What is a stock price? Why do stock prices go up and down? And does a lower stock price mean a company is cheaper?

In this video, we explain stock prices in simple terms for beginners learning about the U.S. stock market.

Stock Price Example

Suppose a fictional company, ABC Technologies, has a stock price of $50 per share.

1 share = $50
10 shares = $500
20 shares = $1,000

Formula:

Total Share Purchase Cost = Number of Shares × Price Per Share

These figures are hypothetical examples for educational purposes and do not represent actual market prices.

Stock Price vs. Market Capitalization

Stock price tells you the price of one share.

Market capitalization estimates the total market value of a company's outstanding shares.

Formula:

Market Capitalization = Share Price × Shares Outstanding

A stock trading at $10 is not necessarily cheaper than a stock trading at $100. The number of outstanding shares and the company's financial performance and valuation also matter.

Why Do Stock Prices Change?

Stock prices can change because of:

- Supply and demand
- Company earnings
- Future growth expectations
- Economic conditions
- Interest rates and inflation
- Company news and announcements
- Investor expectations and sentiment

A price increase does not automatically mean a company's business has improved, and a price decline does not always mean its business has deteriorated.

00:00Welcome back to today's explainer.
00:02You know, we spend so much time obsessing over complex charts, earnings calls, and major macro trends
00:07that it's actually really easy to overlook the absolute foundation of it all, the stock price itself.
00:13So today, we're going to strip away all that noise.
00:16We're going right down to the mechanical bedrock of the market
00:19to figure out exactly what that ticker price represents and honestly what it doesn't.
00:24Let's dive right in with a psychological trap that catches almost everyone at some point.
00:28Does a lower price tag automatically mean you're getting a cheaper valuation?
00:33We are totally hardwired from the grocery store to think a $10 item is obviously cheaper than a $100 one,
00:38right?
00:39But the stock market plays by a completely different set of rules.
00:42Assuming a low-priced stock is a bargain is literally one of the biggest financial illusions out there.
00:49So here's our roadmap for today.
00:51We're going to deconstruct the price tag, figure out how to properly read the screen data,
00:55explore why these prices actually move, completely shatter that cheap stock myth,
01:01and finally, look at the real-world mechanics of your own portfolio.
01:05All right, part one, the price tag.
01:07Let's start with the absolute simplest building block we have.
01:11Imagine you pull out your phone, you look up a massive tech giant like Apple,
01:15and you see a nice, round, fictional price tag of exactly $200.
01:20That simply means at that exact millisecond in time,
01:23the going rate to buy one single slice of that company's equity is $200.
01:27But keep in mind, that price on your screen, it isn't a locked-in contract.
01:32Depending on market volatility and the specific type of order you place,
01:35your actual execution price could absolutely shift before the trade goes through.
01:40The math here is beautifully simple.
01:42You just multiply the number of shares you want by that per share price.
01:45So five shares at $200 puts your baseline cost at a cool $1,000.
01:50Just don't forget to factor in any lingering brokerage fees or commissions
01:54that your specific platform might tack on.
01:56Reading the screen.
01:58Because knowing the price is great, but without context,
02:00it doesn't really tell you a whole lot.
02:02Consider a totally made-up company.
02:05Let's call it ABC Technologies, trading under the ticker ABCT at $50.
02:09Seeing $50 in a vacuum is pretty useless.
02:12The real vital context comes from the daily change, which is up $2 here,
02:17and the percentage change, sitting at a positive 4%.
02:20This tells you the momentum of the stock right now relative to its baseline,
02:24which is almost always where it finished up during the previous session's closing bell.
02:28But as we all know, that price is never just standing still.
02:32During regular U.S. trading hours, so 9.30 a.m. to 4 p.m. Eastern Time,
02:36the price is constantly fluctuating.
02:38It might open the day at $50, bump up to $52 while you're eating lunch,
02:42dip a bit in the afternoon, and finally settle at $53 when the closing bell rings.
02:46And tomorrow, the whole shebang starts all over again,
02:50often kicking off at a completely different number thanks to pre-market or after-hours trading.
02:54Why on earth isn't the price just standing still?
02:58What are the invisible hands actually pushing that number around all day?
03:02Well, it's a real-time collision of quite a few forces.
03:05You've got the hard fundamental data, like company earnings and future expectations.
03:10Then you have those big macroeconomic wins, right?
03:13Things like inflation, economic conditions, or unexpected global news.
03:17But ultimately, all of this data gets filtered through human psychology.
03:21General investor sentiment, fear, and greed dictate the supply and demand at any given second.
03:27So a falling price doesn't always mean a failing business.
03:30A lot of the time, it just means expectations are shifting.
03:32And that brings us to part four, the absolute core of our analysis today,
03:37where we finally bust that massive myth.
03:40Imagine a scenario comparing two businesses.
03:43Company A trades at just $10 a share.
03:45Company B trades at a hefty $100.
03:48At a quick glance, company A looks like an absolute steal, right?
03:52But hold on.
03:53Look at the total shares outstanding.
03:55Company A has sliced its equity into 1 billion tiny pieces,
03:59while company B has only issued $100 million.
04:02When you actually do the math,
04:04the market is valuing both of these companies at the exact same $10 billion.
04:09Market capitalization.
04:10By multiplying the share price by the total shares outstanding,
04:14you get the true, actual size of the company.
04:16You simply cannot gauge valuation from a single share price
04:20without knowing how many shares exist in total.
04:22Just remember, market cap isn't a pile of cash sitting in a corporate vault somewhere.
04:26It's simply the market's current, real-time consensus
04:29on what the entire operation is worth.
04:32Finally, let's wrap up with part five, mechanics and reality.
04:36How do these corporate actions and price changes actually impact your wallet?
04:40You will constantly hear news about dramatic stock splits,
04:43and it can sound a bit like magic money.
04:46But honestly, it's exactly like ordering a pizza.
04:49Say you own 10 shares at $100.
04:51You have a $1,000 investment.
04:53If the company executes a two-for-one split,
04:56they aren't baking you a second pizza.
04:58They're literally just cutting yours into more slices.
05:00You now hold 20 shares.
05:02The price instantly halves to $50.
05:04But your total investment?
05:05It is still exactly $1,000.
05:08The share count changes,
05:09but your slice of the overall pie is exactly the same.
05:12It is absolutely crucial to understand the difference
05:15between the numbers flashing on your screen and concrete reality.
05:19If you buy 10 shares at $50,
05:21your cost is $500.
05:23If the price rises to $60,
05:25your app is going to show a value of $600,
05:27giving you a $100 gain.
05:29But listen to me on this.
05:30This is an unrealized gain.
05:33If the price suddenly plummets to $40,
05:35you now have a $100 unrealized loss.
05:38The point here is that these gains and losses only exist on paper.
05:42They do not become a financial reality
05:44until you actually click that sell button.
05:47And even then,
05:48your real-world outcome is going to be impacted by taxes and fees.
05:51So you now know how to read the tape,
05:54how to calculate market cap,
05:55and how to separate screen illusions from your actual wealth.
05:58But this leaves us with a truly fascinating psychological puzzle to think about.
06:02If price is really just an ongoing agreement between buyers and sellers,
06:06what exactly is happening in the collective mind of the market
06:09to make them agree on completely different prices,
06:11literally second by second?
06:13We'll be tackling that intricate psychology of supply and demand in our next explainer.
06:17Until then, keep looking beyond the price tag.
