Fundamental Analysis and Why It Differs From Price Data
Market data and business data are two fundamentally different kinds of information. Price data — open, high, low, close, and volume — is a continuous record of transactions. It tells you what buyers and sellers agreed to at a given moment, but nothing about the company's operations, its customers, its costs, or its obligations. Fundamental data comes from a different source entirely: financial statements, annual reports, quarterly filings, and earnings releases prepared under accounting standards and, in most jurisdictions, reviewed or audited by an independent firm. The questions that define fundamental analysis are straightforward. How much did the company earn? How much did it sell? What share of that revenue survived as profit? What was returned to shareholders, and in what form? How many shares exist, and what does each share represent in terms of book value and earnings? Is the business expanding or contracting? None of these answers can be read off a price chart. It is worth being precise about what fundamental analysis is not. It is not a guarantee of future prices, and it is not inherently superior to price-based study. The two approaches answer different questions. Price data describes market behavior and the balance between supply and demand for shares. Fundamental data describes the underlying business that those shares represent. Many participants use one, the other, or a combination, depending on their time horizon and method. The point of this section is simply that these are distinct information sets, and treating them as interchangeable leads to confusion.
Earnings: The Bottom Line and What It Actually Means
Earnings, also called net income or the bottom line, is what remains after all costs, operating expenses, interest, and taxes are subtracted from revenue. It sits at the end of the income statement and is usually the headline number in an earnings release. It is also the figure most often quoted in the financial press and the basis for the widely used price-to-earnings (P/E) ratio. Two cautions matter here. First, earnings are an accounting construct, not cash. Accrual accounting recognizes revenue when it is earned and expenses when they are incurred, not necessarily when cash changes hands. A company can report healthy earnings while cash flow is weak, for example if customers are slow to pay or if inventory is building up. For that reason, analysts frequently compare net income with cash flow from operations to see whether reported profits are being converted into actual money. Second, reported earnings include items that may not repeat. Asset sales, legal settlements, restructuring charges, and write-downs of goodwill or inventory can swing the bottom line in a single period. Companies often present an adjusted or non-GAAP figure that excludes such items, arguing it better reflects ongoing operations. Those adjustments can be informative, but they are also management's own framing, and the gap between reported and adjusted earnings varies widely between companies. A reader who only looks at the adjusted number may miss genuine costs. Earnings also tend to be cyclical. Businesses tied to commodities, construction, or consumer discretionary spending can post strong profits near a cycle peak and losses near a trough. Comparing a single year's earnings across such a cycle without context can be misleading.
