What Kinds of News Actually Move Prices?
Material catalysts include earnings, guidance revisions, M&A, FDA and clinical updates, product launches, large contracts, executive changes, short interest reports, analyst actions, and macro or sector shocks. Non-material headlines recycle known information or vague color and rarely sustain volume. Magnitude depends on surprise versus prior expectations, company size, float, and whether options and borrow markets were already pricing a binary outcome. Sector contagion can move peers even without company-specific text. Traders triage news by economic content first—does this change cash flows or risk—then by tradability.
Write a one-line thesis: “this changes X about the business or float,” or pass the ticker.
How Do Price and Volume Reflect News Quality?
High-quality surprises usually gap with elevated relative volume that persists beyond the first spike. Weak news prints a brief pop or dump on thin size, then mean-reverts as inventory rebalances. Watch bid-ask behavior: real sponsorship supports tighter markets after the initial shock; rumor-chasing leaves wide spreads and failed follow-through. Intraday, news that hits into lunch often has shorter legs than opening-drive catalysts. Compare percent move to ATR—one ATR news moves are commonplace; multi-ATR moves need corresponding volume to justify continuation entries.
If RVOL collapses while price still looks extended, continuation risk rises sharply for late longs or shorts.
What Risks Come With Trading News?
Headline risk compounds: updates, corrections, and denials arrive after you are already positioned. Halts interrupt exits. Illiquid names gap beyond stops. Narrative bias makes you hold losers because the story “should” work. Social amplification can invent urgency without institutional participation. False specificity—trading on anonymous rumors—creates one-way traps. Risk also includes opportunity cost: spinning through every wire headline prevents deep work on A-list setups with clearer structure.
Size news trades smaller than routine technical trades until liquidity and narrative confirm.
How Do Traders Plan Entries and Exits on News?
Build a focus list of researched names before the session so unexpected headlines land on familiar books. Prefer trading reaction structure—reclaim of pre-news level, hold of VWAP, opening-range breaks—over market buying the first green bar. Define invalidation as loss of that structure on a closing basis for your timeframe. Scale out into extensions; leave runners only when volume stays elevated. Stand aside when the news is ambiguous or the spread destroys edge. Pair news with liquidity filters: price floor, average volume, and today’s dollar volume.
Time-box research after a headline—two minutes to accept, reject, or wait; then move on.
What Mistakes Undermine News Trading?
Equating any headline with a trade. Ignoring whether the information was already discounted. Chasing after the easy money already printed. Averaging into failed news highs. Confusing sector ETF moves with single-stock edge. Trading every biotech binary without understanding asymmetric halt and gap risk. Effective news trading is selective: few catalysts per week, strict liquidity rules, and exits based on price structure—not loyalty to the story that got you in.
Log faded headlines that never produced RVOL; train yourself to skip that news class next time.
