Warren Buffett's Berkshire Hathaway has finally unveiled a major stake in the insurance company Chubb, a mystery that had been kept under wraps since last year. The disclosure came through a Securities and Exchange Commission filing, revealing that Berkshire acquired nearly 26 million shares of Chubb, amounting to a value of approximately $6.7 billion.
Chubb, a global insurance business operating in 54 countries, gained attention earlier this year for underwriting President Donald Trump's appeal bond in a defamation lawsuit. The news of Berkshire's investment caused Chubb's stock to surge by over 8% in after-hours trading.
