If you're eyeing a company to invest in, you need to know how to evaluate its investment worthiness. There are plenty of evaluation strategies and methods, but a key approach is fundamental analysis. This guide explains what fundamental analysis is, how it differs from technical analysis, and how to use it to assess whether a stock may be undervalued or overvalued.
What is fundamental analysis?
Fundamental analysis is a method of evaluating a stock by examining the underlying business (not just price movements). It uses financial statements and other information—such as management quality, competitive position, industry trends, and economic conditions—to estimate intrinsic value.
Once you have an intrinsic value estimate, compare it with the current stock price. If the stock trades below that value, it may be undervalued; if it trades above it, it may be overvalued.
To perform a fundamental analysis of a company, investors typically look at:
Company data: revenue, profit, assets, and the performance and reputation of the company's executive leadership.
Industry data: how the company compares with competitors and which trends are shaping its sector.
Macroeconomic data: how factors such as inflation, interest rates, and consumer demand affect the business environment.
Principles and types of fundamental analysis
Fundamental analysis generally breaks down into two main categories:
Quantitative analysis: deals with measurable financial data like revenue, profit margins, debt levels, and cash flow. It's all about numbers you can plug into a spreadsheet.
Qualitative analysis: examines factors that can't be easily quantified, like management quality, brand recognition, patents, competitive advantages, and industry positioning.
A solid fundamental analysis uses both. The numbers tell you how the company is performing right now, while the qualitative factors reveal whether that performance is sustainable.
Fundamental analysis vs. technical analysis
If fundamental analysis is about looking at the business, technical analysis is about looking at the stock's price action.
Fundamental analysis | Technical analysis |
|---|---|
| Examines company financials, management, and industry position | Studies price charts, volume, and market patterns |
| Used to determine intrinsic value | Used to predict short-term price movements |
| Typically for long-term investors | Typically for active traders |
| Answers "what to buy" | Answers "when to buy" |
Some investors use a mix of both — fundamental analysis to decide what to buy, and technical analysis to time their entry.
How fundamental analysis works
Fundamental analysis requires three main steps: data gathering, interpretation, and valuation. You collect company, industry, and macroeconomic data, then interpret what it reveals about performance and financial health. Finally, you make your assessment.
Look at the financial statements
A company's financial statements are the core of fundamental analysis. They show where the company's money comes from and how it's spent.
Common sources of financial statements include a company's annual and quarterly reports, which are available through the System for Electronic Document Analysis and Retrieval Plus (SEDAR+) in Canada or Form 10-K and Form 10-Q filings in the United States. Financial statements can include:
Income statements, which show how much revenue the company brings in and how profitable it is over time. Look for trends in sales growth, operating income, and net profit margins.
Balance sheets, which show what the company owns (its assets) and what it owes (its liabilities), as well as the shareholders' equity. A balance sheet gives you a sense of how a company finances its operations and growth, and of its financial stability.
Cash flow statements, which track how cash moves through the business, including operating cash flow (the cash generated by operations) and free cash flow (the cash left after necessary investments). These figures help you gauge the company's ability to sustain and grow its operations. They're usually split into three sections: operating, investing, and financing.
Evaluate key ratios
Once you've reviewed the financial statements, you can use financial ratios to compare the company's current financial health and performance to its history, as well as against its competitors.
Here are some common ratios, and what they can tell you about a company's financial health.
Ratio | What it indicates |
|---|---|
| Price-to-earnings (P/E). Forward P/E (uses estimates of company’s earnings for next 12 months); Trailing P/E (uses company’s earnings from past 12 months) | Compares a company's stock price with its earnings per share (EPS), using either forward P/E or trailing P/E. Indicates how much investors are willing to pay for each dollar of profit. Reflects market expectations for future growth (though it can also reflect overly optimistic pricing) |
| Price-to-book (P/B) | Compares a company’s stock market price per share to its book value per share (net assets on the balance sheet); Helps show whether the market values the company above or below what its assets are worth on paper |
| Return on equity (ROE) / Return on invested capital (ROIC) | Measures how efficiently a company uses shareholders’ equity (ROE) or total invested capital (ROIC) to generate profits; Higher returns usually indicate effective leadership and strong profitability |
| Gross margin / operating margin | Shows how much profit the company keeps from each dollar of sales after covering its costs (gross margin after production costs, operating margin after operating expenses); Indicates how efficiently the company manages its costs and operations |
| Debt-to-equity and interest coverage | Indicate how much the company relies on debt financing (debt-to-equity) and how comfortably it can cover its debt payments (interest coverage); Useful for judging a company’s financial stability |
| Free cash flow (FCF) and FCF yield | Show how much cash the company generates after funding necessary capital investments, and how that cash generation compares to its market value (FCF yield); Indicate how financially flexible a company is |
| Dividend payout / coverage ratios | Measure the sustainability of dividend payments (the payout ratio shows what share of earnings is distributed as dividends; the coverage ratio shows how many times company earnings can cover those dividends); Help show whether the company is generating enough to pay (or increase) its dividends over time |
Consider qualitative factors
The numbers in financial statements and key ratios are the quantitative factors in a fundamental analysis. Qualitative factors can help explain why the numbers are what they are.
Examples:
Business model: how the company makes money.
Competitive advantages: the company's unique value propositions compared with competitors.
Management and decision-making: leadership experience, credibility, and the company's decision-making track record.
Look at the bigger picture
Every company is susceptible to external influences, like macroeconomic trends, industry dynamics, and regulatory changes.
These factors can include:
Interest rates, which affect borrowing costs and valuation levels.
Inflation, which impacts input costs (such as supplies and raw materials) and consumer purchasing power.
Economic cycles, such as recessions or periods of expansion, which influence consumer demand for products and services.
Sector trends, which can help you evaluate whether the company is operating within an environment that's growing, struggling, or facing emerging challenges.
Valuation methods to estimate intrinsic value
Once you've gathered and interpreted both the quantitative and qualitative data, the next step is to estimate what the company is actually worth. Common valuation methods include:
Discounted cash flow (DCF): estimates what the company's future cash flows are worth in today's dollars. Results can vary significantly based on your growth assumptions and discount rate.
Comparable multiples (comps): values a company by comparing it to similar companies using ratios like P/E and P/B. This offers a reality check for how the market values companies in the same sector.
Dividend discount models (DDM): values a company's stock based on expected future dividends. This works well for mature, stable companies with consistent payout histories.
Because every model has its limitations, investors often use several valuation methods and then compare the results to see if they point to a similar value (called "triangulating"). This helps build a more well-rounded idea of what a company is truly worth.
Step-by-step guide to fundamental analysis
Look at the company's business overview to understand what it does exactly and how it makes money.
Review income statements, balance sheets, and cash flow statements. Look for multiyear trends in growth, profitability, and financial health.
Calculate key ratios (such as margins, ROE, P/E, P/B, and debt-to-equity) and compare them to averages of other companies from the same sector.
Assess the company's qualitative factors.
Do a preliminary valuation check. Estimate the company's value using the comps or by comparing to a ratio like P/E or P/B.
Identify business risks (what could hurt the company's performance) and test your assumptions (what could change your valuation view).
Continue your research to make a final assessment. You can focus on gaps or uncertainties to help you make a decision about whether or not the company is a solid option for long-term investment, rather than jumping to a buy/sell conclusion.
Pros and cons of fundamental analysis
Like any investment approach, fundamental analysis has its strengths and weaknesses. Knowing when it's most useful and where it can fall short can help you use it more effectively.
Pros:
Helps assess the risk, quality, and long-term sustainability of a company
Can inform a comprehensive, long-term view of a company's value
Encourages investment decisions based on real business performance and cash flows
Cons:
Sensitive to assumptions; small changes to quantitative factors can shift results
Differences in how companies report data and account for financials can make them harder to compare
Relies on historical data, while markets often move based on expectations for the future
Can be time-consuming to put together
Only as reliable as the quality of the information used
Fundamental analysis helps you understand a company's intrinsic value by studying its financial performance, business model, and economic context. By comparing that estimate with the market price, you can make more informed decisions about a stock's potential. Remember: your results depend on the quality of your data and the soundness of your assumptions.
