The Flash Crash of 2010 [1:30]
On May 6, 2010, the stock market experienced an unprecedented event known as the flash crash. The day began with market volatility due to concerns about the European debt crisis, as indicated by a 22.5% increase in the VIX, or fear index. At 2:32 p.m. ET, a massive block of 75,000 e-mini S&P 500 futures contracts, valued at $4.1 billion, was suddenly dumped onto the market, triggering a rapid and chaotic plunge. Within minutes, the market dropped nearly 10%, and individual stocks experienced irrational price swings. For example, Accenture's stock fell from $40 to 1 cent in seconds, while Apple's stock briefly surged to $100,000 per share. By 3:00 p.m., the market had largely recovered, but the 36-minute crash raised significant questions about its causes and the individuals responsible.
Who is Navinder Sarao? [4:14]
Navinder Sarao, born in 1978, began his trading career at Futex Live in the mid-2000s, where he excelled in trading futures contracts, particularly e-mini S&P 500 futures. By 2008, he had accumulated $2 million. He made a significant profit by betting on a stock market rebound during the global financial crisis, turning his $2 million into $15 million. However, he found it increasingly difficult to profit in 2009 due to the rise of high-frequency trading (HFT).
High-Frequency Trading and Spoofing [5:39]
High-frequency trading (HFT) involves powerful algorithms that execute millions of trades per second, scanning markets and exploiting loopholes. One strategy involves "flash orders," where some traders receive order information milliseconds before others, allowing them to profit from tiny price differences. Another strategy, highlighted in a New York Times article, involves market manipulation through "spoofing," where traders create and quickly cancel orders to trick others into thinking there is more interest in a stock than there actually is. Sarao, frustrated with HFT, began using spoofing to create fake orders and profit from the resulting price movements.
Navinder Sarao and the Flash Crash [9:06]
On May 6, 2010, Sarao used his spoofing and layering strategy to profit from the increased market volatility. By 2:40 p.m. ET, he had made $950,000 and logged off just before the flash crash began. While his fake trades accounted for 20% of all sell orders of e-mini S&P futures at times, pushing prices artificially, he was not actively trading when the crash occurred. An official report later found that a mutual fund's trading activity was the primary cause of the crash.
The Mutual Fund's Role [10:37]
The flash crash was primarily triggered by a mutual fund that initiated an order to sell 75,000 e-mini S&P futures contracts, valued at $4.1 billion, at 2:32 p.m. The fund used a sell algorithm set to execute 9% of the previous minute's trading volume without any price or timing limits. This algorithm failed because it relied on trading volume as an indicator of market liquidity, which was inflated by high-frequency traders. These traders increased trading volume without actually adding to the pool of willing buyers. As a result, the algorithm rapidly sold the contracts, overwhelming the market and causing the crash.
Aftermath and Consequences [14:29]
Following the flash crash, the Commodity Futures Trading Commission (CFTC) investigated Sarao's trading activity and passed the case to the Department of Justice (DOJ). In 2015, Sarao was arrested in the UK and indicted on 22 counts of wire fraud, commodities fraud, and manipulation. He admitted to making $12.8 million from illegal activities and entered a plea agreement in 2016, receiving one year of house arrest due to his cooperation. The flash crash led to the passage of the Dodd-Frank Wall Street Act, which defined spoofing as illegal and addressed flaws in financial markets.
