How it works
What a mirror is, how the prediction model is built and tested walk-forward, and why this is a research publication.
method · honesty · disclaimer
Prior Moves is a research publication, not investment advice. Predictions are model probabilities about future 13F filings; the backtested edge is small and not statistically significant. Prior Moves is a research publication: one impersonal model portfolio per investor, identical for every reader. You place any trades yourself at your own broker. No execution, no custody, no individualised advice. Full disclaimer.
