Practical Examples

1. Brad Katsuyama discovers market manipulation.

   Katsuyama, working at the Royal Bank of Canada, notices that his stock orders are consistently front-run by faster traders. He realizes that these traders use speed advantages to profit at the expense of regular investors, prompting him to investigate the underlying causes.

2. Creation of IEX Exchange.

   To combat unfairness, Katsuyama and his team build the Investors Exchange (IEX), an honest stock exchange designed to neutralize the speed advantage of high-frequency traders by introducing a 'speed bump.' This innovation aims to level the playing field for all participants.

3. Hiding cable purchases for fairness.

   Haim Bodek, a whistleblower, reveals how some firms secretly purchase faster data cables between Chicago and New Jersey to gain milliseconds of speed advantage. Lewis details how these hidden practices allow privileged traders to anticipate market movements before others.

4. Dark pools and hidden trades.

   The book explores 'dark pools,' private exchanges where trades are hidden from the public, making it impossible for most investors to see the true price of securities. Lewis illustrates how these mechanisms are exploited by high-frequency traders for profit at the expense of transparency.

5. Interviews with industry insiders.

   Lewis includes interviews with computer programmers, bankers, and traders who have deep knowledge of market structure. These firsthand accounts reveal how ordinary people often become complicit in complex systems of manipulation, usually without understanding the full ethical consequences.

6. The race for speed.

   Lewis describes the extreme lengths traders go to improve their competitive edge, from laying specialized fiber-optic cables to tweaking algorithms. The constant arms race creates a market environment where technological speed trumps traditional investing skills.

7. Lobbying against IEX.

   As IEX tries to launch, entrenched financial interests lobby regulatory bodies and spread misinformation to protect their own profit models. Lewis details the political and economic challenges faced by innovators who try to bring transparency and fairness to the market.

8. Programming the market.

   The book features stories of programmers who design complex algorithms to exploit price movements in microseconds. Lewis highlights how these individuals shape market behavior, sometimes with little regard for the impact on ordinary investors.
