Brokers face increasing risks from technology errors
New york: Regulations put in place to protect investors after $862 billion (Dh3.1 trillion) of market value was briefly erased on May 6, 2010, were the same rules that almost ruined Knight Capital Group Inc. this month.
Knight, whose market-making unit executes 10 per cent of US equity volume, lost $440 million (Dh1.62 trillion) on August 1 and its stock has plunged 73 per cent after a computer malfunction bombarded the market with unintended orders that exchanges declined to cancel. A decade ago, the firm suffered almost no consequences in a similar breakdown when officials agreed to void trades after Knight mistakenly sold one million of its own shares.
The refusal to let Jersey City, New Jersey-based Knight out this time shows that brokers face increasing risks from technology errors after regulators toughened rules following the so-called flash crash two years ago. Knight, which unintentionally bought and sold exchange-traded funds and New York Stock Exchange companies, was forced into a rescue that ceded most of the firm to six investors led by Jefferies Group Inc.
“This is really a wake-up call,” David Whitcomb, founder of Automated Trading Desk LLC, a Knight rival bought by Citigroup Inc. for $680 million in 2007, said in a telephone interview. “They made one obviously terrible mistake in bringing online a new program that they evidently didn’t test properly and that evidently blew up in their face.”
Erroneous trades
Knight has been upended by computer errors before. On June 2, 2002, three days after Thomas Joyce started work as chief executive officer and president, its stock tumbled more than 50 per cent intraday when a software flaw caused its computers to spew out orders to sell the company’s shares. The Nasdaq Stock Market and Cincinnati Stock Exchange cancelled the transactions and Knight later pared the loss to 7 per cent.
The May 2010 flash crash inaugurated reforms aimed at reducing the discretion exchanges have to cancel trades. The Dow Jones Industrial Average tumbled almost 1,000 points in 20 minutes that day before rebounding after the automated sale of stock futures helped trigger waves of selling, according to a report by the Securities and Exchange Commission and Commodity Futures Trading Commission on September 30, 2010.
Rules formalising the treatment of erroneous trades were adopted amid criticism by investors after exchanges and the Financial Industry Regulatory Authority voided transactions totalling 5.6 million shares on May 6, 2010. Regulators added guidelines governing when sales or purchases of stock could be canceled after market makers said confusion about which trades would stand prevented them from acting during the rout.
Sudden surges
The rules had their biggest effect earlier this month after Knight’s errant orders caused volume suddenly to surge and prices to swing in dozens of securities just after trading began. Executives at the New York Stock Exchange cancelled transactions that were 30 per cent or more away from their price at the start of trading, a decision that applied to six securities out of 140 that were reviewed.
Unwanted transactions occurred in ETFs listed on NYSE Arca and in companies on the Big Board, Knight said in a regulatory filing on August 9. It previously hadn’t said its mishap affected ETFs. An update to software made in preparation for an NYSE program to lure more individual investors to the Big Board caused the mistaken orders starting at 9:30 a.m. New York time.
‘New application’
“It was a new application,” Joyce, now chairman and CEO, said in a phone interview with Bloomberg News on August 6. “It was certainly a technology issue that had been engineered to allow us to better interact with the retail liquidity program at the New York Stock Exchange, and it was obviously a greatly flawed application.” Joyce asked the SEC to give NYSE more flexibility to cancel trades because they were “one big error,” he said.
Even as Knight suffered, the changes prevented its problems from injuring market participants, Matthew Andresen, co-CEO of quantitative trading firm Headlands Technologies Inc., said.
“The market handled it well,” Andresen, a former Citadel LLC executive, said in a phone interview. “The harmonisation of the clearly erroneous policy worked very well and the plumbing worked very well. Unfortunately for Knight, they ended up making a $440 million donation to the marketplace.”
Joyce said the error that led to Knight’s loss was an “infrastructure problem” in an interview with Bloomberg Television on August 2.
“A software problem could have made the firm not aware of their own positions,” according to Hessler, who said in a phone interview he had no first-hand knowledge of Knight’s situation. “But good programming discipline also means there should be last-ditch backstop mechanisms to shut down trading when too many orders are going out or orders aren’t getting updated the way they should be.”
Knight appeared to repeatedly send orders “where they were buying at the offer and selling at the bid, and some were on stocks with wide bid-ask spreads,” Manoj Narang, CEO of Tradeworx Inc., a higher-frequency firm and technology provider based in Red Bank, New Jersey, said in a phone interview.
“It was a slow, painful, 15-cents-at-a-time death by small cuts, only it was happening every fraction of a second because computers are fast,” he said.
His automated trading firm experienced a similar mishap earlier this year in a broker’s dark pool, or private venue, he said. Firms supplying liquidity generally do so at the bid and offer prices. While Tradeworx’s issue occurred because of system changes the firm didn’t know about, the strategy was programmed to shut off after it lost $5,000, which took less than a minute, Narang said.
Stop loss
“What is confusing virtually everybody, including me, is why Knight didn’t have an automated stop loss in their strategies,” he said. “It was the first day of NYSE’s RLP program so there should have been multiple layers of risk controls. In addition to having automated stop losses there should have been humans watching the strategy like a hawk.”
NYSE Euronext was in touch with Knight “within minutes” after identifying the source of the errant trades on August 1, the exchange’s CEO, Duncan Niederauer, said on a conference call two days later. Knight participated in user testing associated with the start of NYSE’s retail liquidity programme, he said, calling the problem that befell the member firm a “routing error.”
Early in the call, exchange officials discussed whether the Knight trades could be treated individually instead of as a group event for determining when transactions could be cancelled and at what price, according to one of the people. The threshold for voiding trades in an incident involving 20 or more securities is 30 per cent.
Defining the errors as individual events may have spared Knight from greater losses because it means more trades are eligible for cancellation. In most cases, trades that occur 10 per cent or more away their previous price can be voided when the error involves a single security. Officials from NYSE Arca and Nasdaq argued against this, one of the people said.
Robert Madden, a spokesman for Nasdaq OMX Group Inc., and Richard Adamonis, a spokesman for NYSE Euronext, declined to comment. Joyce said on August 2 the mishap was Knight’s fault.
Outside adviser
Knight will hire an outside adviser to investigate what led to the losses, Kara Fitzsimmons, a spokeswoman, said on August 10. She declined to comment about what happened on August 1 beyond what the company already disclosed.
NYSE announced just before 3 p.m. it would cancel trades that occurred before 10:15 a.m. with price movements of at least 30 per cent from their opening levels. Niederauer and Mary Schapiro, the chairman of the SEC, said in separate comments on August 3 that the exchanges followed the thresholds laid out after the 2010 plunge.
“Technology people at trading firms are probably thinking, ‘There but for the grace of god go I,’” said James Angel, a professor at Georgetown University’s business school in Washington. “Every chief technology officer is thinking they don’t know what’s buried in some line of code or what unanticipated change will lead to failure. When unanticipated problems occur, operations people may face situations they’ve never seen before and don’t know what to do. It’s scary.”
