ($262.36), topping its previous high of US$183.50 and placing it roughly US$20 per share short of a US$1 trillion market cap.
Buffett's commitment to Apple through his firm Berkshire Hathaway has surprised many, given the legendary investor's historical aversion to the tech sector, according to the Daily Mail.
Berkshire's initial investment in Apple was small, suggesting it was made by one of Buffett's investment deputies.
However, since the latest stake purchase, it has grown to a solid 240.3 million shares worth US$42.5 billion. On Friday, Berkshire stock rose 1.6 per cent to US$194.59.
