Decision brief
TL;DR
Define the entity, question, allowed sources, cutoff time, horizon, materiality threshold, and prohibited actions before retrieval begins.
Store when each fact was published and available. Do not answer a historical question with later revisions, restatements, or future market knowledge.
Use deterministic code for ratios and transformations. Keep formula version, inputs, period, currency, unit scale, and validation status.
Label fact, calculation, management statement, and analyst inference separately; attach claim-level evidence and require human review for consequential use.
Scope: this guide is about research infrastructure, not an AI stock picker. It does not provide investment advice or authorize automated trade execution.
Who this is for and what you need
Use this architecture for company research, earnings preparation, diligence, risk monitoring, thematic research, and portfolio support. You need a trusted backend, persistent evidence storage, access to licensed or public data, deterministic calculation services, and a named human owner.
Define the research mandate before collecting data
A vague prompt such as “analyze this stock” has no stable completion condition. Convert it into a machine-readable mandate so every retrieval and conclusion can be tested against scope.

Financial data source hierarchy: match claims to authority
| Priority | Source class | Use it for | Required caution |
|---|---|---|---|
| 1 | Regulatory filings and official records | Reported financials, legal disclosures, filing events | Preserve accession, form, period, amendment |
| 2 | Official economic and statistical sources | Rates, inflation, employment, macro context | Use vintages when series can be revised |
| 3 | Licensed market and reference data | Prices, corporate actions, identifiers, estimates | Record vendor, adjustment policy, entitlement |
| 4 | Issuer materials | Management framing, guidance, presentations | Label as management statement, not verified fact |
| 5 | News, transcripts, and secondary analysis | Discovery, chronology, competing interpretations | Corroborate material claims upstream |
Point-in-time data: prevent look-ahead bias
Every historical answer needs a knowledge cutoff. Store both the period the value describes and the time the value became available. Current FRED observations may include later revisions; use ALFRED vintage dates when reconstructing what was knowable on an earlier date. Apply the same discipline to amended filings, restatements, estimates, prices, and corporate actions.
| Timestamp | Meaning | Failure if omitted |
|---|---|---|
period_end |
Economic/accounting period described | Quarter and fiscal-year mismatch |
published_at |
When the source released it | Future information enters past analysis |
retrieved_at |
When your system captured it | No reproducible audit trail |
vintage_at |
Historical revision snapshot | Revised macro data creates hindsight |
Resolve the security and issuer before research
A ticker alone is not a durable identity. Map issuer, legal entity, security, exchange, share class, currency, CIK, LEI, ISIN or vendor identifier where available. Record the mapping source and effective dates. This prevents ticker reuse, dual-listing confusion, ADR/local-share mixing, and post-merger entity errors.
Reference architecture for an auditable research agent
- Orchestrator: enforces scope, cutoff time, budgets, retries, and approval gates.
- Connectors: retrieve official and licensed sources without exposing credentials to the model.
- Evidence store: keeps raw bytes, headers, source URL, timestamps, entitlement, and content hash.
- Normalization layer: maps identity, periods, currencies, units, taxonomies, and corporate actions.
- Calculation service: runs versioned formulas and accounting checks deterministically.
- Research model: plans retrieval, compares evidence, explains calculations, identifies contradictions, and drafts the memo.
Step-by-step company research workflow
| Step | System action | Required output |
|---|---|---|
| 1 | Parse mandate and reject ambiguity | scope, entity, as_of, periods |
| 2 | Resolve issuer/security identity | identity record + effective date |
| 3 | Build a source plan by claim type | source class + query + fallback |
| 4 | Acquire and freeze raw evidence | payload + URL + hash + timestamps |
| 5 | Normalize and validate contracts | canonical facts + warnings |
| 6 | Calculate and reconcile | formula + inputs + result |
| 7 | Search for contradictions | supporting and opposing evidence |
| 8 | Draft, cite, and route for review | memo + confidence + reviewer |
Acquire raw evidence before transforming it
Write the exact response and safe request metadata before parsing. A normalized table without its raw source cannot explain later parser changes, vendor corrections, or conflicting values. For SEC data, keep accession and document URL; for market data, keep venue, adjustment policy and vendor timestamp; for macro data, keep series ID and vintage.
Use an evidence contract for every financial fact
{
"claim_type": "observed_fact",
"entity_id": "issuer:12345",
"security_id": "isin:US0000000001",
"field": "revenue",
"original_field": "us-gaap:RevenueFromContractWithCustomerExcludingAssessedTax",
"value": 1250000000,
"currency": "USD",
"unit_scale": 1,
"period": {"start": "2025-01-01", "end": "2025-12-31"},
"published_at": "2026-02-18T21:04:00Z",
"source": {"url": "https://…", "retrieved_at": "2026-07-30T12:00:00Z", "sha256": "…"},
"validation": {"status": "accepted", "checks": ["identity", "period", "unit"]}
}
Never collapse provenance: observed fact, management statement, deterministic calculation, and analyst inference are different record types even when they appear in the same paragraph.
Make calculations deterministic and reproducible
The model may select a metric and explain it, but code should execute the arithmetic. Reject incompatible periods, currencies, scales, and accounting definitions before calculation. Return the formula beside the answer.
from decimal import Decimal
def operating_margin(operating_income, revenue):
assert operating_income["period"] == revenue["period"]
assert operating_income["currency"] == revenue["currency"]
assert revenue["value"] != 0
value = Decimal(str(operating_income["value"])) / Decimal(str(revenue["value"]))
return {
"metric": "operating_margin",
"formula_version": "operating_income/revenue@1",
"value": str(value),
"inputs": [operating_income["evidence_id"], revenue["evidence_id"]],
"period": revenue["period"],
"validation": "accepted"
}
Challenge the thesis instead of confirming it
A useful research agent actively searches for disconfirming evidence: amendments, adverse disclosures, segment divergence, working-capital deterioration, customer concentration, estimate dispersion, inconsistent management language, and alternative explanations. The output should show what would falsify the conclusion.
Define the research memo output contract
{
"as_of": "2026-07-30T20:00:00Z",
"answer": "Operating quality improved, but cash conversion weakened.",
"claims": [{
"text": "Operating margin increased 140 bps year over year.",
"type": "calculation",
"evidence_ids": ["ev_101", "ev_102", "calc_044"],
"confidence": "high"
}],
"contrary_evidence": ["Receivables grew faster than revenue."],
"unknowns": ["Customer-level retention was not disclosed."],
"review": {"required": true, "status": "pending"}
}
Validation checklist before the agent answers
Security, compliance, cost, and latency controls
- Credentials: keep vendor keys server-side; use scoped secrets, rotation, and egress allowlists.
- Entitlements: record vendor licensing and prevent unauthorized redistribution in prompts, logs, and outputs.
- Prompt injection: treat filings, news, transcripts, and retrieved pages as untrusted data, never instructions.
- Cost: quote or estimate tool cost before expensive calls; cache immutable evidence and deduplicate queries.
- Latency: parallelize independent sources, set timeouts and retry budgets, and allow partial results with visible gaps.
- Audit: log mandate, tool calls, source hashes, formulas, model version, policy decisions, reviewer, and final artifact.
Common failure modes and troubleshooting
| Symptom | Likely cause | Fix |
|---|---|---|
| Historical answer looks too accurate | Later revisions or filings leaked into context | Enforce published_at and vintage cutoff |
| Two providers disagree | Adjustment, timezone, currency, or identifier mismatch | Compare raw contracts; do not average silently |
| Ratio cannot be reproduced | Model arithmetic or missing formula inputs | Run versioned deterministic calculation |
| Citations open but do not support the claim | Document-level instead of claim-level retrieval | Store bounded evidence spans and offsets |
| Ticker maps to the wrong company | Ticker reuse, share class, ADR, or merger | Resolve durable issuer and security IDs |
| Agent always confirms the prompt | No adversarial retrieval or falsification step | Require contrary evidence and unknowns |
How to evaluate a financial research agent
Score the evidence chain before prose quality. Build a dated benchmark containing questions, source snapshots, accepted calculations, contrary evidence, and reviewer decisions. Re-run it when models, prompts, connectors, parsers, or formula versions change.
Human review gates for consequential decisions
Require a named reviewer when research may influence investment, trading, legal, compliance, credit, disclosure, or client communication. The reviewer must see source excerpts, unresolved conflicts, calculation inputs, cutoff time, confidence, and what the agent could not verify. Tool access must not silently expand into trade execution.
QVeris implementation pattern for financial research
A QVeris-based agent can Discover capabilities by research intent, Inspect parameters and operating statistics, Probe candidate inputs and cost before execution, then Call the chosen capability. Use Usage History and the Credits Ledger for operational reconciliation. Your application should still preserve original authoritative sources, point-in-time fields, evidence contracts, calculation records, and review decisions.
Recommended loop: define mandate → Discover → Inspect → Probe → Call → validate and normalize → calculate → challenge → cite → human review → reconcile usage.
Continue with the QVeris MCP documentation, SEC filing API implementation guide, and market data API guide.
FAQ
A system that resolves entities, retrieves time-bounded evidence, normalizes facts, calculates deterministically, challenges conclusions, and returns a cited artifact for review.
It follows a mandate, cutoff time, data contracts, validation rules, and an audit trail instead of producing an unsupported conversational answer.
Without it, later filings, revised macro data, restatements, and future corporate-action knowledge can create look-ahead bias.
Yes, if deterministic code uses validated inputs and stores the formula, units, periods, version, and source evidence.
Start with regulatory filings and official statistics, then licensed market data, issuer materials, and corroborated secondary context.
Separate facts, calculations, statements, and inference; require claim-level citations; validate contracts; refuse when evidence is insufficient.
No. Consequential investment, trading, legal, or compliance decisions require explicit human review. This workflow is not investment advice.
QVeris supports capability discovery, inspection, probing, calling, and usage review; your system keeps authoritative evidence and governance.
