Fundamental Analysis: Valuing the Business Behind the Ticker
Where technical analysis asks what participants are doing, fundamental analysis asks what the underlying business is actually worth. This section works through the metrics that carry information, and the particular way each of them can mislead a careful reader.
Fundamental analysis asks a different question from everything else on this site. The rest of the site asks "what are participants doing?"; this section asks "what is this business worth?"
The two are not rivals, whatever the partisans of each will tell you. They operate on different timeframes and answer different questions, and most experienced investors use both: fundamentals to decide what to own, technicals to decide when, and where the idea has been proved wrong.
What the statements tell you
- Income statement: revenue, costs and profit over a period. The most watched and the most adjustable.
- Balance sheet: what the company owns and owes at a point in time. Where debt problems become visible first.
- Cash flow statement: cash moving in and out. The hardest of the three to manipulate, and therefore the most informative.
Valuation is a comparison, not a number
No metric carries meaning on its own. A P/E of 30 is expensive for a utility and cheap for a company compounding earnings at 40% a year. Every fundamental figure only starts to mean something once you read it against three references: the company's own history, its direct competitors, and the growth rate that would be needed to justify it.
Where it fits with the rest of this site
If you hold positions for days or weeks, fundamentals matter to you mainly as catalysts: earnings dates to stay clear of, guidance that resets a stock's whole range. If you hold for years, they are most of what matters, and the price action in between is noise.
Whichever timeframe you work on, the risk rules do not change. A strong fundamental thesis is no substitute for a stop, and "the business is good" may be the most expensive reason anyone has ever given for holding a losing position.
Key Stock Metrics: What Each One Measures and Hides
Roughly a dozen figures account for most of what matters about a company, and knowing what each one omits proves more useful than knowing how it is calculated.

Value Traps: Why Cheap Stocks Keep Getting Cheaper
Every multiple is calculated against earnings already reported, so a company in structural decline screens cheap the whole way down. Falling margins alongside falling revenue is the clearest warning available.

Insider Buying vs Selling: Which Signal Matters
A sale can be explained by tax, diversification or a schedule arranged eighteen months earlier. A purchase has one explanation, and that asymmetry is where the usable signal sits.
Fundamental Analysis FAQs
What is fundamental analysis?
Evaluating a company by its financial statements, competitive position and economics, to estimate what the business is worth independently of what its shares currently trade at. Where technical analysis studies participant behaviour, fundamental analysis studies the underlying asset.
Which fundamental metrics matter most?
Free cash flow, return on invested capital, operating margin trend, and the debt-to-EBITDA ratio cover most of what matters. Earnings per share is the most quoted and the most manipulable, because it sits at the end of a long chain of accounting choices.
Is a low P/E ratio good?
Not by itself. A low P/E means the market expects earnings to fall, and it is frequently right. The question is always why the multiple is low: a temporary problem the market has overreacted to, or permanent deterioration that has not finished showing up in earnings yet.
Can you use fundamental and technical analysis together?
Yes, and it is common. A frequent combination is using fundamentals to decide what to own and technicals to decide when to buy it and where the thesis is invalidated. The failure mode is using fundamentals to justify ignoring a stop, which converts a trade into an indefinite hold.
Do fundamentals matter for short-term trading?
Barely, except around catalysts. Over days to weeks, price is driven by flow and positioning rather than valuation. Fundamentals matter enormously over years and almost not at all over hours, which is why the timeframe you trade determines how much attention they deserve.
