“Scientists and mathematicians are trained to dig below the surface of the chaotic, natural world to search for unexpected simplicity, structure, and even beauty.”
― Gregory Zuckerman, The Man Who Solved the Market: How Jim Simons Launched the Quant Revolution

“The strategies were often based on the idea that prices tend to revert after an initial move higher or lower. Laufer would buy futures contracts if they opened at unusually low prices compared with their previous closing price, and sell if prices began the day much higher than their previous close. Simons made his own improvements to the evolving system, while insisting that the team work together and share credit.”

“Elsewhere, statisticians were using similar approaches—called kernel methods—to analyze patterns in data sets. Back on Long Island, Henry Laufer was working on similar machine-learning tactics in his own research and was set to share it with Simons and others. Carmona wasn’t aware of this work. He was simply proposing using sophisticated algorithms to give Ax and Straus the framework to identify patterns in current prices that seemed similar to those in the past.”

“Whatever work a man may be doing, it is enough for him to try to do each action deliberately, with his mind, following every movement, and he will see that the quality of his work will change immediately.”
