Berkshire Hathaway's performance, although exceptional, does not refute the universal impact of size on sustained alpha.
Their model, involving full company acquisitions like BNSF, represents a different strategy from traditional investment funds facing liquidity constraints.
This example illustrates a capacity to control capital deployment that is not replicable for most asset managers.
The market noise around this unique case should not obscure the structural challenges posed by large capital volumes.

But what impact will these equity acquisitions have on job stability or the economic fabric of the targeted companies? It is not enough to consider the source of funding; the real question is who benefits and who pays the price, especially when it involves small and medium-sized enterprises that could be vulnerable to such consolidations. Let us not forget that Berkshire's cash flows, although vast, often come from diversified sectors, which can mask local vulnerabilities.

Stating that the insurance float is only a contingent liability lacks nuance, as it ignores the true competitive advantage of skillful management.
The ability to transform this obligation into a low-cost investment capital source is what separates the high performers from others.
Insurers that dominate the Singapore market know that it is not the float itself, but how it is arbitrated that determines victory.
A poorly managed float, as shown by some regional players during past crises, does not allow you to lap your competitors; it simply causes you to lose money.

Insurance float is not an unavoidable liability but a strategic leverage that top players use to dominate the market. Those who see it only as a contingent debt miss the opportunity for arbitrage and fall behind. The most successful insurers, like those operating in Singapore, turn this constraint into opportunity, generating returns even under underwriting pressure. It is a race to optimize capital, not a binary opposition between asset and liability; the ability to do so is the mark of alpha in the market.

Residual alpha of 0.1% for Berkshire is certainly a statistical curiosity, but historically, such residual alpha claims for entities of this scale should be approached with healthy skepticism. The market playbook has long taught us that the ability to generate significant alpha diminishes as assets under management increase, because large-scale investment opportunities are rare. Considering this small figure as decisive evidence against size restrictions ignores precedents where sovereign funds managing hundreds of billions struggle to outperform their indices after fees. An alpha of this magnitude could easily be drowned in methodological noise or market fluctuations, as seen with the ephemeral quants' alphas in the 90s, which evaporated over time.

L'idée que la taille de la capitalisation boursière de Berkshire Hathaway "diminue inévitablement ses avantages informationnels et limite sa flexibilité" est une simplification qui ignore le véritable motif derrière ces affirmations.
Ceux qui propagent cette narrative, souvent des maisons de courtage ou des fonds plus petits, ont un conflit d'intérêts clair en tentant de justifier leur propre absence d'alpha ou leur incapacité à opérer à cette échelle.
Pour une entité de cette envergure, comme Berkshire, la question n'est pas la simple taille, mais la stratégie de déploiement de capital et les incitations du management, par exemple, leur discipline à détenir des réserves stratégiques de liquidités plutôt que de les déployer hâtivement, comme le montre leur bilan.

The assertion that the float of insurance is a low-cost capital neglects the quantification of maintenance costs which can reach a significant ratio.
Consider that a combined ratio of 105% for an insurer already implies an implicit cost of 5% before any investment return.
This contingent liability is far from being perpetual without impeccable management and substantial liquidity reserves, which increases the risk ratio.
Events like the pandemic or natural disasters quickly turn this capital at charge into a liability, requiring prudent allocation and reducing margin of return.
Operating this float requires an active risk management to maintain a positive viability score, and not just simple exploitation to generate alpha.

It is true that the size of a fund can, at first glance, seem to limit options and pressure returns, but this is an incomplete story that ignores the chapters where governance and strategic vision rewrite the destiny of these funds.
It is not the raw size of capital that inevitably dictates the compression of returns, but rather the story we choose to live.
When a fund like ours, the KIA, invests in critical infrastructure or long-term partnerships, the question is not only about immediate returns but about stability and impact on future generations.
It is a story of power and vision, not just numbers on a spreadsheet; for example, our investments do not always seek the fastest gain, but a diversification that anchors our economic future in sustainable relationships.

The idea that the "friction" of capital deployment is merely a compression of returns fails to grasp the true dynamics at play. The role of a sovereign wealth fund is to shape the economic scene, not just react to existing market tensions. We do not passively endure the market as a constraint, but actively shape it to create new opportunities and new investment narrative arcs. For example, our fund can finance large-scale green energy initiatives, not only for financial returns but also to establish an entire economic sector that did not exist before our intervention. This story is one of action, not mere reaction.

The assertion that the insurance float is mainly a contingent liability ignores the reality of the actors who use it as a powerful competitive advantage.
Market leaders, such as Berkshire Hathaway, beat the competition by transforming these funds into productive capital, even with long-term obligations, which allows them to win the race for alpha.
It is the ability to manage risk with discipline and to allocate capital intelligently that makes the difference, not the simple nature of the float as a liability, as demonstrated by the consistent performance of dominant insurers who know how to turn reserves into strategic levers.

Isn't it unwise to consider insurance float as a perpetual and low-cost investment fund, when it is actually a conditional obligation? Ignoring the capitalization requirements of MAS in Singapore means losing the race for regulatory advantage. Reserves for future claims are not optional; they are key to maintaining credibility and avoiding penalties. A company that does not manage its reserves aggressively will quickly fall behind others. For example, if an insurance company does not allocate enough capital to cover catastrophe risks, it risks being subjected to investment restrictions or substantial fines, limiting its ability to generate alpha.

The '65%' verdict of an AI debate in 2026 offers no empirical basis to judge Berkshire Hathaway's past performance; it is speculation, not a factual analysis.
Interpreting the 2015 performance should focus on the actual market conditions of that year, such as the interest rates of the Bank of Canada or commodity prices, which influenced the capital allocation strategy.
Claiming that a future AI model can dictate our understanding of past financial events limits our ability to achieve optimal performance by not distinguishing between rigorous retrospective analysis and projection.
For example, relying on this obscure futuristic verdict obscures why Berkshire's high cash reserves in 2015 might have been a strategic decision for opportunistic capital deployment, rather than a simple obstacle.
To maximize understanding, we must demand tangible proof of the performance drivers of the time, not a post-factum validation by AI.

Labeling the float as insurance as merely a 'contingent liability' grossly underestimates its role as a competitive advantage for actors who know how to exploit it.
It is a race for capital where agile management of these funds before claims can generate significant alpha.
Leading companies do not see it as a simple future obligation but as an immediate opportunity to deploy these resources in high-yield markets.
Failing to recognize this potential leaves a crucial advantage on the table and loses the race.
