That's the question behind Nous Ergon: Alpha Engine (νοῦς ἔργον — "intelligence at work"), a fully autonomous trading system I've been building that combines AI-driven research, quantitative prediction, and rule-based execution. Quantitative finance — using mathematical models and statistical analysis to make investment decisions — has traditionally been the domain of institutional hedge funds with massive engineering teams. Large language models and modern machine learning tooling are changing that equation.
