Warren Buffett's Berkshire Hathaway has fully exited its position in Chinese electric vehicle maker BYD Company, ending a 17-year investment that generated staggering returns. The investment firm began selling BYD shares in 2022 after a massive run-up in share price and recently completed the divestment, according to SEC filings. Berkshire's initial $230 million investment in 2008 for roughly 225 million shares, representing about 10% of the company at the time, had increased in value by approximately 3,890% over the holding period.

The timing of Berkshire's exit coincides with challenging market conditions for BYD in its home market. The Chinese automaker has seen domestic sales, which account for roughly 80% of its global shipments, decline for four consecutive months as of August. In response to these market pressures, BYD has reduced its annual sales target by as much as 16%, down to 4.6 million vehicles. These developments come despite BYD's remarkable growth trajectory that saw it quickly dominate China's EV market before expanding globally.

BYD has maintained competitive advantages through vertical integration and technological innovation. The company has developed cheaper electric vehicles than competitors like Tesla while offering more powerful charging capabilities. Earlier this year, BYD released EV charging technology capable of adding nearly 250 miles of range in approximately five minutes. These innovations contributed to BYD surpassing Tesla in annual revenue with roughly $107 billion in 2024, while capturing 32% of China's EV market compared to Tesla's 6.1%.

The Chinese EV market has become increasingly competitive, prompting BYD to implement aggressive pricing strategies. The company recently launched two new electric versions of its Qin Plus EV sedan with prices starting as low as the equivalent of $19,200, representing a reduction of over $4,000 from its initial launch price of $23,500 in early 2024. This follows broader price cuts across multiple battery electric and plug-in hybrid models in China, with some models reduced by up to 30%. Despite these challenges, BYD has announced expansion plans targeting half of its sales to come from outside China by 2030.

Families of the 29 victims killed in the 1994 Chinook helicopter crash are escalating their decades-long fight for answers, preparing to deliver a petition with more than 47,000 signatures to Downing Street demanding a public inquiry. The Chinook Justice Campaign has published 110 "critical questions" they want answered about the tragedy that claimed the lives of 25 intelligence experts and four special forces crew members when the aircraft crashed on the Mull of Kintyre on June 2, 1994.

The campaign comes after Prime Minister Sir Keir Starmer rejected calls for a judge-led inquiry into the incident, prompting families to declare they will "see the UK government in court." Among those delivering the petition on Tuesday are brothers Andy and Matt Tobias from Watford, whose father John Tobias was killed in the crash. The petition delivery will be accompanied by an attempt to deliver a letter directly to the Ministry of Defence.

Central to the families' concerns are questions about mission authorization, aircraft selection, and whether those on board were properly warned of risks. The campaign has gained momentum amid revelations that key documents related to the crash have been sealed until 2094—a century after the incident occurred. David Hill, technical expert for the Chinook Justice Campaign, characterized the government's position as "a betrayal by the state of them and their loved ones."

The crash investigation has followed a contentious path over the past three decades. Initial findings blamed pilot error for the tragedy, but this conclusion was overturned in 2011. The continuing secrecy surrounding the incident has drawn criticism from campaigners who argue it "undermines trust not only in the MoD but in the government itself." As families prepare to confront the government directly, the case represents one of Britain's longest-running military accountability battles.
