Key Points
Berkshire Hathaway (NYSE: BRKA)(NYSE: BRKB) is a remarkably diversified industrial conglomerate, yet it is classified as a finance company because of its extensive insurance operations. This classification is critical when assessing the nearly $400 billion in cash on its balance sheet, which serves as a safety net and provides flexibility for strategic investments. However, the business model is fundamentally driven by the insurance float rather than the cash itself.
What Does Berkshire Hathaway Do?
From a broad perspective, Berkshire Hathaway operates across multiple sectors. Former CEO Warren Buffett largely functioned as a global capital allocator, viewing the company as his personal investment vehicle. Purchasing Berkshire shares was effectively a way to gain exposure to Buffett’s investment decisions. The current large cash reserve is a by‑product of the company’s extensive float and is unrelated to Buffett’s long‑term success.

The true strength of Buffett’s strategy lies in his recognition that the float can be channelled into equity and acquisition opportunities. While insurance premiums generate cash that must eventually be paid out as claims, leading most insurers to adopt conservative bond‑heavy portfolios, Buffett applied a more aggressive stance to generate superior returns without jeopardising the float’s integrity.
His approach has involved acquiring well‑managed companies at moderate valuations and holding them for the long term. Core equity holdings include Coca‑Cola (NYSE: KO) and American Express (NYSE: AXP).
Berkshire Hathaway’s Story Continues
Buffett stepped down as CEO at the close of 2025, handing the reins to Greg Abel, a long‑time associate. Buffett remains chairman, ensuring continuity and strategic oversight. The substantial cash reserve will serve as a cushion for Abel as he steers the company forward.
Despite the leadership transition, Berkshire’s core framework—leveraging insurance float—remains unchanged. The model has inspired other firms, notably Markel Group (NYSE: MKL) and Brookfield Corporation (NYSE: BN), who have adopted investment‑led insurance strategies.
Should You Consider Investing in Berkshire Hathaway?
Potential investors should evaluate Berkshire Hathaway within the broader context of their portfolio strategy. While it may not feature in every top‑ten list, its disciplined capital allocation, deep operational experience, and robust float‑driven investment engine make it a compelling long‑term holding.
