TL;DR: A stock’s price is simply where a buyer and a seller meet. Every tick is shaped by supply and demand, influenced by news, company performance, and the wider economy.

A Price Is a Story, Not Just a Number

That number flashing on your screen isn’t fixed—it’s just the most recent deal between a buyer and a seller. Think of it as a snapshot of the market’s mood at that exact moment. Tomorrow, or even five minutes later, the picture could look completely different.

How a Price Gets Made: Meet the Order Book

Stock prices are born in the order book—the market’s “matchmaking” system:

• Bid: the highest price someone is willing to pay.

• Ask: the lowest price someone is willing to accept.

• Spread: the gap between bid and ask.

• Last price: where the most recent trade happened.

Whenever a bid meets an ask, a trade occurs, and that agreed number becomes the stock’s price. This happens thousands of times a day, constantly shaping the live price you see.

What Pushes Prices Up and Down?

Several forces can nudge stock prices higher or lower:

1. Company results & guidance – Strong earnings attract buyers; warnings about weaker profits often push prices down.

2. News & headlines – Leadership changes, product launches, or scandals can all shift sentiment quickly.

3. Interest rates & inflation – Higher rates make borrowing costlier and bonds more attractive, often cooling demand for stocks. Inflation squeezes profits and consumer spending.

4. Economic & industry trends – Whole sectors can rise or fall together, like tides lifting or lowering all boats.

5. Currency swings – International companies feel stock price effects when exchange rates shift.

6. Liquidity – Popular, heavily traded stocks move smoothly; thinly traded ones can swing sharply even on small trades.

7. Dividends, buybacks, new shares – Dividends attract investors; buybacks reduce supply (lifting prices); issuing new shares increases supply, which can drag prices lower.

8. Investor mood – When optimism (bullishness) rules, buyers dominate. When fear (bearishness) sets in, sellers take control.

9. High-speed trading – Algorithms trading in milliseconds provide liquidity but can amplify sudden price swings.

Price vs. Value: Not the Same Thing

• Price = the current figure at which a trade was made.

• Value = what analysts or investors believe the stock should be worth.

Because opinions constantly shift, price often dances around value. That difference creates opportunities for investors.

Why Expectations Matter More Than Reality

Markets trade on expectations, not just results. Even “good” earnings can send a stock lower if investors expected great. Conversely, a weaker report may push prices up if expectations were even lower.

A Quick Example

• Bid: €9.98

• Ask: €10.00

If someone buys at €10.00, the price moves there. If a big sell order drops and the next best bid is €9.95, the price falls. It’s a constant tug-of-war, creating the ever-moving line you see on a chart.
