Berkshire Hathaway (BRK.A/BRK.B) represents the ultimate value investing vehicle — a collection of exceptional businesses assembled over six decades by Warren Buffett, the greatest investor in history.

This comprehensive analysis examines Berkshire's intrinsic value, competitive advantages, growth prospects, and the key factors that will determine its future performance. Using Moatifi's framework for analyzing conglomerates, we'll break down each business segment and assess whether BRK deserves a place in your portfolio.
