In 1997, Amazon went public on the Nasdaq. The company had never turned a profit. It was losing money, competing against established retailers with far more resources, and selling books on the internet at a time when most people were still figuring out what the internet was. By any conventional measure, it looked like a bad bet.
A thousand dollars invested that day is worth over two million dollars today.
So what exactly were investors paying for in 1997? And how does a stock price get set in the first place?
The most common misconception about stock prices is that they reflect what a company is objectively worth, like a price tag on a product in a store.
Instead, a stock price is an agreement. It is the number at which a willing buyer and a willing seller meet at a specific moment in time. The moment that agreement changes, because one side wants something different, the price changes with it.
This means that a stock price is less like a measurement and more like a vote. Millions of investors, every trading day, are casting votes about what they believe a company's future looks like. The price you see on a screen is the current result of all those votes combined.
To understand the mechanics, think about any market where buyers and sellers interact.
When more people want to buy a stock than sell it, sellers are in control. They hold out for a higher price. The price rises. When more people want to sell than buy, buyers have the leverage; they can wait for a lower price, and the price falls. The price at any given moment is simply the point where supply and demand balance out.
This process happens continuously during trading hours. Every time a transaction occurs, it reflects the most current consensus on what that share is worth. Economists call this price discovery: the market's ongoing process of finding the price that clears buyers and sellers.
What makes stock markets unusual is the speed at which this happens. New information can shift that consensus in seconds. Unlike most valued goods, a stock can be repriced thousands of times a day.
If prices reflect consensus about the future, then prices move when that consensus changes.
The most direct trigger is an earnings report. Every quarter, public companies are required to release their financial results. If a company earns more than investors expected, the stock typically rises, not because the company suddenly became more valuable overnight, but because investors update their view of what it will be worth in the future. If it earns less than expected, the stock falls for the same reason.
But earnings are just one input. Interest rates, broader economic conditions, competitor news, regulatory changes, and even investor sentiment can all shift the consensus. In 1997, what moved Amazon's stock wasn't profit — it was the growing belief that Amazon was building something that would eventually be enormously profitable. Investors were not buying what Amazon was. They were buying what they thought Amazon would become.
This is where stock prices start to surprise people.
A company can be profitable and still see its stock fall. If investors expected it to earn more than it did, the result, even if positive, is a disappointment. The stock drops because the future looks slightly less bright than it did yesterday.
Conversely, a company can be losing money and still see its stock rise. If investors believe losses are temporary and growth is inevitable, they will pay a premium today for a share of what they expect tomorrow. This is precisely what happened with Amazon for years. Bezos was reinvesting every dollar back into the business — building warehouses, expanding categories, developing technology — rather than showing a profit. Investors read those losses not as failure but as fuel.
This is why markets are sometimes described as a prediction machine rather than a scoreboard. They are not tallying what has already happened. They are aggregating what millions of people believe is going to happen next.
A stock price is not a verdict on a company's past. It is a collective bet on its future.
That distinction matters because it explains behavior that otherwise seems irrational. It explains why a company with no profits can be worth billions. It explains why a household name can see its stock collapse after a single bad quarter. And it explains why two people looking at the same company can reach completely different conclusions about whether its stock is cheap or expensive, all because they have different views about what the future holds.
Markets are not always right. Consensus can be wrong, sometimes spectacularly so. But understanding that prices are driven by expectations rather than facts is the first step toward making sense of why they move the way they do.
The number on the screen is not the truth. It is everyone's best guess.
