When an account loses big, what is the most common cause? Failing to find a great company — or stepping on a mine that could have been avoided? Go through the worst-hit accounts and the cause of death is rarely “missed the winner.” Mostly, they stepped on something. The first step in stock picking is not finding good companies. It is ruling out the ones that die for certain.
Mines First, Value Later
Almost every stock-picking guide teaches how to find good companies. But mines come first in the logic: if the mines are not cleared, even the right company cannot be held — the account hits zero, and every later opportunity belongs to someone else.
There is a framework that turns this order into a checklist. Its opening line is worth keeping: it is the reverse verification of all theory. A theory told the usual way teaches you how to win; this list teaches you how not to die. Every line on a minefield list was once the last line of somebody’s account.
Four Mines
Mine one: the watered-down stock. Assets packaged up for the IPO, inflated on the books, with no sustained cash flow behind them. One question verifies it: strip away the packaging — does this company collect operating cash flow, year after year? If not, stay away.
Mine two: the fake transformation. Brokers pivoting to wealth management, carmakers crossing over from other industries, diversification with no technical foundation — each story bigger than the last. Meituan’s blind diversification is the case study in value destruction: the expansion never built a moat; it burned shareholders’ money. One question: for this so-called transformation, where is the technical support?
The original list has another entry, about brands being bid up into valuations — that account was settled in an earlier piece, so it stays out of this one.
Mine three: applying consumer-style valuations to cyclical sectors. Lithium-battery EVs and pure automakers are strongly cyclical industries with a visible ceiling; consumer-stock valuation logic cannot stretch over them. One question: does this industry’s profit rise and fall with the cycle, or grow steadily with demand? The first kind cannot be priced like the second.
Mine four: hot sectors at high multiples. When everyone agrees, a dynamic P/E above 100 needs years of growth to digest. Do that arithmetic first. If the numbers close, it earns a look; if not, walk around.
Four mines, and every one of them says the same thing: stay away, do not touch. It sounds negative. It is discipline.
Mines Are Computable Before They Explode
At this point the strongest objection arrives: mine-clearing is hindsight. Before every mine exploded, it looked like an opportunity — Meituan’s diversification was once called the second growth curve, and cross-industry carmaking was held up as a transformation model. Reverse-engineer the criteria from the outcomes, and anyone can “spot mines.”
This objection deserves a direct answer. The checklist does not screen for outcomes. It screens for features verifiable in advance: is there sustained cash flow, does the transformation have technical support, is the industry strongly cyclical, how many years of growth does the valuation need. All four are accounts computable before anything explodes — no rearview mirror required. Mines look like opportunities beforehand only when nobody runs the numbers; run them, and opportunity and mine separate. Meituan’s diversification looked like an opportunity, yes. But where was the technical support? That question was answerable at the time. The answer was never in the aftermath. It was in the question.
Survivors and Portfolios
A second objection follows: everyone-agrees rallies are where the money is — by the time anything is cheap, nobody mentions it anymore — and stocks bought at 100 times have produced huge winners.
A single case can afford a survivor; a portfolio cannot. When everyone is bullish at once, digesting the valuation depends on growth being delivered — and when it is not, what collapses is the principal. Yes, 100-times stocks have produced great winners, but that approach bets on a single case. Ten 100-times names in a portfolio is a bet no one can afford. Mine-clearing is not about catching every opportunity. It is about not being wiped out by the same four deaths.
Survive First
Clearing mines does not guarantee you own good companies. It guarantees the four modes of death do not zero you out. Survive first — only then does stock-picking even come up.
One boundary: this article recommends no stocks and makes no judgment on any current name; the cases are references within the framework, not investment advice.
