BRK.B RSI

What is BRK.B?

Berkshire Hathaway started as a struggling textile company in the 19th century, but everything changed in 1965 when Warren Buffett took control. He quickly pivoted the business model away from textiles and toward insurance, using the float from premiums to fund an aggressive acquisition strategy. Today, it is one of the world's largest conglomerates, operating as a massive holding company for an eclectic mix of businesses and a legendary portfolio of public stocks like Apple and Coca-Cola.

The core business model is brilliantly simple: the company owns several dozen subsidiaries that generate steady cash flow, which is then reallocated into higher-return opportunities. Its primary engine is insurance, led by GEICO and National Indemnity, which provides the liquid capital needed for expansion. Beyond insurance, Berkshire owns BNSF Railway, one of the largest freight networks in North America, and Berkshire Hathaway Energy, a leader in renewable and traditional utility services. Other recognizable brands under the umbrella include Dairy Queen, Duracell, and NetJets.

Historically, milestones include the 1996 issuance of Class B shares to make the company accessible to smaller investors and the 2010 acquisition of BNSF, which signaled a shift toward heavy infrastructure. Financially, Berkshire is a fortress. It consistently maintains a massive cash pile, often exceeding $150 billion, which acts as a safety net during market downturns and a war chest for acquisitions. Its earnings are diversified across cyclical and defensive sectors, providing unique stability.

Looking toward 2026, the strategic outlook focuses heavily on the leadership transition to Greg Abel. The company is expected to prioritize capital allocation efficiency, likely increasing share buybacks if major acquisitions remain overpriced. We will likely see a deeper push into renewable energy infrastructure and a continued modernization of GEICO’s underwriting technology to compete with digital-first insurers. While the post-Buffett era is a common talking point, the culture of decentralized management remains the bedrock of their 2026 strategy.

What is RSI?

The Relative Strength Index (RSI) is a momentum oscillator that measures the speed and magnitude of price changes. Developed by J. Welles Wilder, RSI ranges from 0 to 100 and helps traders identify overbought or oversold conditions in an asset.
