Greed & FOMO

Hook

One Face, Two Screens

Aarav's lunch was going cold, but his eyes weren't on the food. They were on his phone.

The stock he'd bought three months ago had already doubled. Sitting in a small manufacturing office in Pune, he stared at the green number and felt something pull tight in his chest. Sell now and lock in the profit? Or wait — because what if it goes even higher?

"It'll probably touch another twenty percent by Friday," he muttered, more to himself than to Kiran, who was unwrapping a paratha beside him.

He didn't sell. He just kept refreshing.

Ten minutes later, a notification popped up — a completely different stock, one he'd never even owned, was suddenly up eight percent in an hour. Aarav's thumb moved before his brain caught up. His heart did the same thing it had done two minutes ago — that same tight, urgent squeeze, like a rope pulling him forward.

"Buy it now," a voice in his head said. "If you wait, you'll miss it. Everyone else is already in."

He was halfway to opening the buy screen when Kiran, chewing slowly, said, "You're making the same face you made two minutes ago."

Aarav looked up. "What face?"

"That one. Like the phone's about to run away from you." Kiran took another bite, unbothered. "First it was your winning stock — you had that 'don't let go' face. Now it's this new one — 'don't miss it' face. Same face, Aarav."

Aarav almost laughed it off. They felt like completely different problems. One was about a trade he already had — he didn't want to lose the extra gains sitting there waiting. The other was about a trade he'd never touched — he didn't want to lose a chance that was disappearing in front of him.

But he sat there for a second, phone glowing in his hand, thumb hovering over nothing in particular.

Kiran had a point. Both times, it hadn't felt like thinking. It had felt like being pulled.

Aarav set the phone down on the desk, screen up, watching the numbers tick. Not deciding anything yet. Just noticing that his hand had been about to move on both trades — and neither time had he actually stopped to ask himself why.

"Two different problems," he said out loud, testing the words.

Kiran shrugged and reached for his water bottle. "If you say so."

Aarav wasn't so sure anymore.

Learning Objectives

  • Explain how greed can hijack a trading decision even when the trade is already winning — through holding too long or sizing up out of excitement.
  • Recognize FOMO as the same impulse as greed, just triggered by watching someone else's gain instead of your own.
  • Identify urgency — the feeling that you must act right now or lose out forever — as the tell that a feeling, not a plan, is driving a decision.
  • Distinguish between judging a decision by its process versus judging it by its outcome (profit or loss).

Core Concept

In Fear, you learned to catch the moment your Reacting Self grabs the wheel instead of your Observing Self. Greed and FOMO are the same hijack, wearing a different mood.

You already know the feeling of wanting more. You bought a stock, it's up nicely, and some part of you says "don't sell yet — it might go higher." That's greed. It isn't a dirty word here — it's just the plan-independent pull to want more than you originally aimed for. It shows up as holding a winner too long, or suddenly putting in extra money because things are going well.

Now think of the other feeling — watching someone else's stock rip upward on your screen while you're standing outside it, heart racing, thumb already moving toward the buy button. That feels different. It feels like fear, not excitement. That's FOMO — the fear of missing out.

Here's the part that changes how you see both: FOMO isn't a separate emotion you need a separate fix for. It's greed wearing a different costume. Greed gets triggered by your own gain. FOMO gets triggered by someone else's gain. But underneath, it's the exact same impulse — chase more — just lit by a different match.

The urgency itself is the signal to pause — not the signal to act.

You can tell because both feelings produce the identical body signal: a tight, urgent sense that you must act right now, or you'll lose the chance forever. That urgency is the real thing to pay attention to.

The urgency itself is the signal to pause — not the signal to act.

Why does this matter so much? Because a decision made from a plan and a decision made from excitement can look exactly the same from the outside — same buy, same sell, same screen. The only thing that tells them apart is what was actually happening inside you at the moment you clicked. If urgency was driving, a feeling made the decision, not you. And whether that trade later makes money or loses money doesn't tell you which one it was — profit is a scoreboard, not a verdict on whether your judgment held up. A lucky win can hide a decision that was never really yours to begin with.

So the skill this unit is building isn't "stop feeling greedy" or "stop feeling FOMO" — those feelings are normal and won't disappear. The skill is noticing the moment they try to grab the wheel, and asking yourself one honest question: was I choosing this, or was this feeling choosing for me?

Visual Understanding

A gain — yours or someone else's
Urgency: act right now
Pause: was I choosing, or was the feeling?

Same urgency, same fix — notice it, then check for a plan that existed before the feeling did.

Real-life Example

Later that same lunch break, Aarav opens the app again. His winning stock is still climbing. A notification blinks: the new rallying stock is up another 4% in the last twenty minutes.

He notices his hand already moving toward the buy button — before he's thought through a single reason why.

He stops. He turns the phone face-down on the desk and waits out sixty seconds, the way he'd normally check the time on a client call. Then he asks himself the same question, plainly: was he choosing this, or was the feeling choosing for him?

Turning it over, he realizes something uncomfortable. For the new rally, he has no plan at all — no target, no reason he'd looked at this stock before today, nothing except the fear of watching it run without him. And for his winning stock, he actually did have a plan — he'd set a target price for it three weeks ago, calmly, with no notifications flashing and no heart racing. He had been about to ignore his own plan in favor of a feeling that showed up ten minutes ago.

So he sells the winner at the target he'd set weeks earlier. And he leaves the new rally alone — not because it's necessarily a bad stock, but because he has nothing to check it against except excitement.

Same pause. Same question. Two very different trades — but the same fix for both: notice the urgency, then check it against a plan that existed before the feeling showed up.

Point: The same pause-and-ask-DecisionLens move works whether the pull comes from your own winning trade or someone else's rally — the fix isn't a different rule for each feeling, it's noticing the urgency and checking against a plan that was set before the feeling showed up.

Common Mistakes

  • Treating greed and FOMO as two unrelated problems — one about being too hopeful, the other about being anxious — and thinking each needs its own separate fix. — They feel different in the body (one feels like excitement, the other like anxiety) and get triggered by different situations, so they seem like separate issues. Fix: Remember they're the same impulse to chase more — greed is triggered by your own gain, FOMO by someone else's. The fix for both is the same: notice the urgency, then pause.
  • Assuming that feeling strongly — excited or anxious — about a trade is just normal trading energy and has nothing to do with whether the decision is sound. — Confident, successful-looking traders seem to feel things intensely too, so strong feeling gets mistaken for a sign of good instincts rather than a warning. Fix: Treat the intensity of an urge to act right now as a signal to check whether a plan or a feeling is actually making the decision — before acting on it.
  • Believing that a profitable trade made on impulse proves the impulse was trustworthy or that greed/FOMO 'worked' that time. — Outcomes are visible and easy to point to, while the internal process that led to the decision isn't — so a win quietly reinforces whatever behavior came before it. Fix: Judge the decision by what was happening in your head at the moment you acted, not by whether it made money afterward — profit is a scoreboard, not a verdict on your judgment.

Key Takeaways

  • FOMO isn't a separate emotion — it's greed triggered by someone else's gain instead of your own.
  • Both feelings produce the same tell: a tight, urgent sense that you must act right now or lose out forever.
  • That urgency is the signal to pause, not the signal to act.
  • A profitable trade doesn't prove a feeling-driven decision was sound — money is a scoreboard, not a verdict on judgment.
  • The real skill is catching the moment a feeling tries to take the wheel and asking: was I choosing this, or was the feeling choosing for me?

Quiz

Q1. According to this unit, what is FOMO in trading?

  • A completely separate emotion from greed that needs its own fix
  • Greed triggered by watching someone else's gain instead of your own
  • A rational response to a stock's price movement
  • A feeling that only affects new traders Answer: Greed triggered by watching someone else's gain instead of your own — FOMO isn't a new emotion to learn — it's greed wearing a different costume, triggered by someone else's gain rather than your own.

Q2. True or False: Feeling a strong urge to act immediately on a trade is just normal trading energy and has nothing to do with whether the decision is sound. Answer: False — The intensity of an urge to act 'right now' is actually a signal that a feeling, not a plan, may be driving the decision — it's a cue to pause, not to ignore.

Q3. A trader buys a stock on a sudden impulse during a rally, with no plan behind it, and ends up making a profit. What does this profit actually tell us?

  • It proves the impulse was trustworthy and can be followed again
  • It proves the trader has good instincts for spotting rallies
  • It's just a scoreboard result — it doesn't prove the decision process was sound
  • It means greed and FOMO don't apply to profitable trades Answer: It's just a scoreboard result — it doesn't prove the decision process was sound — Profit or loss is a scoreboard for the outcome, not a verdict on whether the judgment behind the decision was sound. A lucky win can hide a broken process.

Q4. A stock someone has never researched jumps 8% in an hour. They buy immediately, thinking: "I'll research it after, I can't miss this move." Is buying first and researching later a sound response to this feeling? Reveal: Weak: yes, speed matters more than research when a stock is moving fast. Strong: the urgent, must-act-now feeling is the exact tell that a feeling, not a plan, is making the decision — the skill is pausing to check if a plan exists before acting, not confirming the plan afterward.

Curiosity Bridge

Notice this: the feeling doesn't announce itself as greed or fear — it just shows up as urgency, wearing whatever costume the moment hands it. The quieter you get around that feeling, the more clearly you'll start seeing which other ones have been driving your hand all along.

This week, try: The next time you feel that must-act-now pull on a trade, stop for sixty seconds and say out loud: 'Am I choosing this, or is this feeling choosing for me?' (Set your phone face-down for those sixty seconds before you touch any buy or sell button — let that one small motion be your signal to actually pause instead of just intending to.)

Think of the last time you saw a stock, crypto, or deal 'running away' without you — did you feel pulled to jump in immediately? Did you pause before acting, or act first and think later?

It is remarkable how much long-term advantage people like us have gotten by trying to be consistently not stupid, instead of trying to be very intelligent.
