Every method you'll ever encounter descends from two questions. Fundamental analysis asks: what is this thing actually worth? Technical analysis asks: what is the crowd actually doing? Different questions, different evidence, different timescales — and a century of internet-forum wars pretending you must choose one religion.
The fundamental lens: the business
Fundamentals treat the stock as what Lesson 2 said it is — a slice of a company. So the analyst reads what the company reports: revenues, profits, debts, growth (the four statements are a free lesson in the markets course). The bet underneath: over time, price follows the business. A company that compounds its earnings for a decade will drag its stock up with it, whatever the chart did along the way. Strengths: it anchors you to something real, and it's the natural lens for horizons of months to decades. Weakness: "over time" can be agonizing — a stock can stay mispriced far longer than your patience or your account survives, and fundamentals say almost nothing about when a move starts.
The technical lens: the crowd
Technicals treat the chart (Lesson 3) as the evidence — the recorded behavior of everyone who actually put money where their opinion was. The bet underneath: crowd behavior leaves patterns, because humans repeat themselves. Trends persist; prices remember old battlegrounds; participation confirms or betrays a move. Strengths: it works on any timeframe, gives concrete entry and exit levels, and reacts in real time. Weakness: the chart knows nothing about value — it will draw the same lovely pattern on a great business and a fraud — and its patterns are tendencies, never promises.
Why the best traders use both
Look at how the greats actually operated. William O'Neil demanded strong earnings and a proper chart pattern before buying. Nicolas Darvas called himself a "techno-fundamentalist" — companies with a future, bought only when the chart confirmed. Stan Weinstein's chart method leans on how the stock acts around its fundamentals-driven peers. The pattern: fundamentals choose what deserves your money; technicals choose when it gets it. One lens finds the argument worth joining (Lesson 1's framing); the other times your entry into it. On this site, the Fundamentals and Technicals tracks teach the lenses separately so you learn each honestly — then the strategy playbooks show them welded together.
Check yourself: a friend says "charts are astrology — only earnings matter." What's the fair, one-sentence reply?
Earnings may decide where the price ends up, but they don't tell you when the move starts, how far the crowd will overshoot, or where to admit you're wrong — that timing information lives in the market's behavior, which is all technical analysis claims to read. (The reverse correction applies to chart purists: the chart can't tell a great business from a doomed one.)
