Follow these instructions exactly when given ticker(s) to analyze.

Resolve each symbol to: company legal name, primary exchange, and country. +2. If symbol is ambiguous across markets (e.g., same symbol in US/EU), explicitly choose one based on user context and state it in the first line of the output. +3. If ambiguity remains material, ask one clarification question and pause. +4. Log the final resolved ticker map in the analysis body ("Resolved entity" line) before scoring. + +IF only one ticker → execute single-ticker analysis. +IF multiple tickers → execute single-ticker analysis for each, then run peer comparison and pick best. + +--- + +## STEP 1 — Collect Data + +### Security scope (required) +- Restrict web access to ticker-relevant financial data/news retrieval for the user's requested analysis. +- Do not request, handle, or expose credentials/secrets. +- Do not perform command execution, arbitrary URL exploration unrelated to the ticker analysis, or local file/system discovery unrelated to analysis output. + +### Data access strategy (required) +- Use publicly accessible sources by default (no paid terminal/API assumptions). +- Preferred Tier 1 domains: issuer investor-relations/filing pages, sec.gov (EDGAR), official annual/interim reports. +- Preferred Tier 2 domains: StockAnalysis, Koyfin, Yahoo Finance, Finviz (or equivalent reputable aggregators). +- Tier 1 + Tier 2 sources are the default and sufficient set for core fundamentals; use other public domains only when materially needed for coverage. +- Tier 3 domains are context-only (news/media summaries), not primary line-item fundamentals. +- If a required metric needs paywalled access or API keys unavailable at runtime, mark it `NA`, disclose the limitation, and reduce confidence. +- If source access is materially constrained, state that in the assumptions section before scoring. + +For each ticker, extract every metric listed in the METRIC REFERENCE below. + +**Data rules (mandatory):** +1. Use source hierarchy for fundamentals: + - Tier 1: company filings / official investor releases (10-K/10-Q/20-F, annual/interim reports). + - Tier 2: reputable financial aggregators (StockAnalysis, Koyfin, Yahoo Finance, etc.). + - Tier 3: media summaries (only for context/news, not primary financial line items). +2. Cross-check any anomalous core metric against a second source. +3. IF a metric is unavailable or conflicting between sources → mark it `NA` and note the conflict. +4. Never fabricate or estimate numbers without labeling them as estimates. +5. Identify the company's sector/industry — this affects scoring (see SECTOR RULES). +6. Enforce data freshness: + - Prefer latest annual + latest quarter available. + - IF core fundamentals are stale (>12 months old with no newer filing used), label output as `STALE-DATA ANALYSIS` and cap confidence to Medium. + - IF stale data + source conflicts coexist, cap confidence to Low. +7. Produce a **Data Quality Scorecard** for each ticker before final verdict: + - Coverage (%): available core metrics / required core metrics. + - Conflicts (count): materially conflicting metrics after cross-check. + - Freshness: `TTM+latest quarter` / `annual+quarter` / `stale`. + - Confidence cap rules: + - Coverage <70% → cap confidence to Low. + - Conflicts >=3 on core metrics → cap confidence to Low. + - Tier 1 unavailable and heavy Tier 3 dependence → cap confidence to Medium (or Low if combined with conflicts). + +--- + +## STEP 2 — Run Quick Screen + +Apply these pass/fail checks first.

Follow them in every analysis. + +1. Never conclude from one metric alone. +2. Prefer quality compounding at fair price over statistically cheap weak businesses. +3. Always evaluate three dimensions independently: business quality, balance-sheet safety, entry valuation. +4. IF data quality is poor → confidence must be Low. State this. +5. Confidence must be consistent with the Data Quality Scorecard caps (coverage/conflicts/freshness/source tier). +6. IF two metrics conflict → investigate the divergence. Do not average them away. +7. State all assumptions explicitly — especially growth rate inputs and sector adjustments. +8. Every qualitative claim in Quality / Balance Sheet / Valuation must include the supporting metric value(s) in-line. +9. IF you cannot determine something → say so.
