Berkshire Hathaway is a holding company with subsidiaries engaged in various business sectors, including insurance and reinsurance, railroad transportation, as well as utilities, energy production, and distribution.

In the third quarter, Berkshire Hathaway introduced positions in Domino's Pizza and pool supplies distributor Pool Corp. Both companies have underperformed relative to the broader market. Domino's Pizza faced challenges with low-income consumers affecting its stock price, while Pool Corp was affected by cautious discretionary spending, leading to tepid demand for swimming pools.

Recent regulatory filings revealed that during the third quarter, Berkshire Hathaway reduced its holdings in Apple, Bank of America, Ulta Beauty, and satellite radio company Sirius XM, among others. Its new investments included Domino's Pizza and Pool Corp. At the end of the third quarter, Berkshire's major holdings included Apple, American Express, Bank of America, Coca-Cola, and Chevron, with only Apple and Bank of America being subject to reductions among its top ten positions.

During the third quarter, Berkshire reduced its Apple holdings by 25%, with year-to-date reductions amounting to two-thirds of its initial stake. The Bank of America holdings were reduced by approximately 23%, with Berkshire maintaining a 10.4% stake at the end of the quarter. Notably, as holdings dipped below the 10% threshold, further disclosures are not required per SEC regulations. The reduction in Ulta Beauty was substantial, leading to a 96.5% decrease in holdings, which resulted in a 4% post-market decline for Ulta. Despite these adjustments, Berkshire's cash reserves soared to a historical high of $325.2 billion.

Speculation has emerged regarding the rationale behind reducing positions in high-valuation stocks like Apple and Bank of America, possibly to manage portfolio concentration. This, coupled with the absence of any stock buybacks and the addition of underperforming stocks like Domino's Pizza and Pool Corp, aligns with the prevailing perception that Warren Buffett views current U.S. stock valuations as elevated.

Following disclosure of investment changes, Berkshire's stock frequently reacts, highlighting investor confidence in Buffett's investment strategies.
