News Research
How to review stock news before trading or paper-testing a market idea.
News can explain why a stock is moving, but it can also arrive late, spread through weak sources, or describe a move the market already priced in. A research workflow should check source quality before turning headlines into confidence.

Check Source And Timing
Record where the news came from, when it was published, whether it is primary or secondary, and whether the stock had already moved before the headline was reviewed. Timing matters because a good headline can still be a poor trade input if the market already reacted.
For filings, earnings, guidance, analyst changes, or company announcements, prefer original sources when available. For market commentary, separate confirmed facts from interpretation.
Connect News To The Thesis
Ask what the news changes: revenue expectations, regulatory risk, product demand, balance sheet risk, liquidity, sector sentiment, or short-term attention. If the news does not change the thesis, it may only be background noise.
Original source
Can the claim be traced to a filing, company release, exchange notice, or direct statement?
Publication time
Was the news available before the move being studied, or only after it?
Thesis impact
Does the news change revenue, risk, timing, liquidity, sentiment, or only the narrative?
Market reaction
Did price and volume already reflect the event before the review started?
Follow-up risk
Is there another filing, earnings call, regulatory step, or guidance update still pending?
Review After The Move
When the setup is reviewed later, compare the original headline and source quality with the actual price behavior. This helps distinguish useful catalysts from headlines that only felt important in the moment.
A strong review asks whether the headline created new information, confirmed an existing thesis, or simply gave a story to price action that was already underway. Those are different lessons.
When news should slow the process down
Wait when the source is unclear, when a headline lacks the original filing or release, when the market already moved sharply, or when the event creates uncertainty that cannot be measured yet. Not every news item deserves a paper trade.
For options, sudden news can also widen spreads and raise implied volatility. That means a contract can become harder to review even when the stock thesis becomes more interesting.
Common questions
How do I know if stock news is useful for research?+
Useful news changes something about the thesis: earnings expectations, guidance, regulation, product demand, balance sheet risk, or sentiment. If it does not change the thesis, it may be background noise.
Why does headline timing matter?+
A headline can be true but late. If the stock already moved before the news was reviewed, the risk/reward and paper-test assumptions may be very different.
Should I trust summaries or original sources?+
Prefer original sources when available, especially for filings, earnings, company announcements, and regulatory news. Summaries can help discovery but should not replace source review.
