Model Limitations

Probabilistic outputs

Forecasts, confidence ranges, anomaly scores, scenario stress tests, correlation tables, and consensus model views express possible relationships under stated assumptions. They can be wrong. Commodity markets can reprice around weather, geopolitical events, logistics constraints, exchange disruptions, inventory changes, policy announcements, or data-provider revisions that a model did not anticipate.

Scenario tools and user assumptions

Shock simulators, stress tests, event-probability views, and policy labs depend on user inputs and simplified assumptions. A scenario is a structured question, not a prediction. If a user selects an oil +30% shock or a copper -25% stress, the output estimates a possible exposure route; it does not know the user’s full financial situation, risk tolerance, tax position, cash needs, or compliance obligations.

Proxy data and sparse markets

Some commodities have direct futures benchmarks; others require proxies such as related equities, ETFs, regional benchmarks, public datasets, or manually curated reference series. Proxy data can diverge from the physical commodity, especially when a company has hedges, mixed business lines, regional pricing differences, or idiosyncratic corporate events. CommodityNode should label proxy context and avoid presenting proxy series as perfect spot prices.

Model drift and regime shifts

Relationships between commodities, companies, sectors, currencies, and macro variables can change. A historical correlation can weaken, invert, or disappear after a policy shift, capacity expansion, geopolitical conflict, subsidy change, inventory drawdown, or technology transition. Model drift may occur without warning and may not be visible until after a material miss.

Benchmark and backtest limits

Backtests and benchmark comparisons are internal research tools unless explicitly described otherwise. They may use historical data that was cleaner or more complete than real-time data, and they may not include all costs, liquidity constraints, revisions, survivorship effects, or operational frictions. Past model performance, historical hit rates, and previous scenario behavior do not guarantee future behavior.

Human review and correction handling

AI-assisted research can accelerate source comparison, chart summarization, entity mapping, and memo drafting. It can also miss context, hallucinate relationships, overstate certainty, or fail to notice stale data. CommodityNode uses editorial review, methodology notes, correction paths, and source labels to reduce this risk, but users should verify important facts independently. Report suspected issues through Corrections Policy.

Responsible use

• Use CommodityNode to frame research questions, exposure routes, and supply-chain scenarios.
• Do not treat a score, chart, forecast, range, or memo as a buy/sell/hold instruction.
• Check timestamps, units, source labels, and proxy limitations before relying on an output.
• Consult qualified advisors for regulated financial, legal, tax, or procurement decisions when appropriate.

Interpretability limits

Even when a model provides a plausible explanation, the explanation may be incomplete. A price move can reflect several forces at once: inventory, currency, policy, risk premium, weather, speculative positioning, refinery margins, freight, and company-specific news. CommodityNode may simplify these forces into readable memos, but simplification is not proof that the causal chain is complete.

Operational limits

Data pipelines can fail. A provider can change a ticker, delay a file, revise history, block an endpoint, or alter units. A static site deploy can show an older snapshot while a refresh is queued. When this happens, the safest response is transparent archive wording, source notes, and correction handling — not pretending that every page is live.

Reader checks before reliance

Before using an output, check the timestamp, unit, commodity benchmark, company mapping, and whether the page uses direct futures data or a proxy. Compare the conclusion against at least one primary source and one independent context source. If the output affects capital, procurement, legal, or operational decisions, involve qualified professionals and internal controls.

Research-only boundary: CommodityNode is research-only, not investment advice, and not trade alerts. Correction requests should use the public corrections workflow when a factual source, timestamp, unit, or limitation needs review.
