Warren Buffett's Berkshire Hathaway on Monday revealed a new stake inApple, in a bet that the stock's price could rebound after iPhone sales fell for the first time.
Berkshire held 9.81 millionAppleshares worth $1.07 billion as of March 31, according to a filing with the U.S. Securities and Exchange Commission detailing the company's U.S.-listed stock holdings.
It is not clear who made the investment, Buffett or one of his portfolio managers, Todd Combs and Ted Weschler, who each invest about $9 billion.

Buffett has said he typically makes Berkshire's multibillion-dollar investments, while Combs and Weschler make smaller wagers.
The investment inApplemay have been made with money from the sale of AT&Tstock.
Berkshire held $1.6 billion of AT&T at year's end but listed no investment in the phone company in Monday's filing.
Appleshares, which were up 1.4 percent in premarket trading at $91.81, are nearly one-third below their record high last April. They are also well below their price level at the end of March.
TheApplestake deepens Berkshire's commitment to the technology sector, which Buffett has long shunned, apart from a big stake in International Business Machines Corp. He has long said he does not understand the tech sector well enough.
On Monday, Buffett confirmed to CNBC that he offered to help Dan Gilbert, the chairman of Quicken Loans and owner of the Cleveland Cavaliers basketball team, finance a bid to acquire Yahoo.
Reuters first reported Buffett's support on Friday.
Last month, billionaire activist investor Carl Icahn revealed that he had sold his entire stake inApple, citing the risk of China's influence on the stock.
