Before buying, the homework gets done properly: read the filings, check the industry, run the valuation. After buying? The typical move is closing the app and waiting for time to deliver the verdict. Buying gets treated as the finish line, and everything after is idle waiting. But buying is not the finish line; it is the start of the homework. On every day of ownership, the original reasons for buying are tested against reality. The work is not finished. It has just opened.
Three rulers, measuring the original reasons
One system puts the procedure bluntly: buying does not mean holding motionless. It means building dynamic tracking rulers, in three classes. The first is the asset anchor. Some companies keep their value on the back of the balance sheet: hidden assets sit outside the headline numbers but surface in announcements on land reservation, demolition, and asset disposal. CIMC is the example often cited for this class. Whether the asset exists, whether it has moved, what it is worth — the announcements say so. The second is the earnings anchor. Look at the vesting conditions attached to equity incentives: each year, does the return on equity excluding non-recurring items meet the bar, does revenue growth meet the bar? The underlying logic is hard: an equity incentive plan is the lowest performance promise management signs in its own name. Check once a year: met, the promise-keeper can deliver; missed, the fundamental logic has broken — heavier than any research report. The third is the industry inflection. Has policy changed, where is capital spending heading, has the competitive landscape moved? Centralized procurement rewrote the drugmakers, 5G spending the equipment chain, defense budgets another list of names. Policy, capital expenditure, competitive structure — any one of them can rewrite the foundation of an industry. The three rulers never measure the share price. They measure one thing: whether the original reason for buying still stands.
Close the app, and the industry stays open
Some will say real value investing means buying and then closing the app for a decade, and that daily tracking is the anxiety of speculators. It deserves a serious answer. The problem is what gets tracked: the rulers do not measure price. The asset anchor, the earnings anchor, the inflection — all three measure whether the reasons for buying still hold. The app can be closed; the industry does not close with it. By the time the app is reopened, the reasons may be long gone while the position remains. Ordinary investors lose the most exactly here: news reaches the holder last in line.
The ruler measures a promise, not a quarterly mood
There is a second objection: if performance is watched so closely that a single missed year triggers an exit, would every good company be washed out? The question assumes a jumpy ruler. The ruler is blunt. It does not measure quarterly moods; it measures return on equity excluding non-recurring items and revenue growth against the vesting conditions of equity incentives. Those conditions are the lowest promise management signed itself. When the very people who made the promise cannot keep it, that is a broken logic, not volatility. Only someone who mistakes a promise for a mood washes out a portfolio of good companies in a year.
When the logic goes, what remains is only a position
The hardest objection comes last: if long-termism is the faith, then even when the logic changes the stock should be held — holding is what deserves compounding. This sounds the most like faith, and has the largest flaw. The principal of long-termism is “unchanged.” Take the unchanged away, and long term is down to an empty word. The system is blunt about it: once the long-term core logic is broken, cut and exit unconditionally. There is no long-termism that holds to the bitter end. Compounding presupposes that every stretch of holding has a reason. When the reason is gone, what remains in the account is a position, and a position does not make judgments on anyone’s behalf. Holding without compounding is not faith; it is the refusal to recheck.
Ownership is never lying flat. After buying, the homework starts: three rulers standing there, checked on a schedule. Logic intact, hold; logic gone, walk. No sentiment in between, and no face either. The rulers do not guarantee gains; they guarantee a clean exit — every sale has a source, every holding has a basis. What can be held is the logic, not the ticket.
