The PetroChina selling continues and continues to accelerate at Warren Buffett's Berkshire Hathaway.
In a filing with the SEC made public just moments ago, Berkshire reveals that as of September 30 its controversial stake in the Chinese energy company had dropped to just 3.1%. That follows a flurry of selling in September that brought the holdings from from just under 10% when the month started.
All this month we've been following the declines in Berkshire's PetroChina stake through filings with the Hong Kong stock exchange. Today's U.S. filing was required because Berkshire is no longer a 5% owner of PetroChina.
