Berkshire Hathaway Inc. (BRK-B) Insider, 13F Hedge Fund & Politician Buy/Sell Thermometer

Per the Roarable RQD rating, BRK-B scores 76 out of 100, a letter grade of B+, labeled "Roarable Buy — Very Good Cash & Smart-Money Inflow." The five pillars are: Fundamental Cash Engine at 13/20 (ROIC 11.5%; FCF yield 2.09%), Whale 13F Flow at 17/20 (institutional accumulation and options positioning), Insider Conviction at 15/20 (SEC Form 4 and Congressional PTR cluster flow), Macro Regime Fit at 15/20 (Beta 0.61; sector sensitivity), and Forensic Balance Sheet at 16/20 (Altman Z 2.85; Piotroski F 4/9; Debt/Equity 0.5). The strongest pillar is institutional flow, while the Fundamental Cash Engine is the weakest, largely because the stated FCF yield of 2.09% is modest relative to the stock's price. For a prospective investor, the rating points to strong institutional demand and a conservative balance sheet, with the cash-generation pillar as the main reason to weigh valuation carefully. Per the market data, the forward P/E of 24.3 sits well above the trailing P/E of 13.5, meaning the stock's earnings-based valuation depends heavily on which earnings base an investor believes. The rating is an educational summary of source-derived scores, not personalized financial advice.

Two are marked as catalysts or green-light signals: a 24/7 Wall St. report stating that Berkshire bet another $330 million on one stock, which soared 41%, and a Yahoo Finance report on the company's historical founding investment. Several market-wire items discuss whether the company has begun deploying its cash and whether a Class A stock split may be coming. The valuation debate is present across multiple headlines, with one piece questioning whether 24 times earnings is fair and another asking whether the stock is a buy near its all-time high. No proprietary signals are present in the butterfly graph. The news wire does not specify the magnitude or timing of any of these events beyond what is quoted.
