Berkshire Hathaway Inc. New (BRK-B)

Executive Summary

BRK-B has rebounded 2.93% since the August 17 report, recovering from $501.13 to $515.81 and approaching the $517 level that flipped from support to resistance in mid-August. The recovery is underpinned by confirmation of Berkshire's Q2 pivot toward active capital deployment under CEO Greg Abel — including a $36.6 billion Alphabet stake and the $6.8 billion Taylor Morrison acquisition — alongside a bullish revaluation of the Precision Castparts unit. Despite this rebound, BRK-B still trails the S&P 500 by over 10 percentage points YTD, keeping the underperformance narrative from prior reports largely intact.

Key Updates

Since the August 17 report ($501.13), BRK-B has risen 2.93% to $515.81, reversing part of the post-earnings decline previously flagged. Year-to-date performance stands at +2.62%, a modest improvement from the +0.5% level referenced in the August 29 CNBC piece, though the stock continues to lag the S&P 500 by a wide margin. The most significant new development is a Barron's-cited valuation of the Precision Castparts unit at approximately $100 billion — nearly three times Berkshire's $37.2 billion 2016 purchase price — based on GE Aerospace's recent $11.75 billion acquisition of a comparable at 26x projected 2027 EBITDA, driven by AI data-center-linked demand for turbine components. Additionally, Q2 13F disclosures confirm Berkshire ended a 14-quarter equity-selling streak, becoming a net buyer of $19.8 billion in stocks, with Alphabet now its third-largest holding ($36.6–$37.8 billion) and continued additions to Delta Air Lines and Lennar. Cash reserves fell to $365.5 billion from a record $397 billion, and the Gates Foundation trimmed its BRK-B position by roughly 2.4 million shares.

Current Trend

BRK-B's YTD gain of +2.62% remains well below broader market performance, consistent with the underperformance theme identified in the August reports. Short-term momentum has turned positive across all measured windows: +1.07% (1d), +1.93% (5d), +2.34% (1m), and +5.26% (6m), indicating a recovery from the early/mid-August pullback that had broken below the $517 support level. The stock is now testing that same $517 level from below, which previously acted as support before the post-earnings breakdown and now represents the immediate resistance to watch for confirmation of a trend reversal.

Investment Thesis

Berkshire's thesis rests on its diversified conglomerate structure — insurance float, wholly owned operating businesses, a large public equity portfolio, and substantial dry powder for opportunistic capital deployment. Under new CEO Greg Abel, the thesis has shifted toward execution risk: whether management can productively deploy the historically large cash pile into value-accretive acquisitions and equity purchases. The Precision Castparts revaluation illustrates the potential for long-dated industrial bets to compound significantly, reinforcing Berkshire's buy-and-hold, intrinsic-value approach even through periods of write-downs and market skepticism.

Thesis Status

The thesis is partially validated by recent developments. Berkshire's Q2 turn to net equity buying ($19.8 billion), the Taylor Morrison acquisition ($6.8 billion), and increased stakes in Alphabet and Delta demonstrate that Abel is actively deploying capital, addressing a key investor concern raised in prior reports. The Precision Castparts revaluation further supports the long-term value-creation narrative central to Berkshire's investment case. However, the cash position remains elevated at $365.5 billion, no dividend has been introduced, and the stock's continued YTD underperformance versus the S&P 500 indicates the market has not yet fully rewarded these actions. The thesis therefore remains intact but unconfirmed by price action, with execution credibility under Abel still the primary swing factor.

Key Drivers

Recent price action has been shaped by several factors: the Precision Castparts unit's estimated ~$100 billion valuation on AI-driven turbine component demand (CNBC); confirmation that Berkshire ended its 14-quarter equity-selling streak with $19.8 billion in net purchases, headlined by a $36.6–$37.8 billion Alphabet stake (Forbes, Fortune); the $6.8 billion Taylor Morrison acquisition and expanded Delta Air Lines position ($5.37 billion) (Fortune); continued investor concern over Abel's transition, the lack of dividends, and the still-substantial $365.5 billion cash pile (CNBC); and the Gates Foundation's reduction of its BRK-B stake (Fortune).

Technical Analysis

BRK-B has recovered 2.93% from the $501.13 level flagged in the August 17 report, now trading at $515.81 and approaching the $517 resistance level established after the post-earnings breakdown. All short-term momentum indicators are positive (1d +1.07%, 5d +1.93%, 1m +2.34%), suggesting building upward pressure, while the 6-month gain of +5.26% indicates the broader uptrend from earlier in the year remains intact despite the August pullback. A sustained close above $517 would be required to confirm a technical trend reversal and open the path toward retesting prior highs; failure to clear this level could result in continued range-bound consolidation between $500 and $517.

Bull Case

• Precision Castparts is now estimated to be worth approximately $100 billion, nearly triple Berkshire's $37.2 billion purchase price, driven by AI-data-center-related demand for turbine components — a strong proof point for long-term value creation (CNBC).
• Berkshire ended a 14-quarter equity-selling streak in Q2, becoming a net buyer of $19.8 billion in stocks, signaling renewed confidence in deploying capital (Forbes).
• Continued active capital deployment under Abel includes the $6.8 billion Taylor Morrison acquisition and an increased $5.37 billion Delta Air Lines stake (Fortune).
• A new $36.6–$37.8 billion Alphabet position, including a $10 billion AI-related commitment, is now Berkshire's third-largest holding, reflecting conviction in high-growth technology exposure (Forbes).
• Berkshire repurchased $4.5 billion of its own shares in Q2, indicating management views the stock as undervalued (CNBC).

Bear Case

• BRK-B continues to underperform the S&P 500 by over 10-12 percentage points YTD, reflecting persistent investor skepticism despite recent capital deployment (CNBC).
• Uncertainty around new CEO Greg Abel's strategy and execution capability remains a key overhang on the stock (CNBC).
• Cash reserves remain historically elevated at $365.5 billion despite the Q2 reduction, and the absence of dividend payments continues to disappoint income-oriented investors (CNBC).
• Berkshire has yet to execute a major acquisition exceeding $100 billion, raising doubts about the company's ability to deploy capital at scale (CNBC).
• The Gates Foundation reduced its BRK-B holding by nearly 2.4 million shares, potentially signaling diminished conviction from a long-term institutional holder (
