Summary
Flash Boys exposes the world of high-frequency trading (HFT) and how it rigged the stock market against ordinary investors. Lewis follows Brad Katsuyama, a Canadian trader at RBC who discovered that HFT firms were using speed advantages — measured in microseconds — to front-run orders and skim billions from the market. The book reveals how exchanges sold co-location services and special order types that gave HFT firms unfair advantages, and how dark pools that were supposed to protect investors were actually designed to exploit them. Katsuyama's response was to build IEX, a new stock exchange designed to level the playing field by introducing a speed bump that neutralized HFT advantages. Lewis weaves together the technical details of network latency and order routing with a compelling narrative about a small group of idealists taking on the entrenched power of Wall Street.
Key takeaways
- High-frequency traders exploited microsecond speed advantages to front-run ordinary investors
- Stock exchanges became complicit by selling speed advantages to HFT firms
- Dark pools that promised to protect investors were actually designed to exploit them
- IEX was created as a fair exchange with a built-in speed bump
- The stock market's complexity serves those who profit from it, not ordinary investors
