Even when losing, Berkshire Hathaway's Warren Buffett is secretly winning.
Shares of the billionaire's conglomerate rose to a new high on Tuesday after S&P Global Ratings said the company is no longer at risk of a credit rating downgrade. Berkshire A shares hit $270,960, and B shares rose to $180.61, both all-time highs, according to FactSet data.
S&P affirmed Berkshire's AA rating and a stable outlook. Berkshire had been on review since July, after bidding $9 billion in cash for the Texas power transmission operation of Energy Future Holdings. But in a bizarre (for Buffett, at least) three-way bidding war for the company, called Oncor, Sempra Energy emerged the victor over the weekend, with a $9.45 billion offer.
