Berkshire Hathaway’s (BRK.B) new mystery stock is expected to be revealed in a regulatory filing on Aug. 14.

Speculation on Wall Street and social media is that the holding company run by Warren Buffett has invested about $5 billion in a publicly traded industrial company. The name of the new stock was hidden in the regulatory reports that Berkshire Hathaway filed in this year’s first and second quarters. Buffett often requests to shield the name of a new stock he is building a stake in to prevent other investors from mimicking his moves and pushing share prices higher. However, the name of the latest mystery stock is now expected to be revealed as the U.S. Securities and Exchange Commission (SEC) requires Berkshire Hathaway to disclose all of its U.S.-listed equity holdings at mid‑year (June 30).

**Other Portfolio Changes**

Berkshire Hathaway typically waits until the last possible day to make its 13F regulatory filing with the SEC, which would be Aug. 14. Analysts say the new filing could show that Buffett made further sales of Bank of America (BAC) stock after reducing its stake in the lender by nearly 40 % since July 2024. Berkshire Hathaway’s most recent mystery stock turned out to be insurer Chubb (CB), which it hid from view in late 2023 and early 2024 as it accumulated a $7 billion stake in the Swiss insurance company. Warren Buffett also sought confidential treatment when he was first buying shares of oil major Chevron (CVX) and telecommunications giant Verizon Communications (VZ).

**Is BRK.B Stock a Buy?**

Only one analyst currently offers a rating and price target on Berkshire Hathaway’s more affordable class B stock. So instead, we’ll look at the stock’s three‑month performance. As one can see in the chart below, shares of BRK.B have declined 9.21 % in the last 12 weeks.
