Stocks with a $1 trillion market value may seem invincible, but they aren't.
Many of these stocks have seen their earnings and valuations soar due to AI.
However, one of these stocks is very likely to outperform in a bear market.
Remarkably, there are now over 10 stocks in the S&P 500 index with market values exceeding $1 trillion. I don't know how many people could have predicted that at the turn of the century. Even more remarkable is the fact that several more aren't too far away from joining this elite group.
Now, many stocks in the $1 trillion club have benefited from the artificial intelligence (AI) boom. Some have high valuations, while others truly generate tremendous free cash flow and earnings.

At this size, one might think that all of these stocks are too big to fail. Some very well might be, but I believe several could be vulnerable to big sell-offs in a bear market, in which the market falls at least 20% from a recent peak, as investors take a risk-off approach to AI.
However, I believe one would outperform in a bear market. It's not remotely close, and the stock is actually on sale.
The clear quality name to own in a bear market is Berkshire Hathaway (NYSE: BRKA)(NYSE: BRKB), which has a market capitalization of just over $1 trillion. Berkshire is the large conglomerate that the great Warren Buffett and the late Charlie Munger built into an absolute juggernaut through many decades of disciplined investing focused on fundamentals and the power of compounding.
While I do believe many of the hyperscalers have built diversified tech businesses that will survive even if AI struggles, that doesn't mean their stocks won't take a hit, as they have all performed exceptionally well as beneficiaries of AI.
Berkshire doesn't focus on AI, but it has a number of business lines that are quite different from one another and have achieved a certain scale and moat that will be difficult for most competitors to replicate. Berkshire, the owner of GEICO, runs the third-largest property and casualty insurance company in the U.S. GEICO is also the second-largest private passenger auto insurance company in the U.S.
Berkshire also owns a significant number of large energy assets, a large mortgage business, and the Burlington Northern Santa Fe Railroad, the largest railway company in the U.S., among others.
While Berkshire isn't going to outgrow AI companies in a bull market, it will outperform them in a bear market because it owns durable businesses that span different and vital parts of the economy and can perform across various interest rate environments. These businesses can also implement AI across many aspects of their operations to improve efficiency.
The other great thing about Berkshire is that it earns tens of billions of dollars a year in profits, even after removing its tens of billions in investment gains. The investment gains come from Berkshire's nearly $330 billion equity portfolio, in which Buffett and his team have invested in stocks for decades across a variety of sectors. Buffett is widely considered one of the greatest investors of all time.
Finally, Berkshire has a fortress balance sheet. At the end of the first quarter of 2026, cash, equivalents, and short-term investments in U.S. Treasury bills approached nearly $400 billion. While some investors would like to see Berkshire put that money to work, it will be good to have it in any bear market, and also allow Berkshire to be aggressive if it sees opportunities in a down market.
Berkshire stock has struggled this year, down 4.5%, compared with the S&P 500's 10.5% gain. Part of this may be due to Buffett stepping down as CEO at the end of 2025.
Buffett chose the longtime Berkshire veteran Greg Abel as his successor. Abel is certainly capable, but no one can ever replace Buffett, who likely earned Berkshire a premium in the market. Still, for investors looking to add protection against a potential bear market, Berkshire stock is on sale.
One way to value Berkshire is on a price-to-tangible-book basis, which compares a company's market cap or stock price to its tangible book value (TBV), or TBV per share, which is essentially equity minus intangible assets and goodwill. Price-to-TBV is a common way to value financial stocks.
As of this writing, Berkshire traded at a price-to-TBV ratio of 1.68. Its five-year average is 1.86. If you are looking to add, now is as good a time as any.

Four leading AI models discuss this article
"Valuation risk for the trillion-dollar AI megacaps remains underappreciated, and BRK.B’s safety in a bear market depends on ongoing capital allocation quality and a believable path for the AI cycle."
Article pushes Berkshire as a bear-market hedge and crowns the AI megacaps as beneficiaries, but the bear-case is not trivial. A rate-risk regime or a deceleration in AI demand could compress multiples for the trillion-dollar club far more than traditional moats. Berkshire’s moat is real, but its cash pile near $400B by Q1 2026 raises opportunity-cost questions if rates stay high or if capital allocation under the Buffett/Abel transition falters. The piece glosses insurance-mathematic risks, Berkshire’s energy and railroad exposure, and regulatory risks facing tech giants. Missing: explicit earnings trajectories, ROIC, debt mix, and the timing/price of AI capex cycles.
Counterpoint: If AI spending remains buoyant and growth re-accelerates, these megacaps could re-rate further, making Berkshire’s ‘safety’ thesis less compelling; the bear-market outperformance argument hinges on an uncertain macro path and capital-allocation bets.
"Berkshire Hathaway's valuation discount is a reflection of the 'Buffett Premium' evaporating rather than a genuine opportunity to buy a defensive asset at a deep cyclical discount."
Berkshire Hathaway (BRK.B) is currently trading at a P/TBV of 1.68, notably below its five-year average of 1.86. While the 'safety' narrative holds water due to the $400 billion cash pile, investors are ignoring the 'Buffett Premium' decay. With Buffett stepping down, Berkshire effectively transitions from a capital-allocation machine led by a singular genius to a massive, diversified conglomerate that essentially tracks the broader economy. In a true bear market, the correlation between Berkshire’s rail, energy, and insurance segments and the S&P 500 is higher than the article suggests, meaning it may offer less 'uncorrelated' protection than investors anticipate.
If interest rates remain elevated, that $400 billion cash hoard generates significant risk-free yield that could actually boost Berkshire's book value faster than its operating segments during a recession.
"Berkshire is a legitimate bear-market defensive play, but a 9.7% valuation discount does not constitute 'on sale,' and the article's certainty about relative outperformance ignores recession risks to insurance and rail operations."
The article conflates two separate theses: (1) Berkshire as bear-market hedge, and (2) Berkshire as 'on sale.' The first has merit—diversified cash flows, $400B fortress balance sheet, and low correlation to AI do provide downside protection. But the valuation argument collapses under scrutiny. A 1.68x price-to-tangible-book versus 1.86x five-year average is a 9.7% discount—immaterial for a 'sale' narrative, especially given Buffett's succession uncertainty and the fact that Berkshire's $330B equity portfolio is itself vulnerable in a bear market. The article also ignores that Berkshire's insurance float and railroad assets face headwinds in recession. Calling this 'not remotely close' as the best $1T stock to own overstates the case.
If a bear market arrives, Berkshire's insurance underwriting spreads compress, railroad volumes collapse, and that $400B cash hoard becomes a liability (pressure to deploy or return capital). Meanwhile, mega-cap tech may stabilize faster than conglomerates historically do, especially if they cut costs aggressively.
"Berkshire's diversification offers no proven edge in bear markets once the Buffett premium is removed."
The article positions Berkshire Hathaway as the clear defensive pick among $1T+ S&P 500 names for a bear market due to its conglomerate structure, $400B cash pile, and 1.68x tangible book value discount to its five-year average. Yet the claim rests on untested assumptions about post-Buffett execution and the resilience of its insurance, rail, and energy segments. Historical drawdowns show BRK.B fell roughly in line with the S&P 500 during 2008-09; a recession-driven bear could expose correlated losses across its cyclical holdings rather than provide outperformance. The 4.5% YTD lag versus the S&P's 10.5% gain already prices in some succession discount.
A broad equity selloff triggered by higher rates or geopolitics could still punish Berkshire's equity portfolio and insurance float more than the article admits, while hyperscalers retain pricing power even in downturns.
"Berkshire’s TBV discount and cash hoard do not guarantee protection; in a recession, float pressure and cyclical assets may drive underperformance vs broad equities."
Claude, I’d push back on the '9.7% TBV discount is meaningful' line. In a recession, Berkshire’s insurance float profitability can compress, rail volumes dive, and the energy exposure adds cyclicality risk. The 1.68x TBV multiple doesn’t protect you if the equity portfolio—heavily tech-ish—falls with AI demand and the 'Buffett premium' fades under succession risk. In a true bear market, Berkshire may underperform broad equities despite cash heft.
"The decay of the 'Buffett Premium' post-succession is a more significant risk to Berkshire's valuation than current book value multiples or cash-hoard defensive narratives."
Gemini, your focus on the 'Buffett Premium' decay is the most critical overlooked factor. While others debate valuation multiples, they ignore that Berkshire’s current price reflects the market's faith in a singular capital allocator. As that transition completes, the conglomerate discount will likely widen, regardless of the cash pile. If the 'genius' premium evaporates, the stock doesn't just lose its defensive appeal; it faces a structural re-rating that could significantly lag the broader market during a downturn.
"Berkshire's defensive case hinges on insurance/rail resilience and cash deployment speed, not on whether its equity holdings fall with the market."
ChatGPT conflates two separate risks. Yes, Berkshire's equity portfolio is tech-heavy (~$330B), but that's a *portfolio* risk, not a Berkshire-specific one—any diversified holder faces it. The real bear-market test isn't whether BRK.B's equities fall; it's whether insurance underwriting spreads and railroad volumes collapse *faster* than the cash hoard can absorb losses. Gemini's 'Buffett Premium decay' is the structural risk, but it's orthogonal to recession protection. A bear market tests cash deployment speed, not just multiple compression.
"Berkshire's tech-heavy equity portfolio under post-Buffett management poses amplified allocation risks in a downturn beyond generic market exposure."
Claude underplays the equity portfolio's role. The $330B tech-leaning holdings aren't just generic diversified risk; under Abel without Buffett's oversight, any bear-market markdown could trigger questions about capital allocation agility that the cash pile alone won't resolve, especially if insurance and rail cash flows slow simultaneously.
The panel's net takeaway is that Berkshire Hathaway's defensive appeal in a bear market is overstated, with key risks including the potential evaporation of the 'Buffett Premium', the vulnerability of its tech-heavy equity portfolio, and the cyclicality of its energy and railroad holdings.
