Equity Analysis & Valuation

CTRT Learn · Core · 13 min read

In brief

  • A stock is a fractional ownership of a real business — not a lottery ticket or a flashing number.
  • Fundamental analysis estimates what a company is worth; the market gives you a price. The gap is the opportunity.
  • Valuation multiples like the P/E ratio are quick shorthand for how expensive a stock is relative to what it earns.
  • Price and value are not the same thing. The whole craft is buying value for less than its price.

A share of stock is a slice of a company — its factories, brand, profits, and future. Equity analysis is the discipline of figuring out what that slice is actually worth, then comparing it to what the market is charging. This lesson builds directly on accounting and corporate finance, turning statements into a judgement about a stock.

Price is not value

The market quotes a price every second — what someone will pay right now. Value is what the business is fundamentally worth, based on the cash it can generate. The two are often different, because price is set by crowds of emotional people (see the Behavioral Finance course) while value moves slowly with the business. As the investor Benjamin Graham put it, the market is a voting machine in the short run and a weighing machine in the long run. Equity analysis is the weighing.

Top-down and bottom-up

Analysts approach a stock from two directions, usually both:

  • Top-down — start with the big picture: the economy, then the industry, then the company. Is this a growing sector with favourable conditions?
  • Bottom-up — start with the company itself: its financials, products, and competitive position, regardless of the macro backdrop.

Together they answer two questions: is this a good business, and is it well-placed in a good environment?

What makes a quality business

Before valuing a company, judge whether it's worth owning at all. Strong businesses tend to share traits:

  • A moat — a durable competitive advantage (brand, network, scale, switching costs) that protects profits from competitors.
  • Pricing power — the ability to raise prices without losing customers.
  • High returns on capital — it earns a lot relative to the money invested in it.
  • A strong balance sheet — not drowning in debt, able to survive bad years.
  • Capable, honest management — allocating capital wisely and treating shareholders fairly.

A wonderful business at a fair price usually beats a mediocre one at a cheap price.

Valuation multiples: the quick read

Multiples express price relative to some fundamental, letting you compare companies fast:

  • P/E (price-to-earnings) — price per share ÷ earnings per share. Roughly, how many years of current profit you're paying for. High P/E implies high growth expectations.
  • P/B (price-to-book) — price relative to the company's net assets.
  • P/S (price-to-sales) — useful for companies not yet profitable.
  • EV/EBITDA — enterprise value relative to core operating earnings; less distorted by debt and tax.

Multiples are shorthand, not truth. A "cheap" low-P/E stock may be cheap for a reason (a dying business); an "expensive" one may be worth it (rapid, durable growth). Always compare a company to its peers and its own history, and ask why the multiple is where it is.

Intrinsic value: the deeper estimate

The most rigorous approach, introduced in the Corporate Finance course, is the discounted cash flow (DCF): estimate the company's future free cash flows, discount them to today, and sum them to get an intrinsic value per share. Compare that to the market price. If your estimate is well above the price — with a sensible margin of safety to absorb being wrong — that's a potential buy. A DCF forces you to state your assumptions about growth, margins, and risk explicitly, which is its real value, more than the precise number it spits out.

Putting it together

Real analysis blends all of this: understand the business and its moat, check the financial health through the statements, estimate intrinsic value, and sanity-check with multiples against peers. Then compare to the price and decide whether the market is offering value or charging too much. The goal is never to predict the next move — it's to buy good businesses for less than they're worth and let time do the rest. Even great analysis is an estimate, so demand a margin of safety and accept you'll be wrong sometimes.

Key terms

  • Fundamental analysis — valuing a stock from the underlying business.
  • Intrinsic value — what a company is truly worth, vs its market price.
  • Moat — a durable competitive advantage protecting profits.
  • P/E ratio — price relative to earnings; a core valuation multiple.
  • Margin of safety — buying well below your value estimate to absorb error.
