Lesson 4: Behind every stock is a business
Value Investing 101: introductory course
When You Buy a Stock, What Are You Actually Buying?
Many beginner investors see stocks as mere numbers on a screen. Prices go up and down, and the goal seems simple: buy low, sell high. But thinking this way is the wrong approach to investing.
A stock isn’t just a figure in a trading app—it represents ownership in a real company. This is a fundamental insight that completely changes how you view the stock market.
Warren Buffett put it this way:
"If you wouldn't be willing to own a company for ten years, don't even think about owning it for ten minutes."
In other words, investing isn’t a game. When you buy a stock, you become a co-owner of a business. And as an owner, you should want to understand how the company operates, how it makes money, and whether it has long-term potential.
Let’s explore this mindset further.
More Than Just Numbers: Embracing Ownership
Imagine you’re not buying a stock, but a bakery.
You have €250,000 and the opportunity to purchase a small, successful bakery in your neighborhood. How would you approach this decision?
You’d want to know how the bakery makes a profit:
What are the most popular products?
How many loaves of bread and pastries are sold daily?
How much does it cost to pay for ingredients and staff?
You’d examine the financial health of the business:
What has its revenue and profit been in recent years?
Does the bakery have any debt? If so, can it be easily repaid?
Does it have a stable customer base?
You’d look at the competition:
Are there other bakeries nearby?
What makes this bakery unique? Maybe it uses local ingredients or offers a specialty no one else does.
You’d consider the future:
Are there opportunities for growth? Perhaps by opening another location or partnering with local supermarkets.
Are there risks, such as rising ingredient costs or new competitors?
These are the questions you’d ask before buying a real business.
So why don’t most people ask these same questions when buying a stock?
In the stock market, investors often buy companies without understanding how they operate. They buy simply because the stock price is rising, because someone else says it's a good investment, or because it seems like the next big thing.
That’s not investing—that’s gambling.
If you wouldn’t buy a bakery without analyzing the numbers, why would you buy a stock without knowing what the company actually does?
A stock is nothing more than a small piece of a business. If that business thrives, the stock price will naturally rise over time. But if the company is poorly managed, heavily in debt, or unprofitable, its stock price will inevitably fall.
Why This Insight Is Essential
Viewing stocks as ownership in real businesses is crucial for making rational decisions.
✅ You become more selective with your purchases.
You only invest in businesses you understand and find valuable.
You’re less likely to make impulsive trades.
✅ You worry less about short-term price movements.
The stock market is noisy—prices constantly rise and fall.
But if you owned a business, you wouldn’t sell it just because it had a bad month, would you?
✅ You develop a long-term mindset.
A company’s real value is revealed over years, not through daily price fluctuations.
You focus on the business’s fundamental strength, not market hype.
Benjamin Graham, Warren Buffett’s mentor, once said:
"In the short run, the market is a voting machine, but in the long run, it is a weighing machine."
In the short term, stock prices move based on emotions and hype. In the long term, companies with strong fundamentals always prevail.
The Dangers of Thinking in Stock Prices
If you see stocks only as numbers on a screen, you risk making emotional decisions.
Common mistakes of thoughtless investors:
🚨 "The stock price dropped—I’ll sell in panic!"
🚨 "The price went up—I’ll buy more, even if it’s overpriced!"
🚨 "Everyone is buying this stock, so it must be good!"
This is how people get caught in market bubbles. Think of the dot-com crash, the 2008 financial crisis, the hype around meme stocks, or today’s excitement about AI. People bought stocks without analyzing the businesses behind them—and paid the price when the bubble burst.
Warren Buffett once said:
"The stock market is designed to transfer money from the impatient to the patient."
If you understand that stocks represent real businesses, you’ll remain calm when the market moves irrationally.
A Practical Exercise: Viewing Your Stocks as Businesses
Want to test if you truly see stocks as businesses? Try this:
Pick a stock you own or are considering buying.
Write down what the company does, how it makes money, and who its competitors are.
Ask yourself: Would I buy this company as a private business, without knowing the stock price?
If you can’t answer these questions, you don’t know the company well enough to invest in it.
Stocks aren’t abstract numbers. They represent real companies with real revenue, costs, and challenges.
Homework: Analyze Your Portfolio
Look at your investments and describe each company as if you owned it entirely.
By seeing stocks as ownership in businesses, you’ll invest more rationally and with a long-term vision.
