Catalysts

A catalyst is a scheduled or expected event — a regulator’s decision, a court date, a product verdict — that can move a stock sharply when it lands. The catalyst board collects them across the market so the date never takes you by surprise.

Reading a catalyst card

• Headline — what the event is, in one plain sentence.
• Expected date — our best estimate of when the decision lands. Some events have exact dates; others are windows — the card says which.
• Impact score — how much the outcome could plausibly move the stock, considering the company’s size and the event’s weight. Higher = potentially bigger swing — in either direction.
• Revised chip — dates change in the real world. When a timeline moves, we show the revision instead of silently rewriting history.

Two boards

The board is split into Sub-$100M (very small companies, where a single event can be transformative) and Biotech (all sizes — trial results and approval decisions are the classic catalysts). Use the filters in the sidebar to narrow by event type.
