Welcome back to our series on stocks. In the last video, we covered what a stock actually is, how ownership can generate a return, and exactly how to buy your first share. Today, we're covering how to actually read what you're looking at once you own it — the chart, the price, market capitalization, and a company's three core financial statements. This is the video where investing stops being abstract and starts being something you can actually evaluate for yourself.
HOW TO READ A STOCK CHART
Suppose you're looking at Microsoft's stock chart. You'll normally see price on the vertical axis and time on the horizontal axis.
You can change the time period — 1 day, 5 days, 1 month, 6 months, 1 year, 5 years, or longer, depending on the platform. A one-day chart tells you about very short-term price movements, often driven by news, trading activity, or short-term sentiment. A five-year chart gives you a much longer view, one that tends to smooth out daily noise and reveal the broader trend of the business.
You may also see different chart types. A simple line chart just connects the closing prices over time. A more detailed format is a candlestick chart. Each candle can represent a particular period — a day, an hour, a week — and depending on the selected timeframe, a candle can show the opening price, closing price, highest price, and lowest price for that period. A "green" or "hollow" candle typically means the price closed higher than it opened; a "red" or "filled" candle typically means it closed lower. You may also see trading volume displayed as bars underneath the chart, which tells you how many shares were traded during a particular period — a spike in volume alongside a big price move can indicate a significant piece of news or a shift in investor sentiment.
But here's something extremely important, and it's worth repeating throughout this entire series: a chart tells you what the price has done. It doesn't guarantee what the price will do next.
A stock chart going upward doesn't automatically mean you should buy it — you could be buying in after most of the gain has already happened, at a price that no longer reflects good value. A stock chart going downward doesn't automatically mean the business is worthless — it could mean the market overreacted, or it could mean the business is genuinely deteriorating. The chart alone can't tell you which. It needs to be considered alongside the underlying business, its financial information, its valuation, broader market conditions, and your own investment objectives and time horizon.
WHAT DOES THE STOCK PRICE ACTUALLY MEAN?
Suppose Microsoft is trading at $500 per share. What does that $500 actually mean?
It means the market is currently pricing one single share at approximately $500 at this moment. But it does not mean Microsoft as a whole is worth only $500 — the company may have billions of shares outstanding, each one representing a tiny fraction of the total business. That's why we need another concept: market capitalization.
MARKET CAPITALIZATION EXPLAINED
Market capitalization is the approximate total market value of a company's outstanding shares. The basic calculation is:
Share price × shares outstanding = market capitalization
Imagine a company has 100 million shares, and each share trades at $20. Then:
100 million × $20 = $2 billion market capitalization.
This also explains why you cannot determine the size of a company just by looking at its share price. A $20 stock isn't automatically a smaller company than a $200 stock — and this trips up more new investors than almost anything else on this list.
Imagine Company A has 1 billion shares at $20 each:
1 billion × $20 = $20 billion market cap.
Company B has 10 million shares at $200 each:
10 million × $200 = $2 billion market cap.
Company B has the higher share price. But Company A has the larger market capitalization — it's ten times bigger as a business, despite trading at a tenth of the per-share price. The number of shares outstanding matters enormously, which is exactly why serious investors talk about market capitalization when discussing a company's size, and treat the raw share price as almost irrelevant on its own.
Market capitalization also helps you understand risk in a general sense. Companies are often grouped into large-cap (generally the largest, most established companies), mid-cap, and small-cap (generally smaller, often younger or more specialized companies). Smaller companies can sometimes offer more room for growth, but they can also carry more volatility and, in many cases, less financial cushion to survive a downturn — something worth keeping in mind as you start comparing companies of different sizes.
HOW TO RESEARCH A COMPANY BEFORE BUYING
Now we get to one of the most important parts of this entire series.
Before buying a stock, don't start by asking "Is the price going up?" Start with the business itself. Suppose you're researching Amazon (AMZN). Ask:
What does Amazon actually sell? How does it make money — through retail sales, subscription services, cloud computing, advertising, or some combination? Who are its customers, and how loyal or price-sensitive are they? What are its major business segments, and which ones are growing fastest? Is revenue growing year over year? Is the company actually profitable, or is it prioritizing growth over near-term profit? How much debt does it carry, and is that debt manageable relative to its cash flow? How much cash does it generate from its actual operations? Who are its real competitors, and what would it take for one of them to take market share? What could seriously damage the business — new regulation, a shift in consumer behavior, a disruptive competitor? What advantages does the company have that are hard for a competitor to copy? Does it have real, credible opportunities to grow further? And how dependent is it on a single product, a single customer, a single market, or a single piece of technology that could become obsolete?
Then ask the second, equally important question: what am I paying for this business? A great company can still be a poor investment if the price is extremely high relative to the company's financial performance and realistic future prospects. Overpaying for an excellent business is one of the most common — and most avoidable — mistakes new investors make. That's why stock research really has two major components, not one: understanding the business, and understanding the price you're paying for it. Most beginners only ever do the first.
WHERE DO YOU GET INFORMATION ABOUT A COMPANY?
You don't need to rely entirely on social media posts, forum comments, or someone confidently telling you "buy this stock."
Public companies are required, under securities regulation in most major markets, to provide financial and regulatory information you can examine directly. This includes annual reports, quarterly reports, earnings releases, investor presentations, full financial statements, official company filings with the relevant securities regulator, investor-relations websites maintained by the company itself, recorded earnings calls where management discusses results and answers analyst questions, and formal risk disclosures that outline what could go wrong with the business, in the company's own words.
You can also use your broker's built-in research tools and third-party financial-data platforms, many of which pull directly from these official filings and present them in a more digestible format.
But always understand what the information actually represents, and where it's coming from. A social-media post saying "NVIDIA is going to explode" is not the same category of information as examining NVIDIA's actual revenue growth, profit margins, and valuation from its own filings. The first is an opinion, or a prediction, often with no accountability attached. The second is research — verifiable, sourced, and something you can evaluate critically for yourself.
HOW TO READ A COMPANY'S FINANCIAL STATEMENTS
There are three major financial statements every investor should understand, at least at a basic level.
1. The income statement.
The income statement shows the company's financial performance over a specific period — typically a quarter or a full year. You can see revenue (the total money brought in from sales), operating expenses (the costs of running the business), operating income (what's left after operating expenses), interest expense (the cost of any debt), taxes, and finally net income — the "bottom line" profit after everything.
Suppose a company reports $10 billion in revenue, $8 billion in total expenses, and $2 billion in net income. That gives you a snapshot of profitability for that period. But don't stop there — ask: is revenue growing compared to previous periods? Are expenses growing faster than revenue, which would squeeze profitability over time? Are profit margins — the percentage of revenue that turns into profit — increasing or decreasing? Is net income growing consistently, or is it volatile and unpredictable from one period to the next.
2. The balance sheet.
The balance sheet gives you a snapshot — at one specific point in time — of what the company owns and what it owes. You may see assets (cash on hand, inventory, property, equipment, and other things of value the company owns), liabilities (debt owed to lenders, and other obligations the company must eventually pay), and shareholders' equity — roughly, what would be left over for shareholders if the company sold everything it owned and paid off everything it owed.
A company carrying a large amount of debt relative to its cash flow may face very different risks — particularly in a downturn, or if interest rates rise — compared with a company holding substantial cash and relatively little debt. The balance sheet is where you go to understand a company's financial cushion and its ability to weather hard times.
3. The cash-flow statement.
The cash-flow statement shows how actual cash moves through the business over a period — separated into operating cash flow (cash generated from the core business), investing cash flow (cash spent on or received from investments, like new equipment or acquisitions), financing cash flow (cash from or paid to lenders and shareholders, including debt, share buybacks, and dividends), and free cash flow — generally, the cash left over after the business has covered the spending it needs just to maintain and run its operations.
This matters because accounting profit and actual cash generation aren't always the same thing. A company can report a healthy accounting profit on its income statement while its real cash position looks considerably weaker — for example, if it's booked revenue it hasn't actually collected yet, or if profit is being propped up by one-time items. So when researching a company, one of the most important questions you can ask is simply: is this business actually generating real cash, not just reporting profit on paper?
So now you know how to properly read a price chart without mistaking it for a prediction, how to understand what the share price actually represents versus what market capitalization tells you about a company's real size, and how to pull apart a company's three core financial statements to understand whether a business is actually healthy underneath the surface.
In the next video, we're tackling the hardest and most important part of investing: figuring out what a stock is actually worth, understanding dividends and dividend yield properly — including a trap that catches a lot of new investors — and seeing exactly how compounding can turn small, consistent investing into something much larger over time.
