Performance lens

A holding-company view

Track the compounding, not just the quote.

BRK.B tends to attract shareholders who care about multi-year business performance, book value trends, operating earnings, cash levels, and insurance float. This site keeps the quote visible while giving the long view equal weight.

Watch valuation with restraint.

Use market price alongside Berkshire's reported fundamentals. Public filings, annual reports, repurchase commentary, and operating earnings are better anchors than intraday moves.

Stay independent.
