  • Navinder Sarao and the 2010 Flash Crash: Stub Quotes and Spoofing

    Got something to say to this podcast? Send a voicemail, and you might hear yourself on the next episode!

    We expect a trillion dollar disaster to have a trillion dollar villain. The Flash Crash of May 6, 2010 had Navinder Singh Sarao, a point and click trader in a messy childhood bedroom in Hounslow. This episode follows the mechanics closely. High frequency firms had spent billions on straight line fiber and co-located servers to win a race measured in microseconds. Sarao could not win that race from London, so he hired a programmer to rework his software and hacked the traffic lights instead, acting like a phantom bidder at an auction who slips out before the hammer falls.

    The episode gives special attention to why blue chip shares sold for a single cent. Market makers obliged to post prices had entered stub quotes, absurd placeholders that worked like an out to lunch sign, and a Kansas mutual fund's algorithm kept selling until those were the only bids left. Nobody's code glitched. That idea anchors the closing discussion of the synthetic outlaw, a system that works as designed and still does prohibited harm, and what it means as artificial intelligence takes over power grids and logistics.

    • Sarao's fake orders in E-mini S&P 500 futures totaled roughly 200 million dollars, landing just as Waddell and Reed began a real 4.1 billion dollar sale.
    • Early theories blamed a fat finger error at Procter and Gamble and glitches at the New York Stock Exchange before a whistleblower's data analysis led to Sarao.
    • At his April 2015 arrest he faced 22 counts, was held on 50,000 pounds bail, and was said to have more than 25 million pounds in Swiss accounts.
    • His lawyers later told the court the fortune was nearly wiped out by bad investments and fraudsters pitching wind farms and guaranteed returns.
    • He received one year of home confinement in 2020, and the crash led to explicit bans on spoofing and layering plus market wide circuit breakers.

  • Navinder Singh Sarao: The Bedroom Trader Blamed for the Flash Crash

    On May 6, 2010, the Dow fell nearly a thousand points and a trillion dollars in market value disappeared in 36 minutes. Five years later, authorities pointed to Navinder Singh Sarao, a 36 year old trading in sweatpants from his parents' stucco house in West London. This episode explains how he got there: Regulation NMS linked the exchanges, high frequency firms exploited the milliseconds between them, and Sarao learned to fool their algorithms with huge sell orders he never meant to fill.

    The story also asks whether he was a culprit or a scapegoat. That afternoon a mutual fund identified as Waddell and Reed was selling 4.1 billion dollars of E-mini contracts into a market already rattled by fears of a Greek default, and the high frequency machines shut themselves off like robot vacuums at the top of a staircase. Then comes the twist: the man who outwitted supercomputers handed his fortune to con men selling fake wind farms, and walked away with no prison time.

    • Sarao's modified off the shelf software placed about 200 million dollars in fake sell orders and changed them 19,000 times before canceling.
    • With liquidity gone, Accenture and Procter and Gamble briefly traded at a penny a share while Apple and Sotheby's spiked above 100,000 dollars.
    • Academics blamed order flow toxicity, arguing the market was already poisoned an hour before the crash.
    • Arrested in April 2015 on 22 criminal counts, Sarao was said to have made more than 40 million dollars between 2009 and 2015. By 2017 his lawyers reported the money was gone.
    • In January 2020 a judge sentenced him to one year of home confinement, citing his cooperation, his Asperger's diagnosis, and the absence of ordinary greed.

  • Inside the Boiler Room: Pump and Dumps, Sucker Lists and Ruined Lives

    Got something to say to this podcast? Send a voicemail, and you might hear yourself on the next episode!

    A boiler room is an outbound call center built to push questionable investments through dishonest, high pressure sales. The name is literal: operators once set up folding tables in the cheapest basements they could rent and packed in brokers who were punished for straying from the script. This episode takes the scam apart like a magic trick, showing how three verifiable facts soften a target for the fourth, fabricated one, and how a house stock secretly owned by insiders is pumped with victims' money and then dumped until the bids vanish.

    The model proved hard to kill. It moved from the Bond Daddies of Memphis and Little Rock, who sold inflated municipal bonds to cautious savers, to New York crime families in the 1990s, then onto cheap internet phone lines that let a room in Barcelona or Valencia target victims in the United Kingdom. On Australia's Gold Coast, operators sold bogus betting software behind dormant shelf companies. Against the glamour of The Wolf of Wall Street, the episode sets the real cost: depression, broken marriages, and suicide.

    • The assembly line has three tiers: qualifiers who cold call in volume, verifiers who close a small first sale, and senior brokers who drain everything that is left.
    • When the calls stop, the firm that was the only market maker disappears, leaving victims with shares that cannot be sold at any price.
    • By 2012 the Australian Crime Commission called the Gold Coast the country's capital of investment fraud, with losses estimated at 113 million dollars or more.
    • Scammers buy shelf companies registered a decade or more earlier so that a victim checking the public registry finds a long, clean record.
    • Sucker lists, traded databases of people already defrauded, let operators target those most desperate to win back what they lost.

  • John D. Rockefeller: How the Standard Oil Breakup Made Him Richer

    Got something to say to this podcast? Send a voicemail, and you might hear yourself on the next episode!

    In 1911 the Supreme Court ordered Standard Oil broken into 39 companies, a punishment meant to end the most notorious monopoly in American history. Instead it doubled John D. Rockefeller's fortune and left him the wealthiest person on earth. This episode traces how that happened, beginning in the chaotic oil boom of Ohio and Pennsylvania, where Rockefeller ignored the gamble of drilling and focused on refining and transport, the toll booth every barrel had to pass through.

    The turning point came in 1868, when he promised the Lake Shore Railroad 60 carloads of oil a day and won a rate of one cent per gallon, a 71 percent discount that rivals could never match. From there the story moves through the conquest of Cleveland, the secret South Improvement Company and its drawbacks, the 1882 Standard Oil Trust run by nine trustees, and the reporting of Ida Tarbell that turned the public against him. It closes on a hard question: do antitrust laws dismantle power or only rearrange it?

    • Rockefeller's 1868 railroad deal guaranteed 60 carloads a day and handled all loading himself, cutting his shipping costs 71 percent below competitors.
    • Between 1865 and 1870 the price of refined kerosene fell from 58 cents a gallon to 26 cents, which made him popular with ordinary consumers even as independent oilmen despised him.
    • Under the South Improvement Company scheme of 1872, Standard Oil would have collected drawbacks, cash payments on the oil its own competitors shipped. In less than two months he absorbed or destroyed nearly all his Cleveland rivals.
    • The Standard Oil Trust of January 1882 pooled the securities of 40 companies under nine trustees to slip past state ownership laws, and was valued at 70 million dollars at its creation.
    • After the 1911 breakup Rockefeller held a quarter of the shares in each of the 39 new companies, and once the fear of government action lifted, their combined value doubled.

  • Robber Barons: How a Medieval Insult Came to Define the Gilded Age

    Got something to say to this podcast? Send a voicemail, and you might hear yourself on the next episode!

    In 1975 Stanford students voted to name their sports teams the Robber Barons. The administration vetoed the choice as disrespectful to founder Leland Stanford, a railroad magnate and one of the very men the phrase was made famous to describe. The term itself is far older. It comes from the German Raubritter, feudal lords who built castles above the Rhine and charged illegal tolls on passing merchants, taking wealth at a choke point without creating any.

    This episode follows the phrase from the Rhine to American politics. It first landed on Cornelius Vanderbilt in 1859, then spread to Andrew Carnegie, J.P. Morgan, Jay Gould, and John D. Rockefeller. Historians have fought over it ever since. Matthew Josephson's 1934 book cast the tycoons as a threat to democracy, while Allan Nevins answered in 1940 that men like Rockefeller brought order to industrial chaos. The same argument now surrounds Jeff Bezos, Elon Musk, Bill Gates, and Mark Zuckerberg.

    • On February 9, 1859, the New York Times applied the idea to Vanderbilt after subsidized shipping rivals paid him to keep his cheaper steamships off their routes.
    • The word baron stung in a republic founded on rejecting aristocracy, and cartoonists drew businessmen in crowns and royal robes.
    • Historian John Tipple described a devil view of history, in which people battered by depressions blamed visible villains instead of hard to grasp economic forces.
    • Railroads run by men like Leland Stanford were drawn as an octopus, its tentacles wrapped around state houses, farms, and small businesses.
    • Burton W. Folsom Jr. separates political entrepreneurs, who live on subsidies and government favor, from market entrepreneurs who win by cutting costs. By that test Vanderbilt belongs in the second group.

  • Levi Strauss: The Peddler Who Never Invented Blue Jeans

    Got something to say to this podcast? Send a voicemail, and you might hear yourself on the next episode!

    The name on your jeans belongs to a man who did not invent them. Levi Strauss was born Loeb Strauss in Buttenheim, Bavaria, in February 1829, and came to New York at 18 with his mother and two sisters. His brothers Jonas and Louis ran a wholesale dry goods business on Liberty Street, and he began as a peddler, carrying kettles, blankets, and sewing supplies door to door. It was hard labor, and it taught him what working people wanted most from the things they bought: that they last.

    This episode follows him to San Francisco, where he arrived in March 1854 after crossing Panama and opened Levi Strauss and Co. as a wholesale importer. While prospectors gambled on gold, he sold them clothing, bedding, tents, combs, and handkerchiefs. Then a customer changed everything. Jacob W. Davis, a tailor in Reno, Nevada, had found a way to stop work pants from tearing, and he needed a partner with money and reach to patent it.

    • Davis reinforced pocket corners and the base of the button fly with copper rivets in 1871, so the metal took the strain instead of the thread.
    • He wrote to Strauss in 1872 asking for help with the patent. It was issued in 1873, with one half assigned to Levi Strauss and Co.
    • Strauss never married. When he died in San Francisco in September 1902 at 73, his estate of roughly $30 million passed to his nephews, whose descendants still own the company.
    • He helped establish Congregation Emanu-El, the first synagogue in San Francisco, funded orphan charities, and in 1897 endowed 28 scholarships at the University of California, Berkeley.
    • A 1960 episode of Death Valley Days called The Million Dollar Pants gave him an invented romance and replaced Jacob Davis with a fictional character named Patrick Mahoney.

  • Black Friday 1869: How Jay Gould and Jim Fisk Cornered the Gold Market

    Got something to say to this podcast? Send a voicemail, and you might hear yourself on the next episode!

    In 1869 the public supply of gold in New York was only about $15 to $20 million, while the country ran on paper greenbacks that could not be exchanged for it. Railroad baron Jay Gould saw that a man with enough money could buy the whole supply and set the price. Only one thing stood in the way: the Treasury held roughly $100 million in gold, and Secretary George S. Boutwell was selling a few million every month. To corner the market, Gould had to get President Ulysses S. Grant to stop.

    This episode traces the scheme from its first bribes to its collapse. Gould and his flamboyant partner Jim Fisk worked through Abel Corbin, the president's brother in law, bought an informant inside the Treasury, and pitched Grant on the idea that expensive gold would help Western farmers export wheat and corn. When Grant paused the sales, they bought contracts worth three times the city's supply. On Friday, September 24, 1869, the president struck back, and the panic that followed reached far beyond Wall Street.

    • Gould paid assistant treasurer Daniel Butterfield $10,000, more than his $8,000 annual salary, to warn him the moment a government gold sale was ordered.
    • Grant's secretary Horace Porter refused a half million dollar gold account, Julia Grant turned down an interest in bonds, and Grant sent back $60,000 worth of art and statues.
    • The plot unraveled when a panicked letter from Corbin reached Grant during a game of croquet, and Grant had his wife write back demanding Corbin get out.
    • Knowing the end was near, Gould quietly sold his gold while Fisk kept buying. The Treasury then released $4 million and the price fell from 160 to 133 within minutes.
    • The stock market dropped 20 percent and wheat and corn lost nearly half their value. A congressional inquiry led by James A. Garfield cleared Grant, and neither Gould nor Fisk was ever convicted.

  • Jack Tramiel: The Commodore Founder Who Bought Atari for Revenge

    Jack Tramiel started in a Bronx typewriter repair shop in the early 1950s and ended up selling the best selling computer of the 1980s. Along the way his company, Commodore, was nearly destroyed twice by people it depended on: first when its financier Atlantic Acceptance collapsed in a fraud scandal in 1965, then when Texas Instruments began selling finished calculators for less than it charged Commodore for the chips inside them. Tramiel drew one lesson from both: own everything, trust no one.

    This episode follows how that lesson shaped the home computer market. In 1976 Commodore bought the chip maker MOS Technology, and with it engineer Chuck Peddle and his 6502 processor. The PET, the VIC-20, and the Commodore 64 followed, sold in Kmart like appliances and priced to bleed rivals dry. Then, at the height of the company's success in January 1984, Tramiel resigned after a clash with chairman Irving Gould, bought Atari's consumer division, and turned on the empire he had built.

    • To survive the Atlantic Acceptance collapse, Tramiel took a bridge loan against his German plant and gave Irving Gould nearly 18 percent of the company for half a million dollars in 1966.
    • The VIC-20, promoted in television ads by William Shatner, became the first computer to sell over a million units.
    • Because Commodore made its own chips, Tramiel could cut the Commodore 64 to under $200 in the 1983 price war, and Texas Instruments left the home computer market.
    • After Commodore sued him over trade secrets, his team found an old development contract between Atari and Amiga and countersued to block Commodore from using the Amiga technology it had just bought.
    • The Atari ST, nicknamed the Jackintosh, fought the Amiga through the 16 bit era. Commodore went bankrupt and was liquidated in 1994.

  • The Gold Standard: Isaac Newton's Math Error That Ruled World Money

    Got something to say to this podcast? Send a voicemail, and you might hear yourself on the next episode!

    The gold standard is remembered as the model of financial discipline, yet no one designed it. In 1717 Isaac Newton, master of the Royal Mint, fixed one gold guinea at 21 silver shillings. The ratio overvalued gold compared with mainland Europe, so merchants brought gold into Britain, bought silver cheaply, and shipped it abroad for profit. Silver drained out of the country, and Britain ended up on gold by accident.

    This episode explains how that accident became a global rule and why the world gave it up. It covers the centuries when silver did the daily work of commerce, France's role as the balancing weight of a two metal system, and the Franco-Prussian War indemnity that let Germany launch the gold mark. It then turns to the Great Depression, when defending gold reserves meant raising interest rates into a banking panic, and to Bretton Woods and its end in 1971.

    • In 15th century England a skilled artisan earned about six pence a day, while one small gold ducat was worth 40 pence, far too much for everyday purchases.
    • After defeating France, Germany extracted an indemnity of five billion gold francs, more than 1,400 metric tons of gold, and used it between 1871 and 1873 to replace regional silver currencies.
    • In Lubeck in 1877 authorities found 20 mark gold coins being shaved just enough to pass public weight checks, one reason central banks moved gold into vaults and issued convertible paper.
    • Britain suspended gold in 1931, and the United States followed in 1933 and 1934, when Franklin D. Roosevelt devalued the dollar by over 40 percent against gold.
    • Bretton Woods pegged the dollar at $35 per ounce in 1944 until Richard Nixon suspended convertibility in 1971. In a 2012 survey, 92 percent of economists said a return to gold would not improve price stability or employment.

  • William Chaloner: The Counterfeiter Isaac Newton Sent to the Gallows

    Isaac Newton's most dangerous opponent was not a rival mathematician. He was William Chaloner, born around 1650 to a poor weaver in Warwickshire and apprenticed to a nail maker in Birmingham, a town notorious for forged groats. Chaloner walked to London in the 1680s, found the guilds closed to him, and worked his way up through the underworld: selling tin watches with hidden sex toys, posing as a quack doctor, and playing a psychic who recovered goods he had stolen himself.

    This episode follows his climb from street hustles to a counterfeiting operation that bought him a mansion in Knightsbridge, and then to his boldest scheme, persuading the Privy Council that the Royal Mint was corrupt and that he should help run it. He forged Bank of England notes, betrayed his partners to the hangman, and collected rewards for it. Then Newton, as warden of the Mint, built a case too wide for Chaloner to talk his way out of.

    • Clipping had stripped English silver coins of nearly half their weight, and smugglers were melting good coins to sell as bullion abroad.
    • Chaloner split his operation among a goldsmith, an engraver, his brother in law, and separate distributors, and moved the noisy presses to a house in Egham, Surrey, beyond the reach of London magistrates.
    • When the Bank of England issued 100 pound notes on marbled paper in 1695, he got the same paper from its printer. Once caught, he turned informer and received a 200 pound reward.
    • Associates Aubrey Price and Matthew Coppinger were both hanged after Chaloner turned them in.
    • At the Old Bailey in March 1699 Newton produced eight witnesses, among them wives and widows of men Chaloner had betrayed. He was convicted of high treason and hanged at Tyburn on March 22, 1699.
