Introduction
You face a constant risk of losing money in financial markets whenever a new technology promises to change the world. Greed and collective amnesia convince you that the current boom is fundamentally different, causing you to buy near the peak of speculative bubbles.
Alasdair G. M. Nairn argues in Engines that move markets that technological manias follow a repeating five-stage cycle. Insiders systematically profit while ordinary investors suffer from excessive optimism and subsequent crashes.
The book traces this pattern across two centuries of financial history, examining canals, railways, electricity, automobiles, computing, and the internet.
The following questions guide this exploration:
- How do technological manias develop through predictable stages?
- Why do infrastructure booms consistently end in financial crashes?
- Which strategies help you identify surviving market leaders?
1. Timeless Lessons and the Technology Cycle
Sir John Templeton noted that the four most expensive words in the English language are "This time it is different". Understanding past financial history prevents you from falling victim to this dangerous belief during speculative manias.
Studying past financial history and understanding the five-stage technology cycle protects you from speculative manias and the false belief that the current market cycle is fundamentally different.
Investors during technological booms frequently put savings into concept investing rather than sound businesses. Promoters exploit this appetite through aggressive stock promotion and superlative-laden claims in newspapers.
Frank Fayant investigated 150 companies that advertised in the Sunday New York Herald during 1901-1902. Five years later, only one was still paying dividends, and its stock traded at less than half of what investors paid. The New York Herald collected $175,000 in advertising income from speculative companies during that fourteen-month period, while Northern Pacific stock reached $1,000 a share during the peak speculation.
Technological advances follow a consistent lifecycle model through distinct phases:
- stage one: concept and feasibility;
- stage two: from feasibility to prototype;
- stage three: funding and commercial viability;
- stage four: rationalisation and refinancing;
- stage five: ultimate success and failure.
Financial market bubbles require specific macroeconomic conditions beyond mere technological novelty. Low interest rates, uncritical trade press promotion, and previous prosperity combine to inflate speculative excess, as seen in the 1840s railways, the 1900s, the 1920s radio boom, the 1960s electronics wave, and the 1990s TMT bubble.
2. Canals and the US Railroads
The early canal and railroad booms demonstrated how heavy infrastructure investments attract speculative manias, severe stock watering, and ruthless short squeezes before collapsing into consolidation.
Early transport relied heavily on turnpikes and canals. Many of these waterways struggled with maintenance costs, collection difficulties, and poor routing. Although successful waterways like the Erie Canal generated massive initial revenues, the subsequent canal boom led to inflated construction costs and terrible losses once railroads proved their economic superiority.
The Erie Canal cost roughly $7.5m to construct and earned annual tolls of $500,000 to $750,000. This success inspired a massive US canal boom before railroads ultimately captured the traffic and caused a steady secular decline in canal usage. Between 1816 and 1860, investors poured $200m into US canal construction. Up to 1850, investors put $372m into US railroads, followed by another $600m in the seven years to 1857.
Ruthless financiers utilized cornering operations, short squeezes, and corrupt political alliances to manipulate stock prices, weaponize legal injunctions, and ruin rival speculators. Operators like Vanderbilt and Jay Gould bought up available floating shares to execute classic short squeezes against bear raiders who had sold short expecting manipulated price drops. They also bribed local politicians and judges to issue favorable injunctions or legalize unauthorized stock issuances, creating severe liquidity crises.
When Daniel Drew and other bear raiders sold New York and Harlem Railroad stock short, Vanderbilt bought up the available float and executed a short squeeze. He forced them to repurchase shares at $179 and netted over $1m in profit, after organizing a fund pool of $5m to buy all offered Harlem stock during a bear raid.
The battle for control of the Erie Railroad symbolized the extreme stock watering, corruption, and insider plundering that characterized the robber baron era of American railroads. Daniel Drew, Jay Gould, and Jim Fisk repeatedly flooded the market with convertible bonds and stock to dilute Vanderbilt's holdings, siphon off cash, and fund their own operations. Protected by corrupt judges and armed guards in New Jersey, they extracted millions from the railroad while leaving its balance sheet in ruins and pushing it toward repeated bankruptcies.
During the Erie war, Drew, Fisk, and Gould fled to New Jersey with $7m in cash and company paperwork to evade arrest warrants issued by Judge Barnard under Vanderbilt's pressure. Gould ultimately issued $20m in total bonds and shares without corresponding capital expenditure or improvements, and imposed a $9m debt cost on Erie to reimburse Vanderbilt in their settlement agreement.
Subcontractors and insiders systematically siphoned wealth from the Union Pacific through massive overcharging and corrupt political patronage. The Credit Mobilier construction company overcharged Union Pacific between two and three times the real cost of construction, hiding millions in unaccounted funds. Stock in the company and inflated supply contracts, such as the Wyoming Coal and Mining Company, were used to enrich insiders and bribe politicians to protect corporate privileges.
Total construction costs reached $94 million against an estimated true cost of $44 million, leaving roughly $50 million unaccounted for until Oakes Ames testified before Congress in 1872.
Companies that rely on continuous equity issuance to fund dividend payouts or acquisitions operate like a house of cards. When economic slowdowns occur or interest rates rise, the arithmetic fails, debt mounts, and the entire edifice collapses into liquidation or restructuring.
The York and North Midland Railway funded its dividends and acquisitions through equity issuance for nearly ten years until the system collapsed when profitability fell and interest rates rose.
When you evaluate capital-intensive businesses during market manias, you must prioritize cash flow analysis over reported profits because profits can be easily misrepresented.
- Check the cash flow position when in doubt.
- Analyze cash balances and cash flows to find the true underlying position.
3. Telegraph and Telephone Networks
Western Union and AT&T built enduring monopolies through patents and consolidation, proving that incumbent monopolies can dismiss new communication technologies until forced to adapt.
Following the collapse of the unstable Treaty of the Six Nations pool, Western Union merged with competing networks. It benefited immensely from 14,000 miles of new lines inherited after the Civil War. By trading free telegraph access for railroad right-of-way and station space, Western Union annexed national infrastructure and marginalized competitors.
By 1878, Western Union operated 7,500 offices, employed 12,000 people, and controlled 200,000 miles of cable.
Alexander Graham Bell leveraged his background in speech acoustics and strong financial connections to develop and patent the telephone. Bell was born in 1847. He took on the tuition of George Sanders in 1872. Bell's patent was submitted to the US Patent Office on 12 February 1876.
Bell demonstrated his telephone at the Philadelphia Centennial. Emperor Dom Pedro II of Brazil tested it and Sir William Thomson listened to Hamlet's soliloquy over 100 yards.
Western Union tragically misjudged the commercial potential of the telephone. In 1876, the Bell consortium offered their patents to Western Union for $100,000, but Western Union president William Orton declined.
The sum paid for the first leased telephones in May 1877 was $20, while total notes signed by Sanders to bankroll the venture reached $110,000.
Despite possessing massive financial resources, Western Union viewed Alexander Graham Bell's telephone as an insignificant toy. Once the legal cases regarding telegraph patents were settled and the telephone gained adoption, the telegraph became a niche asset.
In 1910, the Bell company took control of Western Union. Bell later was forced to divest due to monopoly concerns, marking the end of the telegraph's supremacy.
Under J.P. Morgan's backing and Theodore Vail's leadership, AT&T pursued aggressive consolidation, cost-cutting, and eventual compromise with regulators. J.P. Morgan organised $130m in additional funding in 1907. AT&T reached a 75% net debt to equity ratio in 1907.
In 1909, AT&T acquired a 30% stake in Western Union to combine telegraph and telephone services before later relinquishing control under regulatory pressure.
4. Electric Light and Power Wars
Edison and Westinghouse waged fierce technical and marketing battles over lighting and current standards, showing that heavy infrastructure requires massive capital and patent pooling.
Initial enthusiasm for new lighting technologies can easily inflate speculative stock bubbles before commercial viability is proven. Charles Brush established the Anglo-American Brush Electric Light Corporation in 1880, raising over £9m raised in Britain by early 1882 to supply electric lighting. Investors rushed into regional subsidiary companies named after their geographic rights, driving up share prices despite arc lighting's inability to compete commercially with gas lighting.
Shares of the Anglo-American Brush Electric Light Corporation rose sevenfold over a short period, while Hammond Company shares more than quadrupled before the bubble burst in 1883.
Thomas Edison frequently announced major breakthroughs and predicted the end of gas lighting before technical hurdles were fully overcome. He used press interviews and staged demonstrations for financiers to keep the flow of capital active despite ongoing research difficulties.
Edison invited New York City Board of Aldermen to Menlo Park for a technical discourse that culminated in illuminated rooms and food from Delmonico's restaurant when boredom set in.
Edison championed direct current, which suffered from severe current leakage and required generation plants in close proximity to customers. George Westinghouse and Nikola Tesla championed alternating current, which allowed large central generators to supply distant areas efficiently using transformers.
Harold Brown and Thomas Edison enlisted a crusade against alternating current by electrocuting animals to demonstrate its dangers, which backfired when New York State bought Westinghouse AC dynamos for the death penalty.
Financial pressures, patent litigation, and the need for working capital forced competing electrical companies to merge. Under the financial aegis of J.P. Morgan, Edison General Electric and Thomson-Houston merged to form General Electric, while patent pools were established with Westinghouse.
In 1892, Edison General Electric merged with the Thomson-Houston Company to form General Electric with a capitalisation of $50m.
5. The Search for Oil and Standard Oil
Faced with high costs for coal oil and whale oil, investors funded a search for rock oil as a cheaper source of kerosene. Edwin Drake, an out-of-work railway conductor appointed with a fictitious military title, used salt-boring techniques and a steam engine in Titusville, Pennsylvania, to pump oil directly out of the ground on August 28, 1859. US oil production reached 0.5 million barrels annually by 1860.
John D. Rockefeller achieved total industry dominance in petroleum through vertical integration, secret railroad rebates, and aggressive depreciation strategies.
Recognizing that crude oil production was volatile and subject to the law of capture, Rockefeller concentrated on the marginally less volatile refining business. By guaranteeing full-capacity shipments to railroads, you can see how he secured steep discounts and drawbacks that crushed his competitors. Rockefeller partnered with Henry Flagler, built pipelines like the Allegheny Transportation Company, and negotiated a 75 percent discount on the Erie rail system and a 30 percent discount with Vanderbilt's New York Central System.
Standard Oil maintained absolute financial strength and self-financed expansion by utilizing massive cash reserves and aggressive depreciation charges. During the severe economic slump following the 1873 panic, Rockefeller approached struggling refiners in Pittsburgh and Philadelphia with irresistible buyout offers. To minimize public outcry and political scrutiny from antitrust regulators, Standard Oil charged excess depreciation of 6 to 10 percent of assets, deflating declared profits without affecting cash.
Following damning reports and local operating cases, the Supreme Court ordered the dissolution of Standard Oil in 1911 under the Sherman Antitrust Act. The trust was divided into geographic operating units within 6 months from 21 June 1911 given to complete the dissolution process. Standard Oil of New Jersey became Exxon, New York became Mobil, California became Chevron, Ohio became Sohio, and Indiana became Amoco. Standard Oil of California achieved 10 times higher net income in 1920 than in 1911.
6. The Rise of the Automobile
Early transport relied heavily on horses or railways. Inventors experimented with steam, gas, turpentine, and alcohol for self-powered carriages. Volume-versus-power constraints and fuel availability limited their utility.
The automobile triumphed over steam and electric propulsion through petrol-powered internal combustion, leading to massive early manufacturer mortality and Ford's low-cost volume dominance.
The petroleum-derived waste product gasoline ultimately provided the ideal lightweight, energy-dense fuel for internal combustion engines. Jean-Joseph Lenoir designed an early gas engine in France in 1860. William Morrison designed an electric car in Iowa in 1892.
The early automobile industry saw a three-way battle for propulsion between steam, electric, and gasoline engines. Steamers offered smooth running and no stalling. They required massive amounts of water and suffered from poor power-to-weight ratios. Electric cars were quiet and odourless but limited by heavy, short-range batteries. Gasoline engines initially faced skepticism. They continuously improved their technology, overcoming their rivals within a few years.
In 1900, steamers were actually the largest-selling type of automobile in America. Production reached 1,681 steamers, 1,575 electric automobiles, and 936 gasoline automobiles.
Henry Ford leveraged a first-mover advantage in low-cost, high-volume production. He built an insurmountable cost barrier and achieved extraordinary profitability. He focused on the most affordable segment of the market and introduced the Model T. Ford experienced self-reinforcing success. Massive production volume drove down unit costs. Ford maintained exceptional returns on assets without external equity or debt. Despite continuous price reductions, Ford Motor Company's return on assets exceeded 60% up to 1914. Sales and net income grew at annual compound rates exceeding 65%.
William Durant built General Motors through an uncurbed buying spree of automobile and component companies. He financed deals with securities and debt while ignoring central cost controls and cash management. Economic downturns hit inflated inventories and overgeared positions. Emergency financial bailouts by banking syndicates followed. By 1910, General Motors required an emergency cash injection of $15m to survive. A financial consortium dictated terms and removed Durant from leadership. Later, the Du Ponts and Morgans covered $30m of personal debts to bail out Durant in 1920.
7. Radio Broadcasting and Television
Pioneering inventors like Marconi and Sarnoff transformed wireless physics into commercial broadcasting funded by advertising and backed by government-backed patent pools.
Guglielmo Marconi transformed abstract academic physics into a practical commercial wireless system. He built upon the theoretical work of James Clerk Maxwell and Heinrich Hertz. He used practical trial-and-error methods rather than pure theory to transmit messages through the atmosphere without wires.
Marconi formed the Wireless Telegraph and Signal Company in 1897 with a capital of 100,000 pounds, equivalent to $37m. He received 15,000 pounds in cash, equivalent to $5.5m, and 60,000 pounds in paid-up shares, equivalent to $22m, for his patents.
Unscrupulous promoters leveraged public fascination with new technologies to build stock-jobbing schemes where corporate survival depended entirely on continuous share sales rather than operational revenues. Stock promoters utilized elaborate corporate shells, watered capital structures, and unverified press releases to inflate share prices.
Abraham White partnered with Lee de Forest to triple the capital of the American De Forest Wireless Telegraph Company to $15m while explicitly acknowledging that the business was sustained by share sales.
You can observe how promotional schemes follow a consistent pattern:
- Form a company with some apparent claim on radio technology and allocate shares among the promoters.
- Raise public awareness and draw attention to the company and its apparent prospects through publicity and demonstrations.
- Sell shares to the public at whatever share price can be generated, preferably rising in steps to maintain interest.
Strategic national interests and military needs often lead governments to intervene in emerging technology markets. Following World War I, the US government and Navy opposed British Marconi's dominance. The US Navy took over shore stations during World War I and later facilitated the creation of RCA, paying nearly $3m to remove British Marconi ownership.
David Sarnoff of RCA helped form NBC in 1926 by leasing AT&T telephone lines and purchasing the WEAF station for $1m as a flagship.
8. Mainframes and Personal Computers
Computing evolved from mechanical adding machines and centralized mainframes to commoditized personal computers driven by semiconductor advancements and software operating systems.
Charles Babbage designed the conceptual foundations of modern digital computers a century ahead of his time. He built the difference engine to mechanically calculate mathematical powers and print results. Later, he conceived the analytical engine, separating functions into a store, a mill, and pre-defined formulae controlled by punch cards.
Charles Babbage received an initial £1,500 from the British Treasury, ultimately spending over £30,000 of government and personal funds without producing a working final version of his difference engine.
Herman Hollerith revolutionized large-scale data processing by replacing manual census tallies with an electrically powered, punched-card tabulating system. For the 1890 US census, the Hollerith Electric Tabulating System helped reduce production costs by roughly a third and cut publication time down to two and a half years, nearly two-thirds faster than the 1880 census.
The invention of the transistor and the semiconductor chip triggered an economic antithesis to Grosch's law, summarized as Moore's law, driving lower costs and massive market expansion. Vacuum tubes were limited by heat, size, and power consumption. The invention of the solid-state transistor at Bell Labs in 1947 allowed electronic circuits to shrink drastically. Robert Noyce and Gordon Moore left Fairchild Semiconductor to found Intel in 1968, developing the 4004 microprocessor containing 2,000 transistors.
Ed Roberts of MITS created the first commercially successful personal computer, the Altair, by combining a discounted advanced Intel chip with a marketing partnership. Faced with liquidation from the calculator price collapse, MITS secured an 80% discount on Intel 8080 chips. Popular Electronics agreed to feature the machine, retailing the unassembled Altair computer for $397.
IBM entered the personal computer market in 1980, legitimizing the industry and establishing the cloning paradigm by outsourcing key components and software. Compaq built an equivalent PC from scratch without copying IBM's technology, garnering sales in excess of $100m in its very first year.
Microsoft secured long-term dominance in the software industry by winning the IBM operating system contract and retaining the right to license its software to third parties. Bill Gates acquired and adapted SCP-DOS into MS-DOS within six months, positioning Microsoft to control the industry standard as clones proliferated.
9. The Internet Boom and Survivors
The late 1990s Internet bubble combined easy money and promotional hype to drive speculative excesses, out of such wreckage resilient survivors like Amazon, Google, and Facebook emerged.
Tim Berners-Lee invented the World Wide Web at CERN by creating a non-hierarchical, hypertext-based system operating on top of standard internet protocols. He wrote Enquire and later developed the hypertext transfer protocol (HTTP), universal resource identifiers (URI), and hypertext markup language (HTML) to let computers share information across the Web. Using a NeXT computer provided by Steve Jobs, Berners-Lee built a program for building, browsing, and editing hypertext pages, ultimately making access to the Web protocol free after negotiations with CERN in 1994.
A prototype version of the Web server was up and running by Christmas 1990. Selling products on the internet is most effective when targeting fragmented production markets with unified international cataloging and centralized distribution. Jeff Bezos researched optimal products for e-commerce and selected books because publishing and retail sales were fragmented, a global cataloging system already existed, and the product was standardized regardless of vendor. Bezos left D. E. Shaw and established Amazon in Washington state to minimize sales tax while positioning near a major book distributor.
Prior to Amazon, the maximum combined market share for any two booksellers in the US was 25 percent. Amazon raised $1m by the end of 1995 at an implied valuation of $5m, followed by an $8m capital injection from an $8m beauty parade valuation of $60m. Amazon prioritized aggressive scale, fulfillment infrastructure, and minimizing inventory over immediate profits, utilizing incoming customer revenues before paying suppliers to survive severe balance sheet pressure.
Lehman Brothers analyst Ravi Suria issued a bearish report dubbed Amazon.toast in 2000, missing the underlying cash flow generation power of high-growth rapid turnover businesses. Amazon accumulated $0.5bn in operational losses when shareholder equity was less than half that figure, yet later achieved 25 percent per annum compounding sales revenue growth post-2001 and surpassed $100bn in annual sales for the first time by 2015.
Search engine accuracy can be radically improved by treating web page links like academic journal citations, weighting volume by quality. Sergey Brin and Larry Page developed PageRank at Stanford University, initially naming their search engine Google after googol, the mathematical term for 1 followed by 100 zeroes.
The late 1990s TMT bubble combined cheap money, free access to a new communications channel, and investor exuberance to create a classic stock market bubble driven by immediate trading gains rather than business fundamentals. Investment banks fed public demand with an endless supply of IPOs during the 1997 to 2003 Web 1.0 timeframe. Institutions and retail investors chased immediate risk-free profits on day-one trading spikes, utilizing the greater fool theory. Analysts and promoters abandoned traditional profitability metrics, shifting their focus upward to revenues, website hits, eyeballs, and stickiness. Merrill Lynch technology analyst Henry Blodget gave Excite the second-highest rating to investors while describing it in private emails as such a piece of crap, leading to a $4m SEC fine and a permanent industry ban.
Leading market indices experienced a fall of 50 percent or more between 2000 and 2003 when the bubble burst. Despite the severe crash, companies like Google, Amazon, and Facebook built real operational success through sales and profit growth. By the end of 2016, the combined market capitalization of just Google, Facebook, and Amazon surpassed 50 percent of the top 100 UK listed companies and roughly 20 percent of the Dow Jones Industrial Average.
