Berkshire Hathaway‘s monstrous cash pile topped $300 billion in the third quarter as Warren Buffett continued his stock-selling spree and held back from repurchasing shares.

The Omaha-based conglomerate saw its cash fortress swell to a record $325.2 billion by the end of September, up from $276.9 billion in the second quarter, according to its earnings report released Saturday morning.

The mountain of cash kept growing as the Oracle of Omaha sold significant portions of his biggest equity holdings, namely Apple and Bank of America. Berkshire dumped about a quarter of its gigantic Apple stake in the third quarter, making the fourth consecutive quarter that it has downsized this bet. Meanwhile, since mid-July, Berkshire has reaped more than $10 billion from offloading its longtime Bank of America investment.

Overall, the 94-year-old investor continued to be in a selling mood as Berkshire shed $36.1 billion worth of stock in the third quarter.

No buybacks

Berkshire didn’t repurchase any company shares during the period amid the selling spree. Repurchase activity had already slowed down earlier in the year as Berkshire shares outperformed the broader market to hit record highs.

The conglomerate had bought back just $345 million worth of its own stock in the second quarter, significantly lower than the $2 billion repurchased in each of the prior two quarters. The company states that it will buy back stock when Chairman Buffett “believes that the repurchase price is below Berkshire’s intrinsic value, conservatively determined.”

Class A shares of Berkshire have gained 25% this year, outpacing the S&P 500’s 20.1% year-to-date return. The conglomerate crossed a $1 trillion market cap milestone in the third quarter when it hit an all-time high.

For the third quarter, Berkshire’s operating earnings, which encompass profits from the conglomerate’s fully-owned businesses, totaled $10.1 billion, down about 6% from a year prior due to weak insurance underwriting. The figure was a bit less than analysts estimated, according to the FactSet consensus.

Buffett’s conservative posture comes as the stock market has roared higher this year on expectations for a smooth landing for the economy as inflation comes down and the Federal Reserve keeps cutting interest rates. Interest rates have not quite complied lately, however, with the 10-year Treasury yield climbing back above 4% last month.

Notable investors such as Paul Tudor Jones have become worried about the ballooning fiscal deficit and that neither of the two presidential candidates squaring off next week in the election will cut spending to address it. Buffett has hinted this year he was selling some stock holdings on the notion that tax rates on capital gains would have to be raised at some point to plug the growing deficit.
