Primary evidence first
We start with the company release, investor presentation, SEC filing, official economic release, or exchange notice whenever one is available. A headline is a lead, not proof.

Editorial standards
Clear market explanations need evidence, not confidence theater.
WhyStockMove is an educational market-research product built to answer a narrow question: what evidence best explains why a stock is moving? We combine public market data, linked reporting, and official disclosures, then separate the verified event from the interpretation around it.

The four rules behind every guide
Expectation before reaction
A positive event can send a stock lower and a negative event can lift it. We compare the new fact with what the market had already priced instead of labeling every green move good and every red move bad.
Mechanism over storytelling
Each explanation should identify the channel connecting an event to price: earnings estimates, discount rates, share supply, forced flows, liquidity, or positioning.
Uncertainty stays visible
Public data cannot reveal the motive behind every trade. We distinguish verified facts from interpretation and avoid presenting a likely driver as a guaranteed cause.
How a stock-move explanation is built
- 1
Establish the clock
We match the price move with the release, filing, economic event, or trading-session window that occurred before it.
- 2
Read the original material
Where possible, we check SEC EDGAR, issuer investor-relations material, official economic releases, and exchange notices before relying on commentary.
- 3
Map the transmission channel
We ask which input changed: revenue, margin, cash flow, financing cost, risk, share count, liquidity, or a participant’s need to hedge.
- 4
Cross-check the reaction
Volume, peers, yields, options positioning, and later estimate changes can confirm—or contradict—the first explanation.
- 5
State the limit
An explanation is a supported interpretation of public evidence, not proof of every buyer’s or seller’s motive and not a prediction.
