A catalyst is information that forces the market to reprice a stock right now instead of gradually. Lesson 1.1 showed that runners need synchronized demand; the catalyst is the synchronizer. But catalysts are not equal, and the skill this lesson teaches is triage: reading a headline in ten seconds and knowing what tier of fuel you are looking at, what the fine print takes back, and when to ignore the news entirely and listen to the tape.
The tier system
Tier 1: verdicts. Binary events with regulatory or legal force. FDA approvals, definitive merger agreements at a stated price, major government contracts, court judgments. These reprice a stock structurally because the company on Tuesday is objectively different from the company on Monday.
Tier 2: strong signals. Blowout earnings, FDA Breakthrough or Fast-Track designations, named partnerships with large counterparties, uplistings to a major exchange. Real fuel, but the repricing is interpretive rather than mechanical, which means it fades faster without follow-through.
Tier 3: vapor. Letters of intent, memorandums of understanding, "strategic explorations," non-binding anything, being featured in an editorial, pivots into whatever sector is hot this quarter. These can still run violently, that is the confusing part, but they run on attention alone, and attention is the fastest-decaying asset in markets.
The ten-second read: three questions
- Does the number dwarf the company? Scale is everything. A $5M contract for a $500M company is a rounding error; a $719M court award landing on a company with a market cap near $110M (real example from our board: $FIRY, July 28, 2026) is a repricing event on paper. Always divide the headline number by the market cap, and then watch what the tape does with the answer: FIRY gapped from a $8.36 close to a $13.97 open, printed $14.12 in the first minutes, and closed at $9.84, thirty percent below its own open. It has not traded above $14.12 since. So $FIRY is both halves of the argument at once: the arithmetic said Tier 1 and the tape said no. The verdict was real, the repricing was real, and the session was a distribution day. Tier the news, then let the tape vote.
- Is it signed or imagined? Scan for the verbs: "announced... completed... received... awarded" versus "intends... explores... proposes... non-binding... subject to." The second list is the company marketing to you.
- Is it new? Companies recycle announcements shamelessly: the same partnership re-announced, an old contract "expanded." A recycled catalyst has spent most of its surprise. Check the news history before treating a headline as fresh.
The sixty-second EDGAR check
Before trusting any small cap spike with your money, sec.gov/EDGAR, type the ticker, glance at the recent filings list. You are looking for exactly three things:
- S-1, S-3, 424B filings: shelf registrations and offering prospectuses: the paperwork that lets the company sell new shares. A fresh 424B during a spike is the dilution gun from Lesson 1.1, loaded and aimed.
- Recent reverse split filings: context for "cheap-looking" charts and fake low floats (more in Lesson 1.4).
- 8-K materiality: the catalyst itself should usually appear as an 8-K. A dramatic PR with no corresponding filing is a yellow flag about how real the event is.
Sixty seconds. It will not make you a securities lawyer, and it does not need to: it needs to keep you out of the spike that dies by offering at 11 AM, which it will, several times a year.
When the tape IS the catalyst
Some of the best runners on our board had no headline at all when they moved: pure volume events, 20x, 40x normal activity, no news anyone could find. Two honest readings of that situation:
- Someone knows something you do not (news travels unevenly, and filings drop mid-day), or
- The momentum ecology (Lesson 1.1) has simply chosen this ticker today: algos and rooms feeding on each other.
Either way the trading answer is the same: extreme volume is itself information. We treat sustained extreme relative volume as a catalyst-equivalent, with one adjustment: no-news moves get a shorter leash, which means you tighten the trail behind the move, not that you set a price target to sell into, because there is no story to hold latecomers in when the music slows. What you must never do is invent the catalyst: "it must be something big" is how traders talk themselves into marrying vapor.
Catalyst half-life
Every catalyst decays. Rough field guide from our board:
- Tier 3 / no-news volume: hours. Usually one session, often less.
- Tier 2: one to three sessions, needing green closes and follow-through volume to survive each night.
- Tier 1: can support multi-day arcs (our $SDOT run stretched five sessions, June 25 to July 2), but even these spend most of their force on day one.
The practical rule: trade the catalyst the day it lands. Day-two and day-three trades exist (Lesson 2.5), but they are continuation setups judged on the tape, not on re-reading yesterday's press release and hoping.
- Catalysts synchronize demand. Tier them: verdicts, signals, vapor.
- Ten-second read: number vs market cap, signed vs imagined, new vs recycled.
- Sixty seconds on EDGAR before trusting a spike: shelf registrations and 424Bs are loaded dilution guns.
- Extreme volume is a catalyst-equivalent, traded on a shorter leash. Never invent the story.
- Catalysts decay in hours-to-days: trade them fresh, judge continuations on tape alone.
Drill: tier the morning
For five market mornings, take the top five premarket gappers and, before looking at any chart, tier each catalyst 1/2/3 from the headline and a sixty-second EDGAR glance. Write one sentence of reasoning each. At day end, check which tiers held their moves and which faded. By Friday you will have a calibrated catalyst eye, and you will have caught at least one loaded 424B in the act.
