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.

A major outage at Amazon Web Services has disrupted operations for numerous popular applications and platforms globally, affecting millions of users. The cloud computing infrastructure failure began early Monday morning, with users reporting widespread issues accessing services including Snapchat, Duolingo, Zoom, and various gaming platforms. Amazon confirmed it was investigating increased error rates and latency across multiple AWS services, though the company has not yet identified the root cause of the system failure.

The disruption appears to have originated with servers hosted in the US-EAST-1 region, according to initial reports. This triggered a cascade effect that impacted AWS infrastructure supporting millions of websites and applications worldwide. Downdetector, a platform that monitors service outages, reported receiving over four million problem reports in a single morning—more than double the typical weekly volume—indicating the scale of the disruption across affected services.

Among the services experiencing significant operational problems are communication platforms like Zoom, Signal, and Slack; gaming services including Roblox, Fortnite, and PlayStation Network; social media applications such as Snapchat; and financial services from banks including Lloyds and Bank of Scotland. Streaming platforms Prime Video and Crunchyroll, along with educational tool Duolingo and design platform Canva, have also been affected by the cloud service failure.

The outage has manifested differently across regions, with Amazon's own websites remaining operational in Europe while still experiencing service-specific errors. AWS engineers are actively working to mitigate the issues and restore normal operations. The company has committed to providing regular updates as they work to resolve the widespread service disruption that has highlighted the internet's heavy reliance on cloud infrastructure providers.
