Three gauges. They rarely agree. The disagreement is the signal.
Every market morning, one short read of the entire Sentinel Stack — telling you which layer to believe today, and what its quarrel with the other two means. The Sibylline Brief, named for the oracle consulted in a crisis, reads probabilities, not certainties.
The Sentinel Analytics Stack measures the market on three independent axes — what the crowd is doing, whether the market's plumbing confirms the tape, and what the macro foundation looks like underneath. Each runs on its own clock: fast, medium, and slow.
On the rare days all three align, the read is easy. The valuable days are the other ones — when sentiment says one thing, internals say another, and the foundation says a third. That's when most people pick the gauge that confirms what they already believe.
The Sibylline Brief exists for exactly those days. It treats the divergence between the layers as the primary signal, names which one to weight today, and explains in plain language what their disagreement is telling you — in about two minutes, before the open.
Each gauge is a 0–10 composite. Read alone, any one can lie. Read together — and against each other — they triangulate.
The Bear-Bull Index reads what participants are actually doing — contrarian by design. Extremes matter more than direction; a calm reading is the absence of a warning, not an all-clear.
The Market Regime Indicator asks whether the market's internals confirm the headline tape. It tends to lead price — the plumbing breaks before the index does.
Trend-Risk-Macro is the structural layer beneath everything — the slow-moving foundation measured in quarters, not days. It sets the backdrop the other two play out against.
Not raw gauge readings — you have those. The judgment that connects them.
One clear line on which layer carries the most information today — and whether the three are aligned, mildly split, or in open conflict.
The interpretation that's hard to do yourself: when the crowd, the plumbing, and the foundation disagree, what is that specific disagreement actually signalling?
The observable market states that would resolve the divergence one way or the other — described as conditions, never as instructions to act.
Written like a desk's morning note — tight, plain, and finished before your coffee is. No dashboards to interpret, no noise.
An illustrative excerpt. The live brief is generated each morning off the current stack.
| Layer | Reading | Says |
|---|---|---|
| BBI | Neutral, drifting up | No extreme to fade — not an all-clear |
| MRI | Slipping, leads price | Internals diverging from the index |
| TRM | Benign, slow | Foundation still a tailwind |
The read. Two of three gauges are constructive, which is exactly why the third deserves the weight today. The plumbing leads, and it has begun to diverge from a tape that still looks orderly on the surface — the configuration where the headline index is the last to know.
The condition that would dissolve the divergence: internals re-confirming the tape into the close. The condition that would deepen it…
Layered on top of the $49/mo Analytics Stack membership — the daily synthesis that turns three gauges into one decision.
No. The Sibylline Brief is a daily synthesis of the Sentinel Analytics Stack that describes market conditions and what the gauges' divergence signals. It does not forecast outcomes or recommend any action, and the conditions it names are written as observable market states, never as instructions. It's general, impersonal commentary — not personalized advice.
The Brief is the premium tier of the Sentinel Analytics Stack, and the $99/mo includes full Stack access — you get the live BBI, MRI, and TRM gauges plus the daily synthesis that reads across them. It's the interpretation layer on top of the instruments.
Because a single gauge is easy to over-trust, and on most days at least one of the three is sending a different message than the others. The information lives in which layer is dissenting and why — the fast crowd, the medium-clock internals that lead price, or the slow structural foundation. The Brief's whole job is to read that quarrel rather than any one number in isolation.
Cadence and scope. The Sibylline Brief is a daily read of one thing — the Sentinel Stack — built for the morning decision. The Aletheia Report is a weekly hunt across the entire market for under-leveraged divergences, with each call tracked over time. They complement each other; plenty of members keep both.
The gauges are theory-driven, hand-calibrated composites — the Brief reads and interprets them, it doesn't promise an outcome. There's no out-of-sample track record, and any probabilities shown are descriptive base rates of the model's own construction rather than empirical predictions. See the Full Disclaimer for the complete picture.
Stop choosing the indicator that agrees with you. Read the one that disagrees, and understand why. The Sibylline Brief lands before the open.
