Berkshire Hathaway’s longtime edge over S&P 500 shows signs of eroding

Berkshire Hathaway is lagging the S&P 500, with shares down about 4% year to date versus the index's 9% gain, and a 22V Research chart showing the stock has reverted to relative levels last seen around 2007. The article highlights headwinds from Berkshire's lack of exposure to AI-led market winners, its nearly $400 billion cash pile, and only modest buybacks under Greg Abel. While Berkshire remains near record highs and still has a strong long-term record, the message is that sustained outperformance versus the broader market may be harder to achieve going forward.

Analysis

The key setup is not that Berkshire is “cheap” or broken; it is that the stock is migrating from a quality compounder into a quasi-bond proxy with equity upside limited by scale. Once a mega-cap grows this large, the marginal source of alpha shifts from business compounding to capital allocation, and the current cash balance effectively caps near-term multiple expansion because investors start underwriting a lower ROE on excess liquidity.

That creates a second-order winner set: the market’s AI beneficiaries are becoming the natural relative-growth sink for capital that used to hide in Berkshire as a defensive compounder. If Berkshire continues to lag while holding a massive cash buffer, any incremental buyback restraint will reinforce underperformance because it signals management is preserving optionality instead of forcing return of capital; that is usually bullish for holders waiting for a drawdown, but bearish for relative performance during a melt-up. The AAPL stake matters less as a driver of upside than as a reminder that Berkshire’s equity beta is still partly tethered to a single mature mega-cap rather than the AI capex complex.

The risk is that the technical underperformance becomes self-reinforcing over the next 3-6 months: passive and factor allocators may reclassify BRK.B from “steady compounder” to “late-cycle defensive,” reducing incremental demand as long as the tape remains risk-on. The contrarian case is that this is setting up a very good entry point for long-duration capital: if markets suffer even a 7-10% drawdown, Berkshire’s cash and balance-sheet optionality should outperform almost immediately, and the stock could rerate faster than the broader market because investor psychology flips from “dead money” to “dry powder.”

Key Decisions for Investors

• Short-term relative-value trade: long QQQ / short BRK.B for 1-3 months, sized modestly. Thesis is continued AI-led leadership and weak capital deployment at Berkshire; risk/reward worsens if the market corrects >5%, so use a tight stop on BRK.B strength.
• For hedged long-only books, rotate a portion of defensive mega-cap exposure from BRK.B into cash-rich AI infrastructure beneficiaries over the next 4-8 weeks. Prefer names with visible capex linkage and stronger momentum; Berkshire’s opportunity cost is highest in a risk-on tape.
• Buy BRK.B on a 5-8% pullback as a medium-term hedge against a volatility event. The cleanest expression is a staggered entry or 3-6 month call spread financed against strength in momentum names.
• Monitor buyback cadence closely over the next two quarters; if repurchases remain modest, expect further relative de-rating. If management accelerates buybacks materially, that is the fastest catalyst for the bear thesis to unwind.
• Avoid using BRK.B as a generic market hedge while the index is trending higher. Its current behavior suggests it is no longer a reliable outperformer in up-markets, but it still retains crisis convexity.
