Market Regimes
How can market phases be described as state, transition, and uncertainty without turning them into false certainty?
The research index connects each published method, public evidence record, and dataset to the operational system it supports. Agenda entries are research questions—not product announcements.
The current library contains the published method, the continuously updated public evidence record, and its machine-readable dataset.
Research question, model logic, evaluation boundary, intended use, and known limitations.
Open →The continuously updated, publicly delayed record with complete and open subsequent windows.
Open →Machine-readable SPY prices, regime score, and HIGH observations using one consistent cutoff.
Open →Only Market Regimes currently produces an operational system. Other programs describe the direction of inquiry and carry no release commitment.
How can market phases be described as state, transition, and uncertainty without turning them into false certainty?
Which observable conditions distinguish ordinary volatility from deteriorating liquidity?
How can model decay, instability, and regime dependence be measured after release?
Which interfaces help people use probabilistic evidence without turning it into certainty?
Performance-like numbers are published with a denominator, data cutoff, scope, comparison window, and nearby limitation. A system output is not presented as a personal recommendation.
The question comes before the output and states what the work does—and does not—attempt to answer.
Universe, cadence, cutoff, and training versus out-of-sample periods remain distinguishable.
Negative, early, incomplete, and contradictory observations stay part of the interpretation.
Overlapping windows, non-stationarity, missing inputs, and excluded costs are stated where relevant.
Published work links to the system it informs, while paid access never removes the delayed public scrutiny layer.
