As of July 11, the number of BYD H shares in Citi seats reached 388.6 million, up about 225 million shares from last week, Hong Kong Stock Exchange (HKEX) data showed.

The change, which went viral on social media, sparked a lot of investor speculation about Warren Buffett's Berkshire Hathaway dumping its BYD holdings.

On September 29, 2008, Berkshire Hathaway Energy, which is 91.1 percent held by Berkshire, spent $230 million to buy 225 million shares of BYD at HK$8 each.

Since then, Berkshire's holdings in BYD have remained unchanged, and the latest move is seen as a prelude to Warren Buffett reducing his holdings in the largest Chinese new energy vehicle (NEV) maker.

As of March 31, 2022, Western Capital Group LLC, which is 100 percent owned by Berkshire Hathaway Energy, is BYD's fourth-largest shareholder, with a 7.73 percent stake.

After a lot of speculation triggered a plunge in the share prices, BYD said that the major shareholder's reduction in holdings requires an equity declaration, and the HKEX's equity disclosure platform did not show information on the reduction, according to a report in the Securities Times today.

BYD is currently operating everything normally, with all its businesses in order and NEV sales continuing to hit record highs, the company added.

According to the latest data from the HKEX, no recent declarations by shareholders of more than 5 percent have been found in the records of changes in the interests of BYD's major shareholders, including Berkshire.

However, it is worth noting that the Securities Times quoted an unnamed industry insider as saying that it is possible that Berkshire has not yet completed the process of reducing its holdings, so the data related to it is temporarily unavailable.

There is also a possibility that Buffett lent his holdings to hedge funds for shorting, according to the report.
