Berkshire Hathaway (BRKA.VI) Stock Analysis & Winston Score

Berkshire Hathaway is a giant holding company run by Warren Buffett that owns dozens of well-known businesses across many industries. Its biggest pieces include GEICO (car insurance), BNSF Railway (one of the largest freight railroads in the US), and Berkshire Hathaway Energy, plus a huge collection of consumer brands like Dairy Queen, Duracell, and See's Candies. It also holds massive stock investments in companies like Apple, Coca-Cola, and American Express. The company makes money in two main ways: operating profits from its owned businesses and investment income from its enormous stock and bond portfolio. Berkshire operates primarily in the United States but has international investments and subsidiaries as well. Its main competitive advantage is its massive "float" — money collected from insurance premiums that it can invest before claims are paid. The biggest risk going forward is leadership succession, since Warren Buffett, now in his mid-90s, has been the central decision-maker for over five decades.
