A Lizard, a Dog, and a Professor Walk Into the SpaceX IPO

At the Trading Desk

Third in the At the Trading Desk series. Each entry sits with a single real session and the quiet psychological work it asked of the person watching it. The market events are exactly as they happened. The trader is a composite, the same one I have called Marcus in the first entry and again in the second, drawn from journals and conversations, with the details changed. The lessons are from Trade Calm.

On the morning the largest IPO in history opened, the most important trade was the one Marcus did not make.

The night before, Friday June 12, 2026, SpaceX had priced the biggest initial public offering ever recorded. It sold 555.6 million shares at 135 dollars each and raised about 75 billion dollars, a deal so large it did not edge past the old record, the 30 billion Saudi Aramco raised, it nearly tripled it. The valuation landed near 1.77 trillion dollars. By the opening bell, every feed Marcus had was already vertical about it. The chatter was not about whether to buy SPCX. It was about how much, and how fast.

It did not open at the bell. The opening auction spent the first stretch of the session hunting for a price, the indication ratcheting higher every few minutes while nobody could actually trade it. That delay is its own kind of pressure. It gives the room time to talk itself into a number. When it finally printed, it opened at 150, already above the 135 the insiders paid, and then it went to work on the people watching. It ran to a high of 176.52 by midday, halting for volatility along the way, and the whole cluster of adjacent names, the suppliers, the satellite tickers, the funds with a sliver of exposure, ran alongside it.

Marcus had a plan for the day, written the night before, when the only thing SPCX was doing was sitting in a headline. The plan had two setups on it, a daily loss limit, and one line he had added in plain language at the bottom: no IPO on day one. None of that mattered to what arrived the moment the first print crossed the tape.

Three Voices Share One Chair

What arrived was not one urge. It was three, and they did not want the same thing, and telling them apart is most of the job. The shorthand I use, the one Marcus uses, is the Lizard, the Dog, and the Professor. The Lizard trades to survive. The Dog trades for the treat. The Professor is the only one at the desk who has read the plan.

The picture comes from the triune brain, the model Paul MacLean popularized last century: an old reptilian core, a mammalian middle, a human cortex on top. Neuroscientists have spent decades complicating it, because the brain is not three clean layers stacked like sediment, and as literal anatomy it is dated. As a map of what happens to a person with size on and a screen going vertical, it still earns its keep, and that is the only test that matters at the desk. Daniel Kahneman drew the same line in cleaner terms: a fast system that reacts before you can think, and a slow one that thinks before you act. The Lizard and the Dog are the fast system. The Professor is the slow one. On a morning like this, the fast system has a head start measured in hundreds of milliseconds, and it spends every one of them.

The Lizard is the oldest part, and it has one job: keep you alive. It runs on the amygdala, it has no language, and it does not know the difference between a predator and a chart. It knows threat and it knows opportunity, and on an IPO morning it reads both at once. Get in, or get left behind to die. Notice that fear and greed are not opposites to the Lizard. They are the same circuit. The terror of missing the biggest move of the year and the terror of a drawdown are produced by the same hardware, which is why the trader most afraid of losing and the trader most afraid of missing out can look identical at the desk. They are both just scared. The Lizard does not build a case. It floods the body and waits for you to obey.

The Dog is the trained one. It lives in the reward system, it runs on dopamine, and it has a long memory for the treat. Every prior moonshot you watched run without you taught the Dog a lesson it never forgot: when the room gets loud like this, something good is about to happen, and you had better be there for it. Wolfram Schultz mapped this precisely. Dopamine is not the pleasure of the reward. It is the prediction of it, the signal that fires before the treat lands, the lean toward the bowl. The bell rang for the Dog the second SPCX hit the tape, and it had been conditioned by a hundred prior bells to do one thing. The Dog is not stupid. It is loyal, and it is fast, and it is loyal to the wrong scorecard. It wants the hit, and it wants to belong to the move everyone else is already in. Neither of those is on Marcus's page.

The Professor is the newest hire and the slowest. He lives in the prefrontal cortex, he is the part that wrote the plan the night before, and he is the only voice in the building that has read it. He thinks in probabilities, the way Mark Douglas spent a career teaching traders to. He can hold a stop, respect a trade count, and sit out a name that has no history and no level. He has one fatal weakness, and the market knows it: he is expensive to run, and he goes quiet under arousal. The exact moment you need him most, when the Lizard is flooding and the Dog is straining at the leash, is the moment the blood and the attention drain out of his office. He does not lose the argument. He just stops getting invited to it.

What the Three Wanted When SPCX Printed

So here is the desk when that first print hit. The Lizard went first, because it always does. No words, just a jolt: a tightness in the chest, a pull toward the buy button, the body certain that not acting was the dangerous choice. Then the Dog, with a story it had told before. You remember the last one of these that ran. You sat it out and watched it double. Not again. Get a starter on, you can manage it after. And underneath both, faint, the Professor, holding up a single index card: this is not on the page, it has no trading history, there is no level to lean on, the open of a brand new listing is the definition of a chase.

Three voices, one cursor. The Lizard wanted to survive the move. The Dog wanted the treat it had been trained for years to expect. The Professor wanted to follow the plan, and the plan said no. The vote was two to one, and the two were screaming, and the one was whispering. That is the real tally on a morning like this. If you let it get settled by volume, you buy the most exciting stock on earth at the precise moment the Lizard and the Dog are loudest, which is the precise moment you should trust them least.

What the Professor Actually Knows About IPOs

Here is the part the Lizard and the Dog never bother to learn, because learning is slow and they are not. Trading a brand new listing is its own discipline, with its own literature, and almost all of it argues against the thing they were demanding.

Start with the base rate. Jay Ritter at the University of Florida, the man the industry calls Mr. IPO, has tracked new issues for decades. Across 1980 to 2025, U.S. IPOs have averaged a first-day return of about 19 percent. The catch is in who collects it. Most of that pop goes to the institutions that received an allocation at the offer price the night before. SPCX priced at 135. The funds that were allocated bought at 135. The retail trader watching it print at 150 and run to 176 is not buying the pop. He is buying after it, from the person who already owns it and is delighted to hand it over.

Then there is the deeper problem, the one that should matter most to a technical trader: on day one there is nothing to lean on. No prior support, no resistance, no moving averages, no history of how this name behaves when it is scared. The opening hour is not a trend. It is raw price discovery, a live argument between the institutions who got the deal, the underwriters, and a flood of retail, all deciding what the thing is worth in real time, with spreads wide and swings violent.

Which is exactly why the people who trade first-day IPOs for a living refuse to touch the open. Scott Redler of T3 Live, the same trader whose moving-average framework I lean on elsewhere, has written for years about what he calls the Art of the First Day, and the striking thing about it is how much of it is simply waiting. He does not care about the valuation or the story. He wants levels to define risk against, and at the open there are none, so he lets the session build them. His first level is the opening print itself: give it time, and if the stock cannot get and hold above the price where it first opened, that is supply overwhelming demand, and the name is not worth trading that day. His second test is the first pivot high, the high of those opening minutes. A strong debut reclaims it and stays above it. A weak one gets rejected there, which tells you sellers are in control. The actual setup, when there is one, tends to come later, after supply floods in and knocks the stock off its highs, and only once it carves a higher low can the aggressive trader buy against that low with risk clearly defined. Redler had made the same point only weeks earlier about another hot deal that opened, ran, and never reclaimed its high, leaving everyone who chased it underwater for good.

Notice what is nowhere in that framework: buy the first print because it is SpaceX. The man who trades first-day IPOs for a living spends the open doing nothing, watching, letting the stock show its hand. The open, the exact moment the Lizard and the Dog were screaming at Marcus, is the one moment the professional refuses to act. Marcus's own line was blunter, because Marcus is not an IPO specialist. It just said no IPO on day one, full stop. The principle underneath both is the same. There is no edge in the open of a new listing. There is price discovery, a loud crowd, and three voices in your skull insisting that this time is different.

The Body Told on Him First

Marcus did not win this by arguing. You cannot argue a Lizard down; it has no language to argue in. He did the thing the book asks for before any trade that is not on the plan. He ran a short body audit. Antonio Damasio's work on somatic markers is the reason this works: the body registers the stakes before the conscious mind does, and you can read the decision in the body before you make it. His shoulders were up near his ears. His breath was high and shallow. He had pulled in close to the screen and was watching the halt timer instead of his own chart. His hand was already on the mouse. Not one of those is the signature of a trader executing a plan. All of them are the signature of a man being moved.

He took three slow breaths and sat back until he could see the whole screen again, not just the one name burning a hole in it. The urge did not vanish. It loosened by maybe ten percent, which is not much, and is everything, because ten percent is the gap between a reflex and a choice. In that gap the Professor got a word in. He named them, the way the book teaches and the way the last entry showed him naming the headline voices. Lizard. Dog. Naming a thing measurably loosens its grip within seconds. You are not fighting it. You are noticing it, and noticing is the one move the fast system cannot make on its own.

The Machine Had No Lizard

Days earlier I had written about an AI trading system we run in public, and that same week, the night SPCX priced, the machine faced this exact event. Its watchlist ripped, the whole adjacent group went euphoric, and the system, sitting in cash by rule, did not buy a single share. It was easy for the machine, and that is the part worth sitting with. The system has no amygdala, so it felt no jolt. It has no reward history, so no Dog strained at any leash. A brand new listing was ineligible by definition, a single euphoric session inside a structure with no history was a chase, and with nothing in the hardware pulling the other way, following the rule cost it nothing.

Marcus had to produce the same output the hard way. The machine skips the chase because it cannot want it. The human skips the chase by managing a whole nervous system that wants it badly. Same trade, opposite difficulty. This is the entire reason the discipline has to be trained rather than simply known. You cannot install a rule and assume it holds, because you are not a machine running the rule. You are a primate hosting a committee, and the loudest members were optimized for a savanna, not for an order ticket.

What He Actually Did, and What It Cost

He did not buy the open. Not a starter, not a lottery ticket, nothing. He let the largest IPO in history trade without him, which felt, in the body, like a mistake he would regret for a year. Then he went back to his page. One of his two planned setups triggered an hour later in a name he actually knew, with a level he could point to and a stop he had defined while he was calm. He took it at his normal size, not the size the Dog wanted. It worked, modestly. The other never set up and he left it alone. He finished the day small and green, on a trade he could explain to anyone, having sat out the one move the entire market was talking about.

The cost was real, and worth naming, because pretending it is not is how this kind of advice loses credibility. SPCX printed its high of 176.52 around midday and then gave it back, fading into the close to settle at 160.95, up about 19 percent on its first day but well under where it had traded at the peak. The institutions who got the 135 allocation had a very good day. The people who bought the euphoric push into the 170s, swept up in exactly what Marcus had felt at the open, spent the afternoon in the red on the most exciting stock in the world. Standing aside is not free. It costs you the upside of the thing you stood aside from, every time. The only thing that makes the trade worth it is that it also costs you the disaster, every time, and the disasters are bigger than the upside you miss.

Monday: When the Level Finally Showed Up

Here is the part the Friday chasers never got to, because most of them were already out or already trapped. The story did not end at the close. It got a second day, and the second day is where the lesson pays.

SPCX opened Monday at 171.74, just under Friday's 176 high, the level the whole tape had been arguing about two sessions running. And this time it did the thing Redler's framework actually waits for. It did not reject the level and roll over. It pushed up into Friday's high, reclaimed it, and held above it, and once it was accepted back over that line the supply that had capped it Friday was gone. It ran to a high of 193 and closed at 192.5, another 19 percent on top of Friday's close. The name that had no level on Friday had built one over the weekend, the 176 area, and Monday it told you which side of that line it wanted to be on, clearly, with risk you could define against the line itself.

Read the two days next to each other and the whole point lands. Friday was the open: no level, maximum noise, the Lizard and the Dog at full volume, and a fade that punished everyone who obeyed them. Monday was the setup: a defined level, a clean reclaim, a place to put a stop, and a move that rewarded the patience. The disciplined trader did not miss SPCX. He waited for it to become tradeable, and on Monday it did. Marcus did not catch the Monday move either, it was not one of his setups and a new listing in its first week is still outside his lane, but he watched it reclaim the level and understood exactly why it worked, and that understanding cost him nothing, because he had not spent Friday blowing up his account or his composure on the open.

That is the quiet argument for standing aside. It is not that you are protecting yourself from a loss. It is that you are staying solvent and clear-headed enough to still be in the chair, calm, when the real setup arrives. The trader who chased the Friday open was, by Monday, either nursing a loss or too rattled to act cleanly on the reclaim. The trader who did nothing on Friday got to read Monday with a steady hand. Capital is one thing the chase costs you. Composure is the other, and composure is the one you trade with tomorrow.

The Lesson Under the Story

You will not kill the Lizard. You cannot retire the Dog. They came standard, they kept your ancestors alive, and on most days away from the desk they do useful work. The goal was never a calm brain. The goal is a trained one: a desk arranged so the Professor is still conscious and still has a vote at the moment the order goes in. That is what the plan written the night before actually is. It is the Professor leaving himself a note for the morning, when he knows he will be outnumbered and half asleep. The pre-commitment is not bureaucracy. It is the slow system buying votes in advance, before the fast system shows up and packs the room.

In Trade Calm I give these voices their full roster. Chapter 4, The Twelve Saboteurs, names the specific ones, the Crowd Follower, the Recency Worshipper, the Narrator, and nine others, and every last one of them is a voice of either the Lizard or the Dog. The Professor is the part that calls them by name. The same urge runs under all of it: the urge to make it back, the urge that powers the fear of missing out, the urge to act on the loudest name on the screen. The two-minute pre-trade pause exists for exactly the moment the first print hits and your hand drifts to the mouse.

If you want to meet your own Lizard and your own Dog before they cost you the next IPO morning, the TQ Assessment is built to surface the ones most likely to move you over your next thirty trades. The work of keeping the Professor in the chair under live pressure, breath by breath and rule by rule, is what the Complete Calm Trading Method and Trade Calm teach.

SPCX opened, ran, faded, and then reclaimed its level on the day that actually counted. A year from now most of us will not remember the exact numbers. Marcus will remember that he heard all three voices, called two of them by name, let the quiet one cast the deciding vote, and was still calm enough on Monday to watch the level he had refused to chase do its work without him. On a morning built to make that impossible, that was the whole trade.
