Why Smart People Make Terrible Equity Analysts
Being smart is useful for equity research. It’s just not as useful as people think.

I once interviewed a candidate who checked every box on paper. Top-tier MBA, Ivy League undergrad, two years at a bulge bracket. Could build models in his sleep.
I asked him a simple question: "Why would you buy Costco at 35x earnings when Walmart trades at 22x?"
He spent twelve minutes walking through a DCF comparing ROIC trajectories, explaining the NPV of the membership model, building a framework for retailer quality based on inventory turns and operating leverage. It was technically perfect. It was also completely wrong.
The actual answer is simpler: Costco creates more value for customers than Walmart does, and that value is durable. You can see this by shopping at both stores. The math is just dressing on top of that insight.
He never got past the first round. This happens more than you'd think. The correlation between raw intelligence and investing success is weaker than people assume. Sometimes it's inverse.
The Problem With Being Smart
Smart people are good at building frameworks. That's how they succeeded in school, consulting, banking. Take a messy problem, structure it, fill in the boxes, arrive at an answer. This works great for problems with defined parameters. It's a disaster for investing.
Investing isn't about processing information faster. It's about seeing what matters when most of the information is noise. Really smart people struggle with this because they're trained to process everything, not ignore most of it.
I've watched brilliant analysts build elaborate models with 17 sensitivity tables and five-year projections down to the quarterly level. They can tell you what happens to free cash flow if gross margins expand 30 basis points. But they can't tell you if the company has a sustainable competitive advantage. They can't explain why customers would keep buying in five years. They've optimized the wrong skill.
Pattern Matching Instead of Thinking
Here's what happens: smart people get good at pattern matching. They see something that looks familiar and apply the same framework.
A candidate once pitched me a SaaS company. He obviously read the SaaS playbook, talked about Rule of 40, net dollar retention, payback periods, all the standard metrics. The framework was perfect. But the company wasn't actually like other SaaS businesses. Their customers were small restaurants with 15% annual churn. They weren't accumulating accounts that stuck around for a decade. The SaaS pattern didn't apply. He'd learned the pattern so well he forced the company into it.
Less smart analysts sometimes do better because they're forced to think from first principles. They can't just apply a framework. They have to understand the business.
What does this company do? Who pays them? Why? Will they keep paying? Is anyone else going to do this better? These are simple questions. You don't need to be brilliant to answer them. You need to think clearly.
The Interesting Idea Problem
Smart people are drawn to interesting ideas. Makes sense. Interesting is what got them recognition in school. The interesting answer on the exam, the interesting thesis, the interesting case solution. Investing doesn't care about interesting. It cares about right.
I see this in every interview cycle. Candidates pitch these elaborate theses with multiple layers and second-order effects and contrarian takes. They're intellectually impressive. They're often wrong.
The best investments I've made were boring. A company that did the same thing for 20 years and kept getting better at it. A business model that was obviously good but slightly misunderstood. Nothing clever. Just sound.
Smart people struggle with boring. They want the hidden insight, the thing nobody else sees. Sometimes there isn't one. Sometimes the insight is just "this is a good company at a reasonable price." That's not satisfying if you're used to being the person with the clever answer.
When Models Become a Liability
Really quantitative people—math majors, physics PhDs, engineers—often struggle as equity analysts. Not always, but often enough that I notice.
The problem is they're trained to trust models. In physics or engineering, if your model is good and your inputs are right, you get the right answer. The universe follows rules. Companies don't. People don't. Markets really don't.
I've seen quant analysts build beautiful models that are garbage in, garbage out. They'll spend days perfecting the model structure while barely thinking about whether their revenue growth assumption makes sense. The model feels rigorous, so they trust it.
Less quantitative analysts know their models are rough guides. They spend more time thinking about whether assumptions are reasonable and less time perfecting the math. Often, they're more right.
The Ex-Consultant Problem
Former consultants are particularly tough. Whip-smart, incredibly hardworking, great at frameworks. They interview really well. They often struggle when they start.
Consulting rewards looking comprehensive and structured. You build a deck with a clear framework, do analysis, present authoritatively. The format matters as much as the content because you're selling to a client. Investing is different. Nobody cares about your framework. They care if you're right. The market isn't a client you need to convince. It's a reality you need to understand.
Ex-consultants also think in terms of strategic initiatives and turnaround plans. They pitch stocks based on what management could do to fix the business. That's not useless. But it's not how you make money. You make money understanding what's actually happening, not what could theoretically happen if management executes perfectly.
The candidates who do best often aren't the ones with the best credentials. They're the ones who spend time understanding what customers actually value, not what the company says they value. Who think about whether the business makes sense, not whether the strategy deck looks good.
Speed VS. Depth
Smart people are fast thinkers. In most contexts, that's good. In investing, it's often a problem.
When you're really smart, you can quickly build a thesis that sounds right. You connect dots fast, see patterns, make logical leaps. This feels productive. Sometimes it is. Often it's just fast, not deep.
I've done this myself. I'll meet with a company and within 20 minutes I've got a thesis. It's coherent. It fits together. It sounds smart. Then I sit with it for a few days and realize I don't actually understand the business. I just built a story quickly.
There's an optimal thinking speed for investing, and it's slower than most smart people naturally operate. You need time to be confused, to not understand something, to let a question sit. Fast thinkers blow through that phase before they get the benefit from it.
The Humility Gap
This might be the biggest issue. Really smart people spent their whole lives being right. They got praised for having the answer. They built an identity around being the smart person in the room.
Investing punishes that mindset. You're going to be wrong constantly. The market doesn't care about your GPA. It's going to humble you regularly.
People who are used to being wrong handle this better. They already know what it feels like to not have the answer. They're comfortable with uncertainty. They don't need to defend every position because being wrong doesn't threaten their identity.
I've watched brilliant analysts struggle because they can't admit when they're wrong. They'll defend a bad position because reversing feels like intellectual failure. They can't say "I don't know" in meetings because they're supposed to be the smart one.
What Actually Predicts Success
The best analysts I've worked with aren't usually the smartest by standard measures. They combine moderate intelligence with better traits.
They're genuinely curious about how things work. Not intellectually curious in an abstract way. Actually, curious about why companies succeed or fail, what customers value, how industries evolve.
They're comfortable with uncertainty. They can hold multiple views without needing to resolve them immediately. They can say "I don't know" without it being painful.
They think in terms of what matters, not what's measurable. They focus on the handful of variables that drive value rather than building comprehensive models of everything.
They're skeptical of their own intelligence. They know being smart doesn't make you right. They check their work. They look for disconfirming evidence.
They're patient. They can sit with a question for days without needing to resolve it. They don't need the dopamine hit of having the clever answer quickly.
What I Look for When Hiring
If I'm hiring an analyst, here's what predicts success better than intelligence.
Have they been wrong about something important? I want evidence of intellectual humility. Can they talk about a time they were completely wrong and what they learned? Smart people often haven't had this experience, or they've reframed every failure as not really their fault.
Can they explain something complex simply? If you can't explain your thesis to someone outside finance, you probably don't understand it. Smart people hide behind complexity. Good analysts make things clearer.
Are they interested in mundane details? The best analysts care about boring things like how customers actually use a product or what the sales process looks like. Smart people want to talk about strategy and disruption.
Do they change their mind? I'll push back on something they said and see what happens. People who update based on good arguments are trainable. People who defend their initial position no matter what aren't.
Can they sit in silence? I'll ask a hard question and wait. Smart people rush to fill silence with an answer. Good investors sit with the question and think.
When Smart People Succeed
Smart people can be great analysts. But they need to unlearn things first.
They need to get comfortable being wrong publicly. They need to stop optimizing for sounding smart and start optimizing for being right. They need to value simple and clear over complex and impressive.
They need to slow down. Build in friction. Question their quick answers. Spend time being genuinely confused instead of jumping to a framework.
Most importantly, they need to stop trusting their intelligence as the main input. Intelligence is useful, but it's like having a fast car. It only helps if you're going in the right direction. If you're headed the wrong way, speed makes it worse.
The smartest analysts I know are suspicious of their own cleverness. They know their brain is good at building convincing narratives. They know frameworks can be wrong. They know fast answers are often shallow answers.
They've learned to combine intelligence with skepticism, speed with patience, confidence with humility. That's rare. Most smart people never get there because they succeeded for too long without needing those traits.
What This Means If You're Preparing For Interviews
If you're really smart and want to break into equity research, here's what matters.
Practice being wrong. Deliberately take positions you're uncertain about and track them. Get comfortable with not knowing. Notice when you're defending a position because you said it, not because you believe it.
Slow down your thinking. When you have a fast take, force yourself to wait a day before writing it down. See if it still feels right. Often it won't.
Focus on simple questions. Before you build the model, answer: What does this company do? Who pays them? Why? Will they keep paying? Is someone going to do this better? If you can't answer these simply, the model doesn't matter.
Hunt for disconfirming evidence. Your brain is good at finding evidence that supports what you already think. Deliberately look for reasons you're wrong. How would you short this if you had to?
Talk to people who aren't like you. Smart people talk to other smart people who think in similar ways. Force yourself to learn from operators, customers, regular employees. They see things you miss.
The Bottom Line
Being smart is useful for equity research. It's just not as useful as people think, and it comes with liabilities that aren't obvious.
The smartest candidates often make the worst investors because they pattern match instead of thinking from first principles, optimize for interesting instead of right, trust their models too much, need to be right to maintain their identity, and think too fast to really understand things.
The best investors combine enough intelligence to understand complex businesses with the humility to know they'll be wrong often, the patience to really understand what matters, and the discipline to focus on simple truths instead of clever frameworks.
If you're smart and you know it, that's both your edge and your liability. The question is whether you can unlearn the habits that made you successful in school and build the ones that actually work for investing. Most can't. The ones who can often become exceptional.
