A nephew stands in front of the family with a plan. He wants to open a bottled-water and refills business in the trading center, and he is asking the family to put money behind him. The debate that follows is warm, serious, and entirely about the nephew. He is hardworking; remember the shop he ran at university. He is honest; he repaid his aunt to the shilling. He wakes early, he keeps records, he does not drink. Every word is true, and by the end of the evening the family has agreed to invest, having examined the swimmer thoroughly and never once looked at the river. Nobody asked how many other water businesses the trading center already has, how hard it would be for a fifth one to open next month, or whether anyone in that business, however hardworking, can charge more than the man across the road.
That scene is ours, invented for this essay. It could not have come from the book behind it, because the Investments Workbook: Principles of Portfolio and Equity Analysis, written by Michael G. McMillan, Jerald E. Pinto, Wendy L. Pirie, and Gerhard Van de Venter for the CFA Institute Investment Series, contains no scenes at all. It is the official practice workbook for the first level of the CFA program, the credential professional equity analysts train under: learning outcomes, concept summaries, and long problem sets, with no stories and no companies followed for more than a sentence. But its chapters on industry and company analysis contain the exact discipline the family skipped, and the discipline can be stated in one line: professionals never read a company alone. They read the river first, then the swimmer, and only then the price. This essay walks through that reading order, in plain language, for a family deciding whether to buy shares, back a relative, or size up a competitor.
The workbook is direct about the order of operations: industry analysis is a vital complement to company analysis, because the analyst has to understand the context a company operates in before its opportunities and threats mean anything. The tool it teaches for reading that context is a famous framework it borrows and applies, Porter's five forces. In the book's summary, "the profitability of companies in an industry is determined by five forces: (1) The influence or threat of new entrants," which depends on things like economies of scale, brand loyalty, cost advantages, switching costs, and regulation; "(2) the influence or threat of substitute products; (3) the bargaining power of customers; (4) the bargaining power of suppliers; and (5) the intensity of rivalry among established companies."
Strip the consulting language and the five forces become five questions a family can ask about any business in twenty minutes. How easily can someone new open up next door? Can customers get the same need met a different way entirely? Can customers squeeze the price because leaving costs them nothing? Can suppliers squeeze their side because they have alternatives and the business does not? And how bloody is the daily fight among the businesses already there?
The first question matters most, and the workbook says why with unusual bluntness: "industries with low barriers to entry tend to have low pricing power." If new competitors can enter easily, anyone who raises prices gets undercut by a newcomer, so nobody can hold a price above survival level, no matter how well they run their shop. This is the sentence the family needed on the nephew's evening. Bottled water and refills in a trading center is close to the textbook case of low barriers: little capital, no licenses of consequence, no brand loyalty, suppliers who will sell pumps and jerricans to anyone. The nephew can be the finest operator in the district and still spend his working life unable to charge one shilling more than the man across the road, because the structure of the river, not the quality of the swimmer, sets the price. The family was not wrong that character matters; a dishonest nephew would sink in any river. They were wrong to think character was the whole analysis. A great manager in a bad structure is still fighting uphill, and the hill does not care how early he wakes.
The second reading the analyst makes is of the industry's age. The workbook teaches a five-stage industry life-cycle model, attributed to Hill and Jones, and the stages are worth keeping as a plain list:
Why should a family care about a chart from a strategy textbook? Because the same growth number means a different thing at each stage, and misreading the stage is one of the most common ways money is lost on "obviously growing" businesses. Twenty percent growth in a growth-stage industry is the tide lifting every boat, and the question is only whether your boat is seaworthy. Twenty percent growth in a mature industry is not a tide, because there is no tide; it is one boat taking water from another, which is a much harder story to sustain, or it is a temporary blip about to revert. Mobile money in East Africa in 2010 was a growth industry; a new agent could prosper on the tide alone. The same agency business in a saturated market fifteen years later is mature: a new agent prospers only by beating incumbents at their own corner. Same business, same hard work, entirely different odds, and the difference was the industry's age, visible in advance to anyone who thought to ask. The shakeout stage deserves special respect from families backing small ventures, because it is precisely when growth slows and capacity has overshot that the hardworking latecomers, the ones who entered because everyone seemed to be winning, are the first to be washed out.
Only after reading the river and its age does the analyst finally turn to the question the family started with: is this worth the money? And here the workbook teaches the mental move that separates professional buying from everyone else's, in one sentence: "An analyst estimating intrinsic value is implicitly questioning the market's estimate of value." A price, any price, a share price on the Nairobi exchange, the sum the nephew says his business needs, the figure a land seller names, is an opinion held by other people. The analyst's job is to build an independent estimate of what the thing is worth, and only then compare. In the book's clean formulation, if your estimated value exceeds the market price, you infer the asset is undervalued; if your estimate is less than the price, you infer it is overvalued. If you have no estimate of your own, you have no opinion at all; you are simply adopting the seller's.
How do professionals build the independent number? The workbook sorts every tool in the trade into three families, and the sorting is more useful to a lay reader than any single tool. Present-value models ask: what are all the future payouts this asset will hand me, counted back to what they are worth today? Multiplier models ask: what are buyers paying for each unit of earnings or sales in comparable businesses, and is this one priced above or below its peers? Asset-based models ask: if this venture stopped tomorrow, what would its assets fetch minus what it owes? A family can run rough, arithmetic-only versions of all three on the nephew's plan in an evening: what cash can this hand back per year against what goes in; what did the other water businesses in town effectively cost to build; what would the pumps, tanks, and stock resell for. No algebra is required for any of it.
The workbook adds a warning that amateurs skip and professionals live by: analysts use more than one model on the same asset, "because of concerns about the applicability of any particular model and the variability in estimates that result from changes in inputs." In plain terms: every method is wrong in its own way, so triangulate. If the three rough answers land in the same neighborhood, you have something. If they scatter wildly, the scatter itself is the finding: you do not yet understand the business, and the honest next step is more questions, not a transfer.
One more reading remains, the fine print, and it applies with special force when the deal is inside the family. The workbook's chapter on equity securities defines what a share actually is: "Common shares represent an ownership interest in a company and give investors a claim on its operating performance, the opportunity to participate in the corporate decision-making process, and a claim on the company's net assets in the case of liquidation." Three distinct promises: a slice of the results, a voice in decisions, and a place in the queue if it all ends. The book then spends pages showing how those promises vary by share class: preference shares that get paid before common shareholders but usually carry no vote; cumulative preference shares whose skipped dividends pile up as a debt to be cleared before common holders see anything, while noncumulative ones simply lose the skipped year.
The lesson for a family is that "shares" is not one thing, and the word without paperwork is not any thing. When the family "takes shares" in the nephew's business on a handshake, which of the three promises did it buy? A slice of profits, and who calculates them? A voice, and on what decisions? A claim on the pumps and stock if it fails, and against whose word? Unwritten equity tends to mature into whichever promise costs the operator least. This is not cynicism about nephews. It is the recognition that the workbook's authors spend pages on share classes because even in formal markets, with regulators watching, what you are owed depends entirely on what was written. Inside a family, where nothing is written, it depends on memory and goodwill under stress, which is the most expensive legal system in the world. Here the book, which knows nothing of families, stops. We go one step further: back the nephew if the river, the stage, and the numbers say yes, and then write the terms as if he were a stranger, precisely because he is not. Written terms are not distrust. They are the reason there is still a family council in ten years.
Turn the analyst's reading order into a family habit this month. Before the next shilling goes into any business, a listed share, a relative's venture, your own expansion, someone must write one page in this order: the river (the five questions, answered honestly, with the barriers-to-entry question first), the age (which of the five stages, and what the growth number therefore means), the value (three rough numbers by three rough methods, and whether they agree), and the promises (exactly what the money buys, in writing). Store that page, and every one that follows, in your family's Wisdom Library in LegacyPot, alongside the proverbs and the stories, because a repeatable way of judging a business is precisely the kind of wisdom families fail to transmit: the elders learn it through expensive mistakes and take it with them, and each generation pays the tuition again. A shelf of one-page analyses, some that led to yes, some to no, with what happened afterward noted in the margin, is a school your grandchildren can attend for free.
The nephew deserved better than an evening about his character. He deserved a family that read the river first. So does yours.
