The share price on a screen tells you what people are paying for one slice of a company right now. It does not, by itself, tell you whether that price is cheap, fair, or expensive — for that you need to think about what the underlying business is actually worth. That question — valuation — is what this path is about.
It builds up one idea at a time, in plain English: what makes a company worth anything at all, how earnings and the price-to-earnings (P/E) ratio let you compare companies of wildly different sizes, why revenue growth can justify a higher price, how profit margins and a durable competitive “moat” separate a good business from a fragile one, and finally the big idea behind serious valuation — that a company is worth the cash it will generate in the future, discounted back to today (the intuition behind a discounted cash-flow, or DCF, model). It closes by showing, qualitatively, how these same textbook ideas show up as inputs inside Quantustik’s own model.
It is general investor education, never personalized investment advice, and never a claim that any particular stock is cheap or a promise of any return. Every number used is a clearly labelled illustrative example, not a real measured figure.
Lessons
What makes a company worth something — A share is a slice of a real business, and market cap (price × share count) is what the market pays for the whole thing — which is why the share price alone can never tell you if a stock is cheap. Price is what you pay; value is what the business is worth.
Earnings and the P/E ratio — The most common valuation yardstick: earnings are profit, EPS splits it per share, and the P/E ratio (price ÷ EPS) is roughly how many years of earnings you pay for — letting you compare companies of very different sizes.
Revenue and growth — Revenue is the “top line” (sales before costs); earnings are the “bottom line.” Because a business is a claim on future profits, how fast it grows changes what it is worth — and price-to-sales values companies that aren’t profitable yet.
Margins and moats (competitive advantage) — Margins show how much of each sales dollar a company keeps as profit; return on equity measures profit against invested capital; and an economic moat (Buffett’s term) is the durable advantage that lets a business keep high margins instead of having competitors compete them away.
Intrinsic value vs. market price (a beginner’s DCF) — The big idea behind serious valuation: a company is worth the future cash it will generate, discounted back to today (a DCF, from John Burr Williams). The gap between that intrinsic value and the market price is Benjamin Graham’s margin of safety.
How valuation feeds our model’s value & quality signals — The same valuation ideas become model signals: a value signal rewarding a lower P/E, a quality signal rewarding high ROE and healthy margins, and a growth signal — inputs among many, reported with calibrated confidence rather than false certainty.
Investor education only — not investment advice, and never a promise of profit. Every investment can lose value.
