Fundamental analysis is the practice of valuing a company by looking at the business behind the stock: what it sells, what it earns, what it owes, and what it is likely to earn in future. Investors use it to decide what to own. Traders use it to understand why a stock is moving and what might move it next. This guide gives you enough to read a company's numbers without a finance background.
Key takeaways
- Every public company publishes three core statements: the income statement (profit), the balance sheet (what it owns and owes), and the cash flow statement (actual cash in and out).
- Ratios such as P/E, P/S, and debt-to-equity make companies comparable. They mean little in isolation and a lot against peers and history.
- Stocks move on the gap between results and expectations, not on results alone. "Good" earnings can sink a stock that was priced for "great."
- Fundamental analysis tells you what a company might be worth. It does not tell you when the market will agree.
What fundamental analysis is
Fundamental analysis tries to estimate a company's intrinsic value, what the business is actually worth based on its earnings, assets, growth, and risks, and then compares that estimate with the current share price. If the price is well below the estimate, the stock may be undervalued; well above, overvalued. The approach is the backbone of long-term investing and of the "catalyst" trades that swing and position traders build around earnings reports.
It has two halves. Quantitative analysis works with the numbers in financial statements. Qualitative analysis judges things numbers cannot capture: the strength of a brand, the quality of management, the competitive landscape. Both matter; the numbers are just easier to teach.
Where the numbers come from
In the United States, public companies must file audited reports with the Securities and Exchange Commission: an annual report (Form 10-K) and quarterly reports (Form 10-Q). Companies also publish a press release and host a conference call on the day they report earnings, and their investor relations website collects all of it. Listed companies in other countries file equivalent reports with their own regulators and exchanges.
Your broker's platform and free finance sites summarize the key figures and ratios, which is enough for a first pass. For anything you intend to hold for a while, read the actual report, at least the sections on business overview, risk factors, and management's discussion of results.
The income statement: is the company profitable?
The income statement shows what the company earned and spent over a period (a quarter or a year). Read it top to bottom:
- Revenue (sales, the "top line"): total money brought in from customers. Growth in revenue is the first thing most analysts look at.
- Gross profit: revenue minus the direct cost of producing what was sold. Gross margin (gross profit ÷ revenue) shows pricing power; software companies often have gross margins above 70%, grocers below 30%.
- Operating income: gross profit minus operating expenses such as salaries, rent, research, and marketing. This is the profit from running the business itself.
- Net income (the "bottom line"): what is left after interest and taxes. It can be distorted by one-off items, so compare several periods.
- Earnings per share (EPS): net income divided by the number of shares outstanding. EPS is the figure most quoted in earnings headlines, and the denominator of the P/E ratio.
The balance sheet: what it owns and owes
The balance sheet is a snapshot on a single date of the company's assets (cash, inventory, equipment, buildings, intangibles), its liabilities (debt, bills owed, deferred obligations), and shareholders' equity, which is assets minus liabilities. Key questions:
- How much debt is there, and can it be serviced? High debt magnifies both good and bad years and can become fatal when interest rates rise or sales fall.
- How much cash is on hand? Cash is a cushion against bad times and fuel for growth or buybacks.
- Is equity growing? Rising book value over years suggests the company is retaining and compounding profits.
The cash flow statement: is the profit real?
Accounting profit and cash are different things. A company can report net income while burning cash (because customers have not paid yet, or because it is spending heavily on equipment), or report a loss while generating plenty of cash (because of non-cash charges like depreciation). The cash flow statement reconciles the two. The number most analysts care about is free cash flow: cash generated by operations minus capital expenditures. It is the cash a company could pay out to shareholders without harming the business, and it is harder to manipulate than earnings.
Key ratios and what they mean
| Ratio | Formula | What it tells you |
|---|---|---|
| Price-to-earnings (P/E) | Share price ÷ EPS | How many years of current earnings you are paying for. Higher means the market expects more growth, or the stock is expensive. |
| Forward P/E | Share price ÷ next year's expected EPS | Same idea, using analysts' forecasts instead of past results. |
| Price-to-sales (P/S) | Market cap ÷ revenue | Useful for companies with no profits yet. Still, revenue without a path to profit is a warning. |
| Price-to-book (P/B) | Share price ÷ book value per share | Price relative to net assets. Most relevant for banks and asset-heavy businesses. |
| EV/EBITDA | Enterprise value ÷ earnings before interest, tax, depreciation and amortization | Valuation that accounts for debt, so highly indebted companies cannot hide behind a low P/E. |
| Debt-to-equity | Total debt ÷ shareholders' equity | Financial leverage. What counts as "high" varies by industry; utilities carry more than software firms. |
| Return on equity (ROE) | Net income ÷ shareholders' equity | How efficiently the company turns shareholder capital into profit. Consistently high ROE often signals a durable advantage. |
| Dividend yield | Annual dividend per share ÷ share price | Cash income as a percentage of price. A very high yield can signal that the market expects a cut. |
| Payout ratio | Dividends ÷ net income | How much profit goes to dividends. Above 100% is unsustainable for long. |
No ratio means anything alone. A P/E of 30 is cheap for a company growing earnings 40% a year and expensive for one growing 3%. Compare each ratio with the company's own history and with direct competitors, and ask why a difference exists before deciding it is an opportunity.
Growth versus value
Two broad schools of fundamental investing differ mainly in what they are willing to pay for. Value investors look for companies trading below their estimate of intrinsic value, often with low P/E or P/B ratios, accepting slower growth in exchange for a margin of safety. Growth investors pay higher multiples for companies whose revenue and earnings are expanding quickly, betting that growth will justify the price. Both approaches have had long stretches of outperforming and underperforming. The common mistake in both is confusing a low ratio with cheapness, or a high ratio with quality, without reading why.
Qualitative factors
Numbers describe the past. The qualitative questions are about whether the future will look similar:
- Competitive advantage (often called a "moat"): what stops competitors from taking this company's customers? Brand, network effects, switching costs, patents, scale, or regulation are the usual answers. If you cannot name one, assume there is none.
- Industry dynamics: is the market growing, shrinking, or being disrupted? A great company in a dying industry has a ceiling.
- Management: do executives have a record of sensible capital allocation and honest communication? Read a few years of shareholder letters and compare what was promised with what happened.
- Risks: customer concentration, regulatory exposure, currency, litigation. The "risk factors" section of the annual report is written by lawyers, but it is worth skimming.
How traders use fundamentals
Even short-term traders benefit from a basic grasp of fundamentals, because the biggest single-day moves in most stocks come from fundamental news, above all the quarterly earnings report. Three points to understand:
- Expectations are what matter. Analysts publish forecasts for revenue and EPS. A company that beats the forecast often rises; one that misses often falls. A company that beats but lowers its guidance for next quarter frequently falls anyway. The stock reacts to the surprise, not the number.
- Earnings dates are known in advance. Holding a position through an earnings release means accepting a gap that no stop-loss can protect against. Many swing traders close positions beforehand or size them for a 10% to 20% overnight move.
- Fundamentals set the backdrop. A stock in a strong uptrend on a chart with accelerating revenue growth behind it is a different proposition from one rallying on hope. Traders who check the fundamentals quickly before a technical entry avoid some of the worst surprises.
The limits of fundamental analysis
A sound valuation can be right about the business and wrong about the trade for a very long time. Markets can stay irrational, cheap stocks can get cheaper, and expensive stocks can get more expensive. Forecasts are often wrong; even management is frequently wrong about its own next quarter. Financial statements can be aggressive without being fraudulent, and occasionally they are fraudulent. Treat every valuation as an estimate with a wide range of error, which is one more reason to size positions as if you might be wrong, as explained in our risk management guide.
Frequently asked questions
What is a good P/E ratio?
There is no universal number. The long-run average for the US market has been in the mid-to-high teens, but fast-growing companies routinely trade above 30 and slow-growing or cyclical ones below 10. Compare a company's P/E with its own history, its growth rate, and its closest competitors rather than against a fixed threshold.
What is EPS?
Earnings per share is a company's net income divided by its number of shares outstanding. It expresses profit on a per-share basis so that companies of different sizes can be compared, and it is the denominator of the P/E ratio. Diluted EPS, which accounts for options and convertible securities, is the more conservative figure.
Why does a stock fall after good earnings?
Because the results were already priced in, or because something else in the report disappointed: weaker guidance for the next quarter, slowing growth in a key segment, or shrinking margins. Stock prices move on the difference between results and expectations, not on whether the results were good in absolute terms.
Is fundamental or technical analysis better?
They answer different questions. Fundamental analysis estimates what a company is worth; technical analysis describes what its price is doing and where risk can be defined. Long-term investors lean on fundamentals, short-term traders lean on technicals, and many people use fundamentals to choose what to trade and technicals to choose when.
Where can I read a company's financial statements for free?
In the US, every public company's filings are available on the SEC's EDGAR database, and most companies republish them on the investor relations section of their website. Broker platforms and free finance portals summarize the key figures and ratios.
