“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.”

“Monemetrics would invest a bit of money for Simons, testing strategies in a variety of markets. If the tactics looked profitable, Simons would place the same trades in Limroy, which was much bigger and would invest for outsiders as well as for Simons. Baum would share in the 25 percent cut the firm claimed from all its trading profits.”
