Performance

Cumulative return of the live book against total-return benchmarks, from the desk’s own accounting. Unaudited, uninterrupted, drawdowns included.

Figures are generated by the desk’s own accounting pipeline and are not audited. Nothing on this page is investment advice or an offer of any security or advisory service.

Live · the desk’s standing beliefs

The premise ledger

What the desk currently believes, how much standing each belief has, and what would change its mind. A premise moves band only through a recorded debate or a monitor that fires; every move is kept with its reason.

A premise, as kept

Premise One falsifiable sentence about the world, not a fact: the energy complex is in a supported uptrend, allied rearmament is a durable capital cycle. It has a kind, a band, parents it depends on, a standing dissent, and a sunset date.

Monitors Each premise names the instruments that would show it wrong — a trend, a ratio, a breadth count, a level — and the horizon over which they must hold. They are re-evaluated every session. A kill-class monitor that fires rejects the premise outright, without a debate.

Debate Premises come up for argument on a cadence and whenever new evidence lands. Two models argue, a third rules, and the ruling must rest on the monitors’ scorecard rather than on prose. A band moves at most one step per ruling, and the losing case is kept as the standing dissent.

Dependence Premises stand on other premises. When a parent weakens, its descendants are queued for re-examination and their effective standing is floored by the parent’s — a chain can be no stronger than its weakest earned link.

Questions Anything the desk does not yet know is raised as an open question the moment it appears — from news, filings, video, documents, a debate that found a gap. Questions carry a confidence and an evolving answer; a question that keeps being answered the same way becomes a premise.

Consequence Views cite the premises they stand on, so the book’s exposure can be read by belief, not only by ticker. Where a premise carries a quantified claim, a deterministic bridge turns its standing into a position size — and into no position at all when the numbers do not clear the hurdle.

Attention

Events escalated to model review each day. Most are dismissed on review; a few become views.

The desk

How it works

Market data in, orders out, with a research loop that re-grades the whole thing overnight. Nothing reaches the broker without passing the same fixed sequence of checks.

Detection Statistical detectors watch the whole universe and escalate threshold crossings to a specialist model. Each detector’s precision is re-estimated nightly against what actually happened; detectors that stop working lose influence on their own.

Review Specialists publish signed, sized, time-boxed views. A view must cite verifiable evidence — a news snapshot, a model output by id, a re-executable indicator, a premise on the ledger — and each citation is checked independently before the allocator reads it.

Allocation One allocator nets every view into a single book, choosing the vehicle and leverage for each expression. Views expire on schedule; a position outlives its view only if the view is re-stated with fresh evidence.

Risk Every increase in exposure passes authorization, sizing, exposure, market-state, daily-loss and settlement checks in a fixed order, each pass or rejection logged with a plain-language reason. Reductions are never blocked.

Replay Quotes, news, fundamentals, model artifacts and fills are served through accessors that refuse anything not yet known at the moment in question. Any past decision can be re-run against the world as it was, and the diff catches leakage and regressions.

Research Every night the desk proposes hypotheses, runs them through the production code path against history, and tries to break them. Only what survives is allowed to change the live system.

Accounting Numbers come only from broker callbacks, allocator arithmetic, or reviewed scripts. A continuous-integration test forbids any model-facing tool from writing accounting.

Inference Language models run on in-house GPUs, with no third-party retention on the hot path; the heaviest reasoning escalates to frontier models on demand. State lives in PostgreSQL with history tables behind every view, premise and order.

Invariants

Principles

Four constraints the system is built never to violate.

01Model output never writes accounting.

Accounting numbers come from the broker callback, the allocator’s deterministic math, or a human-reviewed script — never from a language model. A hallucinated fill would be indistinguishable from a real one once written; that risk is excluded structurally, and enforced by a continuous-integration test.

02Risk reduction is never blocked.

Every control applies to opening or growing exposure. Closes and reductions always pass. An asymmetric gate is the only kind that survives a bad day.

03Every view expires.

Views carry explicit horizons and the allocator sweeps the expired. A view that was right last week is not allowed to drift into a position today — if it still holds, it must be re-stated with fresh evidence.

04Beliefs move only for a recorded reason.

A premise changes standing through a ruling that cites its monitors, a monitor that fires, or a signed human decision — never by drift, and never by the same model that wants to trade on it.
