RuleZero Playbook — Part 4

What do I need to know before I click buy?

The research is done. The industry has a real tailwind, the company has a real moat, and the price leaves room to be wrong. Most people click buy right here. I think there's one more step, and skipping it is why good analysis still turns into bad ownership.

Before I buy anything, I write the thesis down. Not the spreadsheet, just a few plain sentences: why this business wins, what has to stay true, and what I expect to happen if it does. If I can't write it that simply, I don't understand it yet. I'm not buying a company, I'm buying a story someone else told me.

Then comes the harder part. I write down what would break it. Every thesis rests on a few assumptions that carry all the weight, and I want to name them while I can still think clearly. Because the moment money is on the line, my brain changes jobs. It stops being an analyst and becomes a defense lawyer.

Once you own a stock, every new fact becomes a threat or a relief. Never just a fact.

That's also why I decide in advance how I'll behave when the price falls. Not if. When. Somewhere in the next decade this stock will drop hard, and the only plan I'll trust in that moment is the one written before I owned anything. If I haven't decided what a 30 percent drop means ahead of time, the market will decide for me, and its answer is always sell.

The order takes one second. Everything that makes it a good order happens before.

Why did $SPCX just fall through $4.3 billion of guaranteed buying?

One week ago, SpaceX joined the Nasdaq-100. Index funds had no choice but to buy an estimated $4.3B of the stock. That was the largest scheduled buy order in the company’s short public life. Known date, known size, demand driven by rules instead of opinion.

The stock fell the day it joined. It hit an all-time low the day after. Then it kept falling.

• IPO price (June 12): $135
• Peak (June 16): $225.64
• Latest close (July 14): $136.08
• Drawdown from peak: ~40%, in one month

Nothing that changed inside the business explains this. No new rocket failure, no lost contract, no bad quarter. Starlink still generates operating profit, and SpaceX still launches more than every national program combined.

The explanation is simpler and more uncomfortable. When SpaceX went public, less than 5% of the company was actually available to trade.

That scarcity is what built the $225 price. Retail money, thematic ETFs, and index funds all chased a tiny pool of shares. The price wasn’t measuring what SpaceX is worth. It was measuring how little of it you could buy.

Now the same math is running in reverse. The lockup calendar starts opening after the first earnings report in a few weeks. One strategist at 22V Research estimates insiders could be free to sell up to 44% of the company by early September, expanding the tradable supply roughly ninefold.

Here’s the part that matters. When an estimated $4.3 billion of forced demand arrives on schedule and the stock still makes new lows, sentiment isn’t setting the price. Supply is. Sellers are simply bigger than the bid.

So the real question for anyone watching this dip isn’t whether SpaceX is a great company. It clearly is.

The question is which price was ever real. $225 was the price when almost nobody was allowed to sell. Over the next two months, the market finds out what SpaceX costs when almost everybody can.

That’s not a crash. That’s price discovery, arriving on a schedule everyone could have read in the prospectus.

RuleZero Playbook — Part 2

Which company inside that industry deserves my money?

Finding the right industry is only half the work. A sector on the rise pulls in capital, talent, and competitors all at once. The tailwind is shared by everyone in the sector, but the returns are not.

When the money floods in, dozens of companies chase the same opportunity. Most of them spend years fighting for the same customers, competing on price, and watching their margins get thinner. Only a few build something that lets them keep a disproportionate share of what the industry creates.

A rising tide lifts the industry. It doesn’t hand you the winner.

So the question isn’t which company is growing fastest. Fast growth inside a strong sector is common, and it’s often borrowed from the tailwind rather than earned. The question I care about is which company can defend what it builds.

This is the part most people skip. An industry can create enormous value and still leave almost none of it on the table for the companies inside it. Think of how much semiconductors have reshaped the world over the past two decades, and how few of the firms that made it happen actually kept the reward. The value a sector creates and the value a single company captures are two very different numbers.

What decides the gap between them is a durable advantage. Some companies grow only because the whole sector is growing, and the moment competition sharpens, that growth quietly disappears. Others own something rivals can’t easily copy: a network that gets stronger as it scales, a cost structure no one can match, switching costs that keep customers in place, a brand people reach for without thinking. That advantage is what lets a company convert the industry’s success into its own.

I also want to know how the business makes money, and what management does with the profit once it arrives. A company can lead its market and still destroy value if it reinvests badly or buys growth that never covers its cost of capital. The best businesses don’t just win once. They widen the gap year after year.

In the best industries, the value created and the value captured are rarely the same thing. The moat is what turns one into the other.

@RuleZeroInv How do you separate the real clues from just temporary hype?

RuleZero Playbook — Part 1

Which industries will define the next decade?

Most investors start by looking for stocks. They screen for companies with strong financials, compare valuations, and try to figure out which business will outperform over the next few years. I think that’s starting one step too late.

Before I spend time researching a company, I want to understand the industry it operates in. Every business competes within an environment it doesn’t control. When an industry is growing, great companies have more room to expand. When an industry is shrinking, even great companies have to work much harder just to maintain growth.

Companies don’t grow in isolation. They grow within industries.

Investing is ultimately a bet on the future. When you buy a stock, you’re also making an assumption about how the world will change over the next decade. If that assumption is wrong, choosing the best company inside the wrong industry rarely leads to exceptional long-term returns. But if you identify the right long-term tailwinds, your odds of finding extraordinary businesses improve dramatically.

That’s why I don’t start by asking which company will win. I start by asking which industries are most likely to create the biggest opportunities over the next decade. Only after I have that answer do I begin looking for the companies that deserve my capital.

The industry determines the opportunity. The company determines who captures it.

Why did the market fall today… and then recover?

Most people think the market needs one reason to go up or down.

It doesn’t.

Early in the session, investors reacted to a combination of earnings news and renewed questions around the AI investment cycle. Expectations were reset, and semiconductor stocks sold off across the board.

But as prices fell, another group of investors started asking a different question.

Has the long-term thesis actually changed?

Samsung’s earnings weren’t disastrous.

They just weren’t enough to raise expectations further.

The AI story was still intact.

For many investors, the fundamentals looked far more stable than the price action suggested.

So buyers stepped in.

Not because everyone suddenly became bullish.

But because they saw value at a price others were willing to sell.

Markets don’t recover because everyone changes their mind.

They recover because buyers and sellers finally agree on a new price.

A month after becoming a public company, $SPCX (SpaceX) reached another major milestone.

Today, SpaceX is set to join the Nasdaq-100.

Many investors may see this as just another step for a large company. But there is something more interesting happening beneath the surface.

When a company grows large enough, it doesn’t just attract investors who want to buy its stock. It can become a company that the investment system is built to own.

Passive funds don’t buy SpaceX because they believe in Elon Musk, or because they are making a prediction about its future.

They buy it because tracking the index requires them to.

Most companies spend years searching for capital. But the greatest companies eventually become destinations where capital naturally flows.

That is the difference between a good company and a truly dominant one.

SpaceX joining the Nasdaq-100 is not just about entering an index. It is another sign that the company is moving into a different stage.

From a company investors choose to buy,
to a company the investment system is built to own.

RuleZero was never six rules. It was one sequence.

Rule #0: builds your foundation, so a bad month never forces your hand.

Rule #1: builds your reason for holding, so a headline can’t do what your own thesis hasn’t done.

Rule #2: builds your process, so you stop re-deciding the same trade every time the market moves.

Rule #3: builds your timeframe, so a quiet quarter stops looking like a broken thesis.

Rule #4: builds conviction that holds, so new information sharpens your thesis instead of replacing it.

Rule #5: makes sure everything you’ve built survives when it’s finally tested.

Six rules. Six predictable ways investors get in their own way. Each one exists to prevent a mistake before it becomes irreversible.

Look at the order. It isn’t random.

You can’t protect your thesis before you have one.

You can’t follow a process before you know why you’re holding.

You can’t protect your psychology before you’ve built something worth protecting.

Each rule exists to make the next one possible. Skip one, and the ones after it become harder to keep.

That’s why RuleZero was never about finding better investments. It was about becoming the kind of investor who can hold them.

One of the biggest investing lessons from the first half of 2026:

Broadcom reminded investors that great businesses and great stocks are not always the same thing.

The company delivered another strong quarter.

But the stock still fell.

Not because the business disappointed.

But because expectations were even higher.

The market doesn’t reward great companies.

It rewards companies that exceed expectations.

Understanding the business isn’t enough.

You also have to understand what’s already priced in.

Jeremy Grantham says AI is a bubble.

He might be right.

But does a bubble automatically mean it’s a bad investment environment?

Not necessarily.

The dot-com bubble wiped out most of the companies people were excited about.

But Amazon survived.
Microsoft kept compounding.
The internet didn’t go anywhere.

What collapsed was the price of the hype.

What survived was the value of great businesses.

So if AI is in a bubble today, I’m not asking:

“Should I avoid AI?”

I’m asking:

“Which of these companies will still matter in 10 years?”

Bubbles don’t kill technology.

They expose businesses that were never worth their valuations in the first place.

The hard part isn’t spotting the bubble.

It’s knowing who’s still standing after it bursts.
