Warren Buffett Is Buying a Secret Stock Again -- and Based on Clues, This Is the Company I Believe He's Building a Position In
For the first time since 2023, the Oracle of Omaha is using the confidential tag to build a stake in a company without investors knowing which stock it is.

There's perhaps no event more anticipated by investors than the quarterly unveiling of what Berkshire Hathaway's (NYSE: BRK.A)(NYSE: BRK.B) mastermind CEO Warren Buffett has been up to on the investing front.
No later than 45 calendar days following the end to a quarter, institutional investors with at least $100 million in assets under management (AUM) are required to file Form 13F with the Securities and Exchange Commission. A 13F provides investors with a concise snapshot of what Wall Street's leading money managers have been buying and selling. With the Oracle of Omaha overseeing nearly $287 billion in AUM at Berkshire Hathaway, his company is absolutely required to file a 13F.
The filing deadline for first-quarter trading activity was May 15 -- and Buffett's company has a knack for filing its 13F after the closing bell on the deadline day.
