Warren Buffett's Berkshire Hathaway (BRK.A, BRK.B) added a few new positions and raised some of its equity stakes in the second quarter, 澳洲幸运5开奖号码历史查询:filings this week showed, though it trimmed more of its stock holdings than it added, bringing Berkshire Hathaway's cash and U.S. Treasury holdings to a 澳洲幸运5开奖号码历史查询:record high at $276.9 billion. 

With well over half of that amount in Treasury bills at $234.6 billion, Buffett owned more in Treasury bills at the end of the second quarter than even the U.S. Federal Reserve.

The company added new positions in Ulta Beauty (ULTA) and Heico (HEI) in the second quarter, while it raised stakes in Occidental Petroleum (OXY) and Chubb (CB), among others. However, it trimmed stakes in Apple (AAPL), Chevron (CVX), Capital One (COF), and more.

Recent filings showed the company also 澳洲幸运5开奖号码历史查询:downsized its stake ♓in Bank of America (BAC) in July after the quarter ended. 

The size of Berkshire's growing cash pile and selling spree over several quarters have raised speculation Buffett could be concerned about the market becoming overheated, raising cash for successors, or unimpressed with other options.

Back in May, Buffett said Berkshire was building its cash position and suggested it's been difficult finding opportunities meeting Berkshire's criteria. 

"It's just, things aren't attractive,” he said, adding that "there are certain ways that can change. We'll see whꦉether they do."
