A price jump is an invitation to investigate, not proof that a particular headline caused it. News can change beliefs, attract new participation or temporarily alter liquidity. The challenge is to identify what became known, when it became known and whether it changes the contract’s outcome.
Build a timeline before an explanation
Record the observation time, the publication time of the original evidence and any known earlier availability. A later article may summarize a document that was already public. If the market moved before the article, that article is not necessarily the trigger. Preserve time zones and distinguish publication from revision timestamps to avoid imposing a neat causal story on a messy sequence.
Read beyond the headline
Find the primary statement, report or result and compare it with the market rules. A headline can omit a deadline, a condition or a qualification that matters to settlement. Separate confirmed facts from interpretations and anonymous claims. If several outlets repeat one source, treat the information as one underlying signal rather than multiplying its weight by the number of articles.
Consider liquidity as an alternative
A relatively small trade can change a thin market’s displayed price. Check executable quotes and quantities alongside the chart. An unusually large move may reflect changed beliefs, a missing order or a stale observation. If the evidence is incomplete, describe several explanations rather than declaring the movement irrational or assuming that every trader has access to information you lack.
Update a written forecast
State which assumption changed and how much it changes your estimate. Compare that revision with the executable market price only after you articulate the reasoning. Keep both versions of the note so a later outcome review can evaluate the update. Chasing a move without a revised event model turns a research decision into an execution decision whose justification may disappear when the price reverses.
Questions & answers
Does every price move reflect new facts?
No. Liquidity changes, trading activity and display conventions can also affect observed pricing.
Why preserve timestamps?
They help distinguish information available beforehand from explanations assembled after a market moved.
