Insider moves
Open-market purchases and sales by officers, directors, and large holders — read with role, size, and pattern context rather than as raw headlines.
What is Buteon?
Buteon turns market evidence into clearer reads. It is a research tool that watches insider moves, SEC filings, and market reaction — then lays out what happened, whether it seems to matter, what weakens that read, and what happened after similar cases.
The product
A lens for deciding what deserves attention.
Markets produce a constant stream of activity — filings, insider transactions, ownership changes, price moves. Most of it is routine. The hard part is not seeing the activity; it is deciding which of it deserves a closer look.
Buteon is built for that decision. It structures market-relevant events into evidence, weighs source quality, timing, and context, and presents each one as a read: what happened, why it may matter, what weakens it, and what would confirm or invalidate it. The goal is fewer, better-framed questions — not more alerts.
Signal intelligence, defined
“Signal intelligence” here means treating market events the way a careful analyst treats raw reporting: as claims to be weighed, not conclusions to be repeated. In practice that means collecting events from public sources, grading who acted and under what circumstances, separating measured fact from interpretation, and keeping a record of what happened after similar events — so today’s read is disciplined by yesterday’s evidence.
The problem
The same event can mean very different things.
An insider purchase can reflect genuine conviction — or a routine, pre-scheduled transaction. A filing can carry new information — or restate what the market already knows. The event is identical on paper; the meaning depends on who acted, when, at what size, and what surrounded it.
Tools that only surface raw activity push the interpretation work onto the reader. Buteon’s job is that interpretation layer — with the uncertainty stated, not hidden. If a read is weak, developing, or non-actionable, the product says so in those words.
Evidence stack
What Buteon watches.
Each read is assembled from layers of evidence, each with its own provenance and its own limits.
SEC filings
Structured public disclosures, starting with Form 4. Buteon reads them for what actually changed, not just for the fact that something was filed.
Actor behavior
How a specific insider has acted before at the same company — repeat patterns and prior measured activity, always with sample size stated.
Market reaction
How price and volume behaved around the event — used as confirmation context for a read, never as a forecast.
Outcome memory
What happened after similar past signals, recorded as measured cases with honest sample sizes. Historical context, not a performance claim.
AI-assisted interpretation
An optional plain-English brief, available on demand where enabled, narrates the structured read. AI does not change its evidence, score, or verdict.

From a raw filing to a structured read, in one disciplined pass.

- 01
What happened
The measured facts of the event: who acted, in what role, at what size, on what date, disclosed in which filing.
- 02
Whether it matters
A verdict-style read with confidence and freshness attached. When the evidence is thin, Buteon says so — a signal can be marked as still developing (watching) or non-actionable instead of being dressed up.
- 03
What strengthens it — and what weakens it
Supporting evidence and contradictions are shown side by side: routine explanations, offsetting activity, timing caveats, and risk context are stated up front, not buried.
- 04
What could confirm or invalidate it
Concrete conditions to watch. A read is a hypothesis about evidence, so Buteon states what would support it and what would break it.
- 05
What happened after similar cases
Outcome memory shows measured cases from comparable past signals — fraction-first and sample-size-aware, so a thin sample is never presented as proof.
Where AI fits
AI-assisted, not AI-hyped.
Buteon starts with SEC filings and deterministic, rule-based analysis. When available, an on-demand AI explanation layer turns that structured intelligence into a plain-English brief.
The brief does not collect filings, set scores, change verdicts, or provide investment recommendations; source evidence remains authoritative.
What AI does here
- Narrates the structured read. Turns existing intelligence into a concise, plain-English brief.
- Explains supplied factors. Describes the strengths and weaknesses already present in the rule-based analysis.
- Preserves the verdict boundary. Uses the existing verdict instead of creating a second conclusion.
- Runs only on demand. The optional brief is requested by the user; availability may vary.
What AI never does here
- Collect or verify filings. Source ingestion and review remain separate from the explanation layer.
- Set a score or verdict. Those outputs are determined before a brief is requested.
- Replace missing evidence. A fluent narrative cannot supply facts that the structured record does not contain.
- Give buy or sell instructions. Buteon is a research tool, not an adviser.
Built at the frontier. Grounded in evidence.
Buteon is developed and rigorously evaluated with frontier AI-assisted engineering, research, and quality-assurance workflows. These tools help us challenge assumptions, test product behavior, and improve how complex intelligence is presented. The edge is not any single model—it is the way evidence, timing, actors, contradictions, and outcome memory are assembled into one disciplined read. Buteon’s live verdicts remain anchored to SEC filings, deterministic analysis, and reviewed evidence, while the system around them is continuously tested, refined, and improved—day after day.
Trust
What Buteon is not.
A research tool earns trust by being precise about its own limits.
- Not investment advice.Buteon does not tell users what to buy, sell, or hold. A read describes evidence; the decision stays with the reader.
- Not a broker or custodian.Buteon does not hold funds, execute trades, or route orders anywhere.
- Not a copy-trading product.There is no “follow this insider” button, and there never will be. Insider activity is evidence to weigh, not a playbook to mirror.
- Not a guaranteed-return system.Markets are uncertain. Buteon makes no promises about results, and treats any claim of certainty as a defect.
- Not a buy/sell signal seller.Verdicts are structured reads on evidence — including “non-actionable” — not trade instructions.
- Not an AI stock picker.The optional AI brief explains an existing structured read in plain English. It does not pick winners, and Buteon does not claim it can.
