Market Catalyst Scanner
for Active Traders
Every major stock move has a catalyst behind it. TradeAI News automatically detects, classifies, and scores market catalysts across all US equities — FDA decisions, earnings surprises, M&A announcements, SEC filings, and unusual positioning — with the exact dispatch time stamped on every alert.
Catalyst Types Covered
TradeAI News does not treat all catalysts equally. Each catalyst type activates specific modules in the 5-layer scoring pipeline, and the TMS score is calibrated to reflect the typical magnitude and persistence of moves associated with each catalyst category.
Automatic Catalyst Classification
Identifying that an event is significant is only half the problem. The other half is understanding what type of catalyst it is and how the market is likely to respond. An FDA approval for a small biotech requires completely different context than an earnings beat from a large-cap industrial company — even if both score similarly on raw sentiment.
TradeAI News handles this automatically through its catalyst classification layer. The classifier is trained on thousands of labeled financial events and achieves high accuracy in distinguishing catalyst types. This classification feeds downstream into specialized scoring modules — biotech FDA catalysts activate different models than earnings events — ensuring the TMS score is contextually appropriate for each event type.
The Financial Calendar
Knowing when catalysts are scheduled is as valuable as detecting them when they fire. The TradeAI News Financial Calendar shows upcoming: earnings dates with consensus EPS and revenue estimates, PDUFA (FDA drug review deadline) dates for biotech catalysts, Federal Reserve meeting dates and expected rate decision ranges, major economic data releases (CPI, NFP, PMI, GDP), and sector-specific events.
Scheduled events on the calendar automatically prime the detection pipeline — when the scheduled event time arrives, the system is ready to process the announcement as soon as it publishes.
Frequently Asked Questions
What is a market catalyst in trading?
A market catalyst is any event, announcement, or data point that materially changes the perceived value of a stock, causing significant buying or selling pressure. The most common catalyst types are earnings results, regulatory decisions (FDA approvals), corporate actions (M&A, spinoffs, buybacks), SEC filings (insider transactions, material events), and unusual positioning visible in public data (volume against baseline, options-market context). TradeAI News automatically detects, classifies, and scores catalysts using a 5-layer AI pipeline, so you don't need to monitor multiple sources simultaneously.
How does TradeAI News classify catalyst types?
Catalyst classification is performed by a fine-tuned NLP classifier within the TMS scoring pipeline, trained on thousands of labeled financial events. The classifier identifies the primary catalyst category (FDA, earnings, M&A, SEC filing, analyst action, unusual volume) and any secondary categories. Classification determines which scoring modules activate — for example, an FDA catalyst activates specialized biotech regulatory context models, while an earnings catalyst activates consensus comparison models.
Which catalyst types produce the largest stock moves?
FDA decisions historically produce the largest percentage moves for individual stocks — biotech approvals and rejections regularly move stocks 50–200%+ in a single session. Earnings surprises (beats/misses) are the most frequent large-move catalyst, particularly for stocks with high short interest or elevated implied volatility going into the report. M&A announcements typically produce 20–40% moves in the target company. The TradeAI News TMS score accounts for catalyst type when weighting components — FDA events are evaluated differently than analyst actions.
How fast does TradeAI News detect catalysts?
Ingestion runs on a continuous loop across all the named feeds, so an event is picked up in the polling cycle in which it is published. Every alert is stamped with its exact dispatch time, and we publish the measured end-to-end median as the data accumulates — a number with a date, not a rounded promise. The clock starts at detection, not at our ingestion.
Does the catalyst scanner include a financial calendar?
Yes. The TradeAI News dashboard includes a Financial Calendar that shows upcoming scheduled catalysts: earnings dates (with consensus estimates when available), PDUFA dates (FDA drug review deadlines), Federal Reserve meetings, economic data releases (CPI, jobs report, PMI), and major sector events. The calendar helps traders prepare for known catalyst dates and position accordingly. Scheduled events on the calendar automatically trigger the detection pipeline at their scheduled time.
Can I get alerts for specific catalyst types?
The dashboard filters allow you to view events by catalyst type (e.g., show only FDA events). Email alerts and Telegram alerts are not currently filterable by catalyst type — you receive all events above your plan's TMS threshold. The REST API (Elite plan) supports catalyst type filtering via query parameters, allowing you to build a programmatic feed of only the catalyst types relevant to your strategy.
