Catalyst Calendar — Earnings and How (Not) to Trade Around Them

Most beginner losses don't occur because they picked the wrong stock. They happen because they held a good stock on a bad day — and that day was almost always the day of the quarterly earnings release. The Catalyst Calendar (tab Earnings Catalyst, /catalyst-calendar) exists so that this day never catches you off guard. It's not a tool for gambling — it's a planning map.

What is a Catalyst?

A catalyst is an event that can sharply move the price within minutes/hours. The market prices in expectations, and when reality is revealed, the price adjusts based on how much it differed.

Type	What it is	Impact
Earnings	Quarterly results + outlook	±5 to ±20%, most common and riskiest
FDA approval/data	Drug, clinical trial	±30 to ±80% in biotech, binary
M&A	Merger/acquisition	Target +20 to +40% jump
Stock split	Division (10:1)	Small direct impact
Ex-dividend date	End of dividend entitlement	Price drops ~by the dividend amount
Seasonal windows	Strong/weak period	Gradual, tendency not certainty

★ Insight: A stock doesn't react to whether a company made a profit — it reacts to whether it made more or less than expected. A company can have record profits and still drop 15% because the market expected even more.

Why Earnings Day is the Riskiest Day in a Stock's Life

Even if you have an A++ score and all five pillars are green, no one knows in advance what the CEO will say about the outlook. And it's precisely the guidance (outlook) that moves the price more than the achieved numbers. Why ±10–20% in minutes:

• Consensus is narrow — any deviation is sharply repriced.
• Implied volatility collapses after the report (IV crush).
• Liquidity after closing is thin (after-hours, pre-market = wilder moves).
• Guidance > past — weak outlook can sink even a record quarter.

★ Insight: Earnings day turns an investment into a gamble. For a few minutes, the market is a binary roulette — no one outside knows the new information. A prudent approach isn't "how to profit from earnings," but "how to manage risk around earnings."

PEAD — A Tradable Phenomenon After Results

PEAD = Post-Earnings Announcement Drift. After a sharp reaction to earnings, a stock often continues in the same direction for days to weeks. The market doesn't process the surprise immediately — institutions accumulate gradually, analysts adjust estimates with a delay.

Feature	Bet BEFORE	PEAD (AFTER)
What you do	Speculate on an unknown outcome	React to an already known outcome
Risk	Binary	Drift may not occur
Information	None extra	You have numbers and market reaction
Suitable for	Advanced, small position	Beginners and advanced

★ Insight: PEAD is beautiful because you don't have to guess. Let the report happen, see if the company surprised positively with the price reaction, and only then consider entry. Drift isn't a law of nature — it's a tendency that can fail.

---

Beat Rate — Context, Not a Guarantee

Beat rate = how often a company has exceeded estimates in the past. IS a measure of consistency. IS NOT a guarantee it will exceed next time, nor a prediction of price reaction.

★ Insight: A high beat rate can paradoxically be a trap. If the market "knows" the company always exceeds, it's priced in — and exceeding won't move the price (or disappoints if it was less than usual).

---

Two Strategies

A — Play BEFORE earnings (risky, for advanced): bet on an unknown outcome. Plus: you catch the entire jump. Minus: binary risk, stop won't protect you (gap over stop in after-hours). If you do it: drastically reduce position size, never more than you're willing to lose at once.

B — Play AFTER earnings (PEAD, calmer): wait for the reaction, enter in the direction of the move. Plus: no binary risk, normal stop. Minus: you miss the initial jump. For most — and definitely beginners — the only sensible choice.

How to Avoid Earnings Surprises in Long-Term Positions

1. Consciously hold with a plan ("I'm long-term, won't sell even at −15%" — but decided IN ADVANCE).
2. Lighten up before earnings (sell a third).
3. Wait to buy until after earnings.

★ Insight: The worst is "having no plan" — holding because you forgot, and then panic selling at the bottom. The calendar exists so that "forgot" doesn't happen to you.

Connections

Flow	What you do
Catalyst → Screener (Earn column)	Countdown to earnings — avoid entry just before
Catalyst → Transcripts (after report)	AI analysis of the call — management tone, clarity of outlook → PEAD entry
Catalyst → Journal	Plan for each event

---

Practical Steps

1. On Monday, note earnings in your portfolio/watchlist for 10 days.
2. For each position, decide in advance: hold / lighten / wait.
3. New purchase in a stock with earnings in ~7 days → wait for the report.
4. After the report: Transcripts + price reaction → PEAD entry in the direction of the reaction.
5. Record everything in the journal.

---

Tips

1. Never enter 1–3 days before earnings without a plan.
2. Hold through earnings only consciously and pre-decided.
3. PEAD catches direction only after the reaction.
4. Read beat rate as context, not a bet.
5. Reduce position when a catalyst is in the way.

Common Mistakes

Holding through earnings without a plan · speculating on the outcome · reading beat rate as a guarantee · relying on stop-loss through earnings (gap skips stop) · entering just before the report with full size.

Summary

The Catalyst Calendar is a defense against the most dangerous day in a stock's life. Don't use it for gambling — use it to know in advance and have a plan. Earnings day turns an investment into a gamble; PEAD offers a calmer, factual path after the reality is revealed. Beat rate is context, not prophecy. And the best trade around earnings is often the one you don't make.

Trading around earnings carries exceptionally high risk — ±10–20% in minutes and stop-loss may not work through after-hours gaps. QMA is an analytical platform; it does not provide specific buy/sell instructions. Decisions are made at your own risk. Past performance and beat rate are not guarantees.*
