Fundamentals
The working definitions and core methods behind micro-alpha research, so you can reason about weak signals on solid ground.
4 articles · a guided path
Micro alphas are small, often short-lived predictive signals that carry little edge on their own and only become useful in combination. This pillar sets the shared vocabulary and first-principles methods the rest of the site assumes: what a micro alpha actually is, how signal research is structured, how a candidate signal is validated against noise, and how its contribution is attributed once it is live.
The articles are meant to be read as a progression. Start with what a micro alpha is and where systematic strategies look for one, then move to how signal discovery is organized as a research process. From there, statistical validation covers how to decide whether a weak signal is real or an artifact of the search, and attribution closes the loop by separating a signal's genuine contribution from overlap with factors you already hold.
Read together, these pieces are the toolkit you reach for before touching portfolio construction, execution, or machine-learning methods. They are deliberately method-first and stack-agnostic: the goal is to make your downstream choices defensible, not to prescribe a single workflow.
What you’ll learn
- →Define what a micro alpha is and where systematic strategies search for one
- →Structure signal discovery as a repeatable research process rather than ad hoc hunting
- →Apply statistical validation to separate a genuine weak signal from search artifacts
- →Attribute a live signal's contribution and isolate it from factors you already hold
- →Build the shared vocabulary the portfolio, execution, and ML pillars assume
