TradingKey - On October 22 Eastern Time, amid a sell-off in AI-related stocks, Berkshire Hathaway (BRK.A)(BRK.B) reached another record high. As of press time, the company's stock rose 1.53% to $823,750.
The yields earned on the company's massive cash pile under higher short-term interest rates, along with the strong performance of major holdings such as Apple and Coca-Cola, may be key drivers behind the stock's rise.
Notably, over the past year, Berkshire Class B shares rose by about 10%, compared with a 15% gain in the S&P 500 Index over the same period. As the stock price climbed, the performance gap between the company and the broader market began to narrow.

Keefe, Bruyette & Woods analyst Meyer Shields believes that higher short-term U.S. interest rates are helping to boost Berkshire's stock price.
He noted that Berkshire still holds about $360 billion in cash, reflecting continued investment patience under the new CEO, while higher interest rates mean the company can earn more profit from these funds.
This means that while Berkshire waits for investment opportunities, its massive cash reserves can still generate substantial interest income. Higher short-term interest rates increase the yield on holding cash and provide support for market assessments of the company's profitability.
While maintaining a massive cash pile, new CEO Greg Abel has begun deploying a portion of the capital into acquisitions, equity investments, and share buybacks.
Since taking over, Berkshire has acquired homebuilder Taylor Morrison Home (TMHC) for $6.8 billion, invested $10 billion in Google parent Alphabet (GOOGL), and repurchased over $4.5 billion of its own stock.
These moves provide sources of return beyond interest income: acquisitions add operating assets, equity investments expand opportunities to participate in corporate growth, and buybacks reduce the number of shares outstanding, increasing the ownership stake of remaining shareholders.
For the stock price, this helps bolster investor confidence in management's capital allocation capabilities. Berkshire retains the financial firepower to await opportunities while also beginning to drive per-share value growth through actual deployment.
Berkshire's major holdings have also provided support for its rising stock price. Shares of Apple (AAPL) and Coca-Cola (KO) hit successive record highs, with Coca-Cola surpassing Alphabet to become its third-largest holding following a sharp rally. Meanwhile, its sixth-largest holding, Chevron (CVX), benefited from rising oil prices.
The gains in these holdings directly boosted the market value of the portfolio. Combined with interest income from cash reserves and new capital allocations, Berkshire's stock performance received support on multiple fronts.
Meanwhile, UBS raised its price target on Berkshire from $906,000 to $942,000, representing an increase of approximately 4%.
