But Berkshire's stock would double immediately if only Buffett would allow the company to be broken up, noted investor Ted O'Glove told CNBC on Thursday.
"There's 77 operating companies alone. Most of them could be spun off and within that, you'd have spinoffs of spinoffs," said O'Glove, author of "The Quality of Earnings," on "Closing Bell."
"All these companies have world-class management. That's why they were bought by Warren Buffett," he said. "They were doing very well on their own before. They would do very well on their own now."
However, analyst Tom Russo of Gardner Russo & Gardner disagreed. He noted that if Berkshire were to break up, it would no longer be able to reinvest funds from one company to another tax-free.
