How to find wonderful companies at fair prices

Start with the universe of companies that pass strict quality thresholds: consistently high returns on invested capital and equity, healthy growth, and manageable debt. Most companies never clear this bar — that's the point. A high price can be debated; a weak business can't.

From that filtered list, choose businesses that mean something to you — products you use, industries you work in, models you can explain in a sentence. Peter Lynch built a career on this: invest in what you know. Familiarity isn't sentimentality: when you understand how a company makes money, you can tell a temporary stumble from a broken story. If you can't explain it, skip it, no matter how good the numbers look.

For each candidate, look at a decade of evidence, not a single hot year. A few numbers carry most of the signal:

• Return on invested capital (ROIC) — the cleanest measure of business quality: how much profit the company generates per dollar it puts to work. Sustained high ROIC usually means a durable competitive advantage — a moat.
• Return on equity and assets (ROE, ROA) — complementary return lenses; together with ROIC they show whether management compounds shareholder capital effectively.
• Growth rates — earnings, revenue, equity, and cash-flow growth over ten years. Consistency matters more than any single number.
• Debt— a wonderful business doesn't need leverage to look wonderful. Low debt relative to equity and earnings means bad years are survivable.

Wonderfolio condenses this into quality, moat, and management scores with ten-year sparklines for each underlying metric — so a decade of financial statements reads at a glance. A peers view puts the same numbers next to competitors, because "good" is always relative to the industry.

Price is what you pay; value is what you get. A company's intrinsic valueis an estimate of what the business itself is worth — independent of today's stock quote. Nothing about it is guesswork or gut feel: every input comes from the company's own published financial statements.

Here's the shape of a typical earnings-based estimate. Take current earnings per share. Grow them forward about a decade using a conservative growth rate drawn from the company's own history. Apply a reasonable price-to-earnings multiple to get a plausible future price. Then discount that future price back to today's dollars at the minimum annual return you'd accept for tying up your money. The result: what the business is worth today to someone demanding that return. Asset-based methods instead start from book value — what shareholders own outright; cash-flow methods discount the actual cash the business throws off. Different doors into the same house.

The methods differ on purpose: when independently calculated estimates land close together, you can trust the range; when they disagree wildly, that itself is information — dig into why before trusting any of them.

Two companion numbers make valuation concrete. The margin-of-safety price— the concept Benjamin Graham called the three most important words in investing — is the intrinsic value estimate with a steep discount applied — think of it as the "everything must go" price. Buying at half of what a business is conservatively worth means even a flawed estimate leaves room to be wrong. The payback price and payback time ask a businesslike question: if you bought the whole company, how many years of its earnings would repay your purchase? Fewer is better.

Growth assumptions drive these estimates, so Wonderfolio shows both a composite growth rate derived from the company's own history and the analyst consensus — the latter purely as context. Nothing in the valuations depends on analyst predictions.

Spreadsheet-proof companies still fail for human reasons. Before committing real money, research the parts no screener can score: who runs the company and how long they've been there, how candidly they communicate with shareholders when things go wrong, where the moat could erode, what the next decade plausibly looks like. Annual letters, earnings calls, and a little industry reading go a long way.

This step happens outside any app — deliberately. The numbers tell you where to look; they don't tell you what you'll find.

Most wonderful companies trade above their margin-of-safety price most of the time. That's fine — the workflow's edge is patience. Every company gets three zones built from its valuation: buy (price at or below the margin-of-safety level), watch (approaching it), and sell (rich relative to value). Add your researched candidates to the watchlist and Wonderfolio notifies you when a price crosses into a new zone — no daily chart-staring required.

When a company you've already researched enters the watch zone, get ready in your brokerage app: set a price alert at your target, or place a limit order at the price you decided on calmly, in advance. The goal is that by the time the market offers your price, the decision was already made — all that's left is execution.

If you've studied value investing, none of these formulas are secrets — they're in books decades old. What the app replaces is the grind: pulling ten years of statements, normalizing them, maintaining the spreadsheets, recomputing on every earnings report. Wonderfolio does that part continuously, for every company at once. The judgment — what you understand, what it's worth to you, when to act — stays yours.
