Core Concept

A stock price is not a fact stamped on the company. It is just the newest point where one buyer and one seller happened to agree.

Think about a vegetable seller with a basket of tomatoes. One shopper thinks 40 rupees a kilo is fair and pays it. Ten minutes later, another shopper thinks that's too much and only agrees at 38. Nothing about the tomatoes changed. Two different people simply valued them differently, based on how much they wanted them right then. A stock works the same way, except thousands of people are forming an opinion on it at once, all the time.

The price moves because people keep re-deciding what something is worth to them.

At any second, some people watching a stock think it's worth more than its last price and are ready to buy. Others think it's worth less and are ready to sell. When one buyer's number and one seller's number happen to match, a trade happens, and that becomes the new price. Everyone else who disagreed is still out there, holding their own number, waiting.

This is why the price never sits still. It isn't drifting randomly, and no single hand is pushing it. A market that never moved would actually be the strange one, because it would mean everyone had stopped changing their minds.

So when you see a price tick up or down, don't read it as good news or bad news by itself. Ask what changed: is there a real reason enough people are re-valuing this, or did one buyer and one seller just meet at a slightly different number this time? That question is worth more than reacting to the tick.

Visual Understanding

₹484

this trade

₹482

a minute later

A different buyer and seller found their own point of agreement; the ticker just kept score.

Real-life Example

A different stock trades at 610 rupees, the price two traders last agreed on.
One buyer offers 608 rupees, another is ready to pay 613, and the seller picks the 613 rupee buyer first.
The next sale settles at 610 rupees again, since a different buyer and the seller agreed there.

Go deeper: Deep Dive

Each tick you see is only the record of one pair, one buyer and one seller, agreeing at that instant. It says nothing about what everyone else watching the stock currently thinks. Thousands of people might still believe the stock is worth more, or less, than that last agreed number, and their opinions simply haven't turned into a trade yet. The price line you see is a trail of separate agreements, not a running vote of the whole crowd.

Go deeper: Common Mistakes

Treating a falling price as bad news and a rising price as good news by itself. Apps show red for down and green for up, and everyday language already treats up as good and down as bad. Fix: Ask what actually changed in people's thinking before deciding the move means anything about the company.
Assuming there is one true or correct price and the market is searching for it. Shop price tags are fixed, so it feels natural to expect stocks to have one right value too. Fix: Remember different people can honestly value the same stock differently at the same time, and the price is just wherever the latest pair agreed.
