(Bloomberg) — Before Flash Boys came along; before the 60 Minutes crew turned up; before, in short, all of Wall Street knew his name, Brad Katsuyama championed a controversial idea: the U.S. stock market is rigged.
Today, after outmaneuvering some of the oldest, richest and most powerful names in the business, Katsuyama and his upstart company, IEX Group Inc., finally got what they wanted: designation as a full-fledged stock exchange.
The news, announced by the Securities and Exchange Commission, puts the hero of Flash Boys, the best-seller by Michael Lewis, on equal footing with the 224-year-old New York Stock Exchange and a host of newer all-electronic venues that, to some, have allowed high-speed traders to profit at everyone elses expense. The establishment has countered that IEXs unconventional model to slow things down poses dangers of their own.
For the moment, Katsuyama, 38, can breathe easy. Fridays news followed months of a public, and often nasty, battle over whether to let IEX — which only started trading in 2013 — join the ranks of the nations official exchanges.
We are grateful and humbled by the support weve received from the investor community, Katsuyama said in an e-mailed statement. Without it, we may have faced a different result. This is a milestone for all of those who have supported IEX and we look forward to becoming a stock exchange, which will provide us the opportunity to have an even greater impact on the markets.
The stakes are high. When IEXs Investors Exchange goes live in August, it will get the chance to prove itself and deliver on its lofty promises: to gain market share by fundamentally changing the way the $23 trillion U.S. stock market operates and tilt the odds back in favor of investors. Katsuyama contends investors are being victimized by the proliferation of high-frequency traders, or HFT, that engage in predatory strategies.
While IEX handles less than 2 percent of U.S. equity trading in its dark pool, that could increase because, with exchange status, brokers would have to route orders its way when it has the best price.
Any new exchange is a welcomed addition to us in terms of just there being another option to consider, Bill McNabb, chief executive officer of mutual-fund giantVanguard Group, said this week at a Morningstar Inc. conference in Chicago. He declined to comment on IEX specifically. Youve got all the algorithmic traders and hedge funds trying to figure out and get in front of what big institutional players are doing.
To the naysayers, however, IEXs quirky model threatens to distort prices and inspire copycats, creating a hall of mirrors that needlessly adds to the complexity of a stock market already fragmented across 12 exchanges and dozens of private trading venues. That said, the SEC said Friday that any other exchanges that want to deploy a speed bump cant expect to get a rubber stamp — approval will be evaluated on a case-by-case basis.
At the center of all the controversy is IEXs 350-microsecond speed bump, a coil of fiber-optic cable that all orders must pass through to reach its systems. While thats an imperceptible amount of time for humans, IEX says its just enough to blunt the light-speed trading strategies that have undermined investor confidence. Big money managers, including Bill Ackmans Pershing Square and David Einhorns Greenlight Capital, have supported IEXs ambitions, providing seed money for the venture.
Its campaign to gain exchange status has spurred intense criticism from the likes of Citadel Securities, which handles 15 percent of all equity trades in the U.S. and is owned by billionaire founder Ken Griffins Citadel LLC, as well as NYSE and Nasdaq. They argue that IEXs model risks undermining one of the bedrock tenets of modern market structure. The 2005 rule, known as Regulation NMS, requires that investors get the best available price when they buy or sell shares. IEXs opponents argue that its strategy of delaying orders will result in stale prices, putting it in conflict with the regulation.
The SECs approval would also set a dangerous precedent, they say, byintroducing more fragmentation and encouragingsimilar exchanges to open afterward. That would lead to multiple venues showing obsolete price quotes. It would then be almost impossible for brokers to get the best price for their clients, and could even provide new opportunities for gaming the system.
Our markets work extraordinarily well for retail and institutional investors, and we need to be vigilant in identifying any unintended consequences of the approval, Jamil Nazarali, head of execution services at Citadel Securities, said in an interview.
Stacey Cunningham, chief operating officer of NYSE Group Inc., said the exchange objected to IEXs proposal because they were looking for exemptions to existing rules. She spoke in an interview before the SECs decision was announced.
Katsuyama rose to prominence with the 2014 publication of Lewiss Flash Boys, which argued that HFT, banks and exchanges had conspired to rig the U.S. stock market. Shortly after the book was published, Katsuyama sparred with then-president of exchange operator Bats Global Markets Inc., William OBrien, on CNBC, in an argument that captivated Wall Street.
During the debate, OBrien pressed Katsuyama on the books claim that markets are tilted in favor of the fastest traders.
Its a yes or no question, OBrien said. Do you believe it or not?
I believe the markets are rigged, Katsuyama responded.
After Flash Boys was published, Katsuyama took up meditating. He strives for 15 minutes a day, using a headset that senses brainwaves and gives real-time feedback, as a break from the attention and controversy swirling around his company. A lot of this game is mental, he said during an interview this year.
Along the way, IEX has gained a number of enemies as it challenged the status quo. An ugly war of words played out as IEX progressed through the exchange approval process, with Jeff Sprecher, the CEO of Intercontinental Exchange Inc., calling the firms approach unfair and un-American in a post-earnings call with investors.
The gestalt of the design, the Michael Lewis book and IEXs marketing — all of those things together have made it a referendum on an industry, more than a 350-microsecond speed bump on its own might warrant, said Eric Budish, an economics professor at the University of Chicagos Booth School of Business.
And calls to reject IEXs application for exchange status continued, even after the firm compromised on a separate part of its design earlier this year and changed the way it routes unfilled orders to other venues.
The SECs approval may prove to be just a temporary respite. Last month, Nasdaq warned regulators that a lawsuit challenging IEXs approval would likely succeed.
That means Katsuyama will have precious little time to savor his biggest victory.
