A lie repeated often enough can masquerade as truth. Today, perhaps no lie is more pervasive than the invincibility of passive index funds. Heralded as the antidote to the shortcomings of active management, passive investing has transformed from a strategy into an ideology — unquestioned, unchallenged, and increasingly dominant. But like all myths, it obscures deeper, uncomfortable truths.
The allure of passive investing lies in its promise of simplicity and fairness, underpinned by the notion that markets are efficient and unbeatable. Yet beneath this facade lies a hidden bias — a statistical mechanism that systematically rewards size and momentum rather than intrinsic value or economic merit. Market-capitalization-weighted indexes look impartial, but they tilt the playing field. Money flows to companies that are already big and pricey, reinforcing a "rich-get-richer" cycle.
This structural bias creates a troubling concentration of capital in a handful of mega-cap stocks, embedding systemic risk into the financial system. Under the guise of diversification and stability, passive investing quietly amplifies vulnerabilities, inflating asset bubbles and exacerbating market volatility. Investors are sold a narrative of security, unaware that they are participating in a dangerous feedback loop where today's market winners, regardless of their underlying fundamentals, receive ever-larger allocations simply by virtue of their size and popularity.
Meanwhile, active managers find themselves in an existential crisis. Unable to stem the exodus of assets, facing relentlessly falling fees, they resort increasingly to questionable governance practices in desperation. Their struggle is mischaracterized as incompetence rather than what it truly is: an inevitable consequence of competing against a flawed benchmark. The tragedy is that the greatest victims of this systemic distortion are the very investors passive strategies claim to protect.
This book is fundamentally a story about a stalemate: on one side stands the powerful myth of passive investing, an entrenched and seemingly invincible juggernaut sold as an efficient solution. On the other is the active asset manager — capable and driven, yet helplessly trapped by the limitations of traditional investment thinking. These managers understand intuitively that something is wrong but remain unsure how to challenge the entrenched passive narrative effectively.
A significant contributor to this stalemate is one's collective poor knowledge of history. This gap is not merely a challenge for the masses but can persist for generations, even among the brightest minds, Nobel laureates included. The ability to ask questions — especially discomforting ones — is thus a central message of this book. Why has the myth of invincible indexing lasted so long? Because few asked the blunt question: is the failure in human skill, or in a deeper systemic flaw?
My father's quiet conviction — that science belongs to everyone — became the undercurrent of my life's work. I spent years cultivating both the discipline to learn and the audacity to question. After developing a scientific solution to the illusion of market invincibility, I found that the harder battle was not in the discovery itself, but in confronting the orthodoxy. It took me another decade to challenge the entrenched belief that benchmarks are beyond defeat. Speaking against consensus was not just a professional risk — it was a personal reckoning with doubt, legacy, and the courage to stand alone.
The goal is to empower asset managers and investors — no vague promises, no empty formulas. Instead, one dives into the statistics behind passive investing, exposing how it works, why it seems to win, and which hidden biases prop it up. By tracing the historical journey — from Archimedes' early insights to the flawed methodologies inherited from Étienne Laspeyres and the myths that arose around the S&P 500 — the book demystifies the hidden mechanisms driving the perceived success of passive investing.
This book is both an alarm bell and a call to action — a plea to abandon complacency and embrace clarity. It challenges one to question entrenched assumptions, to move beyond passive's broken paradigm, and to pioneer a more adaptive, transparent, and genuinely intelligent approach to investing. It is not merely about outperforming benchmarks but redefining them.
There was once a courageous grandmother in her nineties who took on one of the world's biggest financial institutions — and her two grandsons, who were also her money managers at the storied bank — when she discovered that her resources were being drained without her permission. Beverley Schottenstein fought for her rights in court, ultimately winning $19 million against J.P. Morgan Securities. Many called it an impossible victory. Her story is being turned into a limited series, and it resonates not just because she exposed wrongdoing, but because it highlights the ordinary person's struggle to protect their assets in a system that can feel rigged from every angle.
From one vantage point, her story is a clash between an individual and active managers who, under the banner of expertise, often end up taking high fees, making subpar decisions, or neglecting the very people they are supposed to serve. From another angle, it is about the growing popularity of passive investing, frequently presented as the safer, more transparent alternative. In reality, what looks like a clear line between so-called passive and active approaches can become blurred, leaving many investors unsure of where to turn.
When people speak of investing these days, they typically think of buying into index funds — a strategy often lauded for matching the market's performance without the burden of high fees or frequent trading. Index funds manage around 40 percent of all global equity investments, valued at roughly $50 trillion, in this way. Most of one's pensions, retirement funds, and personal nest eggs are parked in these indexes, on the assumption that if one just leaves them alone, they will steadily grow over time. It is commonly seen as a set-it-and-forget-it tactic — a way to maintain peace of mind while compounding returns over the years.
For a while, this approach appeared nearly flawless. Yet when one delves beneath the surface, one discovers that one's financial markets are more vulnerable than most people realize. The capital market infrastructure is built upon centuries of evolution — from the Osaka rice markets of the 1800s to today's digital platforms that interconnect global exchanges 24 hours a day. In theory, these networks allow for smooth price discovery, reducing the risk that one party fails to fulfill a trade obligation. It should be a model of fairness and stability, but in practice, the sheer scale of passive investing has begun to warp this price-discovery process.
When billions of dollars flow into index funds every month, often regardless of underlying economic signals, distortions can accumulate. Prices soar for market darlings while smaller or less popular companies can find themselves starved of capital — even if their fundamentals are strong. The entire market structure can become susceptible to shock, particularly when a large cohort of investors decides to exit at once. Regulators typically respond to financial crises after the fact, implementing rules and restrictions once the damage is done. They seldom intervene in advance — either due to legal constraints, fear of market interference, or simple inertia in the face of changing strategies.
This book raises that alarm. It presents research and facts, and substantiates its claim, exploring how passive investing, in its current form, might be playing a dangerous game of musical chairs. When the music stops, those who are unprepared risk losing a lifetime's worth of savings. At the same time, crises inevitably open new opportunities. Savvy, well-informed investors can position themselves not just to survive but to capitalize on the market's restructuring.
The fault lines in one's financial system have been building for years. Traditional active management, with its high fees and disappointing outcomes, has left the door wide open for passive strategies to explode in popularity. Many investors end up rushing to a cure that, over the long term, might prove more dangerous than the disease. This is not an invitation to panic, but rather a call to look beneath the surface. Beverley stands as an emblem of what happens when an ordinary investor sees what is at stake and chooses to act.
Beverley's lawsuit grabbed headlines in the 21st century, but its real roots stretch back centuries — starting, of all places, in the bustling port city of Syracuse in 275 BCE. Situated on the island of Sicily, Syracuse served as a conduit for distant peoples and ideas: caravans from Carthage brought exotic spices, while galleys from Athens and Corinth carried both goods and the philosophical debates of Plato and Aristotle. Overlapping cultures mingled in its forums, amphitheaters, and public baths, fostering a place where commerce, scholarship, and political ambition intersected at every turn.
Archimedes thrived in that cultural crossroads. His machines could hoist ships, yet he was just as absorbed by pure geometry — proofs that, to him, revealed nature's secrets. He devoured the works of earlier minds, from Egyptian surveyors to Greek mathematicians, carefully studying their ways of measuring land, distances, and angles. For him, the act of measurement — the process of comparing the known to the unknown — was the key to unlocking nature's hidden truths.
Yet, if there was one moment when Archimedes' passion for measurement crystallized into a method that would echo through the ages, it came in the form of a royal commission. The city's ruler, often called the tyrant king, had ordered the crafting of a splendid golden crown, meant to symbolize Syracuse's wealth and devotion to the gods. Rumors soon reached the king's ear that the goldsmith might have cheated him, substituting some portion of the gold with cheaper silver. Outraged at the thought of being deceived, the king demanded proof — yet insisted that the crown remain unharmed, its elaborate filigree and craftsmanship left intact. The challenge fell to Archimedes.
For days, Archimedes paced the city's marble colonnades, scanning the horizon of his own knowledge. He considered the geometry of cones, the properties of triangles, and the earlier theories on density he had discussed in his correspondence with distant scholars. Nothing felt precise enough to quieten his nagging doubts — until his moment of revelation in the public bath. As he lowered himself into the warm water, he noticed the waterline rise, displacing an amount of water precisely equal to the volume of his body. Suddenly, the need for an objective, unambiguous measure became clearer than ever.
If a known mass of pure gold displaced a certain volume of water, then any difference in the volume displaced by the crown would indicate adulteration. It was a pure and direct approach, free from the whim of subjective judgment. The delighted cry of "Eureka!" that supposedly rang through the bathhouse symbolized the triumph of method over guesswork.
By submerging the crown and a lump of pure gold in water and measuring the difference in displacement, Archimedes established a baseline — a crucial concept akin to what future generations would recognize as an index. The crown displaced more water than the pure gold sample; it was less dense, exposing the presence of cheaper metal. This step-by-step procedure transcended human opinion; it relied only on a natural phenomenon and precise observation, making the result unambiguous and unassailable. In many ways, this was the first grand demonstration of measurement as a universal language, one that could settle disputes irrespective of politics or personality.
Although it would be centuries before scholars formalized the concept of an index as one will understand it — a systematic reference point that simplifies comparisons over time or across different entities — the seeds of indexing were undeniably sown in that bathhouse moment. He showed that a trustworthy measurement must have a fixed, unshakable standard. Whether one is testing a crown, gauging price movements, or mapping an entire market, it is impossible to see the truth without a benchmark that is immune to human manipulation.
Much of Europe struggled to maintain any semblance of monetary stability in the centuries following Archimedes' legendary test. By the mid-1600s, mints scattered across the continent were rarely the pristine, orderly institutions one might imagine today. Each mint operated under a swirl of political whim, local commerce needs, and often the personal ambitions of a monarch seeking to stretch his treasury further than his resources allowed.
In England during the reign of Charles II, workers sweated over furnaces, melting gold and silver into molten metal that was poured, hammered, and pressed into thin blanks, then stamped with the monarch's portrait. In principle, a coin's face declared a set weight of gold or silver. But few outside the mint's inner circle knew how meticulously — or how carelessly — the ratio was enforced. Charles II, eager to fund foreign wars, saw an opportunity in this secrecy. By subtly increasing the proportion of base metals, he could mint more coins with the same amount of precious metal. At a glance, a coin appeared legitimate; its real value gradually diminished, hurting soldiers, merchants, and commoners alike.
It was in this environment that Rice Vaughan grew to question the true worth of these royal tokens. An observer by temperament and a writer by trade, he saw a quiet form of royal manipulation. He noticed that every passing year seemed to bring higher prices for bread, meat, and basic goods, and that wages no longer bought as much as they once had. Few in power drew the line between debased coinage and the creeping expense of everyday life. But Vaughan saw it clearly.
His book, A Discourse of Coin and Coinage, published in 1675, was not merely a condemnation of the king's practices but a deeper study of what one might call the "value of money." By compiling records of wages, commodity prices, and the compositions of coins minted over different periods, he created a rudimentary index — albeit not in so many words — that traced just how far currency had strayed from its original standard. Much like Archimedes, Vaughan relied on the idea of a benchmark to make sense of an unseen problem: the known quantity of precious metal in older, more honest coins, compared to the newer, debased issues.
During the decades following investigations into coinage, England found itself in a state of restless intellectual ferment. Sometime during this period, a young Oxford scholar confided in a respected preacher that he risked losing his fellowship if his outside income surpassed the fixed sum of five pounds — an archaic rule dating back almost three centuries. Enter William Fleetwood, Bishop of St. Asaph, who resolved to prove mathematically what many suspected anecdotally: that the real value of five pounds in 1440 had changed drastically by 1706.
Fleetwood did not simply guess at the "worth" of money. He documented the prices of staple goods — bread, wine, meat — across several centuries, compiling his findings into Chronicon Preciosum. Published in 1707, the text effectively became the first modern treatise on index numbers, laying out a comparative framework for measuring purchasing power and bridging temporal gaps that had left many observers confused about historical price shifts.
Yet if Fleetwood's insights marked a milestone, there was still an unclaimed opportunity. Adam Smith, writing in The Wealth of Nations in 1776, acknowledged Fleetwood's data and recognized that the value of money shifted over time. But he did not go further to embrace indexing as a core framework. Instead, he focused on grander notions like the division of labor, free markets, and the invisible hand, leaving the specifics of measuring price changes over time as a peripheral concern — a gap that would be probed by critics and, centuries later, by psychologists who questioned the efficiency of economics as a discipline.
Faint but vital signals of indexing were also arising elsewhere in Europe. Hardly anyone used the word "economist" yet; men who studied wealth and prices were often tax officials, financial clerks, or savants quietly compiling statistics. It was within these parallel currents that Nicolas Dutot and Gian Rinaldo Carli emerged, each wrestling with the mystery of how to measure what was happening to money, prices, and everyday life.
Born in Normandy, Dutot served as a clerk piecing together financial data for government officials. In 1738, his observations coalesced into a pivotal innovation that would later bear his name: the "Dutot price index." His solution was disarmingly straightforward — he took an arithmetic average of prices in one period and compared it to an arithmetic average of prices in a base period, producing a ratio that suggested how much "the price level" had shifted. He grasped that without a consistent method to compare one snapshot in time to another, all talk of rising or falling costs amounted to anecdote rather than evidence.
Not long after, Gian Rinaldo Carli, an aristocrat of notable curiosity in northern Italy, was alarmed by the frequent debasement of Italian coins and the resulting confusion over ballooning prices. He devised what came to be called the "Carli index," computing unweighted averages of prices. Where Dutot anchored the conversation in a ratio of averages, Carli dove into questions of coinage debasement just as Rice Vaughan had in 1675, arguing that the run-up in prices since the 15th century was in large part attributable to the declining precious-metal content in coinage. Together, Dutot and Carli introduced a crucial principle: to measure changes in prices over time, one had to collect data systematically and compare it to a consistent baseline.
By the close of the 18th century, the tapestry of Europe had been woven with the threads of the Enlightenment, revolution, and the earliest stirrings of industrial might. In this shifting context, two figures — Joseph Lowe and George Evelyn — stepped forward to solve a pressing problem: How could one create a single measure of prices that, unlike the unweighted approaches of Carli and Dutot, recognized that not all goods and services carried the same weight in people's lives?
It is often said that Evelyn coined or popularized the term "tabular standard," while Lowe refined the concept and argued for its application in real-world policies. Where earlier pioneers had focused on compiling averages, Evelyn and Lowe recognized a crucial failing: if bread accounted for half a working family's expenses while wine was a rare luxury, should these items still be counted equally in an index? They said no. It made sense to assign more weight to common necessities and less to luxuries — to do otherwise risked distorting the very reality that an index was meant to reveal.
Lowe made a case for applying his "tabular standard" to all corners of financial life — bonds, wage contracts, even land rents. If government bonds were repaid according to a scale that rose or fell with a weighted price index, neither debtor nor creditor would be unfairly penalized by inflation or deflation. Their combined legacy resonated: they brought forth the key advancement that indexing needed to evolve from a clever observational tool into a possible cornerstone of economic policy — the recognition that, by weighting goods differently, one could arrive at a far more realistic measure of how the cost of living changed.
By acknowledging that bread is more vital than brandy, or that housing costs typically matter more than silk scarves, Lowe and Evelyn bridged the gap between the older, unweighted models and the fully developed indexing systems that major governments and institutions rely on today. And so, in the early 19th century, the science of indexing entered a new phase, poised to become more rigorous, more influential, and better equipped to capture the reality of life in a rapidly modernizing world.
