Lesson 2 of 6
The hour that kills most ideas
The cheapest checks first, in an order that ends most research inside an hour, and why ending is the good outcome rather than a failure of nerve.

In one minute
- Run the checks in order of cost, cheapest first, and stop at the first one that refuses the sentence you wrote.
- Four checks, none taking more than fifteen minutes, and most ideas do not survive them.
- Stopping is the good outcome: the hour was the point, and the alternative is a week.
Most research should end quickly. That is not cynicism, it is arithmetic: there are thousands of covered companies and one of you, so the binding constraint is how fast you can stop.
Four checks, in order of cost
The hour
-
Is there enough filed history. One lookup. If the record cannot support the reading your sentence needs, stop or narrow the sentence.
-
Do the figures your sentence names exist. Ten minutes. At some filers the standard ratios are refused for stated reasons, and if your sentence rests on one of them you need a different sentence.
-
Does the direction of the evidence match the sentence. Twenty minutes. Print the figure your sentence names across the filed years and look at it before reading anything anybody wrote about it.
-
Is there an obligation that decides. Fifteen minutes. Read the maturity schedule and the commitments note. If a dated obligation dominates, your sentence about operations is not the load-bearing one.
Why this order
Because each check is cheaper than the one after it and each can end the hour on its own. A reader who reads the annual report first has spent the hour before reaching check one.
The order is also roughly the order in which the answers are unambiguous. Check one is a lookup. Check four is a judgement. Spending judgement before spending lookups is the general error.
Check two is the one people skip
The bridge courses met a filer where interest coverage, the current ratio, the quick ratio and a debt-to-equity figure were all refused, each for a stated reason. A reader whose sentence was about liquidity at that company needed to know that in the first ten minutes, not in the fourth hour.
The general form: before relying on a figure, confirm the company produces it. Where it does not, the absence is itself informative and is usually pointing at the figure that does answer the question.
What stopping looks like
Writing one line: the idea, the check that ended it, and the date. Three seconds, and it stops the same idea being researched again in eight months.
What it does not look like is a conclusion about the company. An idea that failed check two failed because your sentence did not fit that filer's statements, which is a fact about the sentence.
When not to stop
One case. If a check refuses the sentence but the reason it refuses is interesting, the correct response is to rewrite the sentence rather than to abandon the company.
The filer whose credit ratios were all absent is the example: the sentence about liquidity failed, and the replacement sentence, about a dated obligation against cash generation, was better than the original and took five minutes to write.
Check yourself
Why are the checks run in order of cost?
- Because the cheap ones are more reliable
- Because each can end the hour on its own, so spending the expensive ones first wastes the hour
- Because the data arrives in that order
Show the answer
Answer: B.
The order is also roughly the order in which the answers are unambiguous: check one is a lookup and check four is a judgement.What does check two establish?
- Whether the company is financially sound
- Whether the company produces the figures your sentence rests on, since some filers refuse several for stated reasons
- Whether the filed history is long enough
Show the answer
Answer: B.
Where a figure is absent the absence is informative, and it usually points at the figure that does answer the question.A check refuses the sentence for an interesting reason. What is the correct response?
- Abandon the company
- Rewrite the sentence, because the replacement is often better than the original
- Override the check and continue
Show the answer
Answer: B.
The example in the bridge courses replaced a failed liquidity sentence with one about a dated obligation against cash generation, in five minutes.Sources

What this leaves out
- The four checks are the four this academy found cheapest and most decisive. They are not a complete list and a reader with industry knowledge will add their own.
- The distribution breakpoints describe a single date and one cohort of companies with filed statements on record. They are not a time series and not the whole US market.
- Stopping an idea after an hour is a decision about where to spend time, not a conclusion about any company.
