**Chubb Stock Soars After Warren Buffett’s Berkshire Hathaway Reveals “Mystery Stock” Purchase**

Omaha, Nebraska – Warren Buffett’s investment firm, Berkshire Hathaway, made a significant move by opening a new position in Chubb, a multinational property and casualty insurer. This development was revealed in a 13F filing on Wednesday, which unveiled the “mystery stock” that had caught the attention of investors in recent months. As a result of this news, Chubb’s stock experienced a surge in after-hours trading.

According to the 13F filing, Berkshire Hathaway purchased nearly 26 million shares of Chubb, amounting to a total of $6.7 billion. While the Chubb position was officially disclosed in Berkshire’s Q1 filing, the conglomerate had been discreetly acquiring shares of the insurance company in previous quarters, keeping the identity of the stock under wraps until now.

In addition to the Chubb acquisition, Berkshire Hathaway made several other notable moves in Q1, including completely divesting its stake in HP and reducing its holdings in Apple and Paramount Global. Meanwhile, the company also adjusted its positions in Chevron and Occidental Petroleum, as detailed in its Q1 earnings report released on May 4.

Reports of Berkshire Hathaway’s confidential stock purchases had been circulating since late last year, with investors eager to uncover the mystery behind the acquisitions made in Q3 and Q4 of 2023. Chubb’s addition to Berkshire’s portfolio aligns with the conglomerate’s existing interests in the insurance industry, which include subsidiaries like Geico and General Re.

Following the news of Berkshire’s investment in Chubb, the insurer’s stock saw a notable 5.5% increase in late trading on Wednesday. While Berkshire made exits from several financial stocks in 2023, it maintains significant stakes in companies like Bank of America, positioning itself as a key player in the finance sector.

As Berkshire Hathaway continues to make strategic moves in its investment portfolio, the market response to its acquisitions and divestments will be closely monitored by investors and analysts. With Warren Buffett at the helm, Berkshire’s decisions carry significant weight in the financial world, influencing market trends and investor sentiment.
