The Four-Number Stock Checklist — Which Parts Survive
Key takeaway
- Of the four numbers, one is a good beginner filter, one is backwards as a buy test, and two need a condition the video does not give.
- “The five-year chart goes up” describes the past. Every stock at the top of a bubble passes it — which is exactly when it is most expensive to pass.
- Scoring three out of four hides which one you failed, and the four are nowhere near equally important.

The checklist, sorted
The video's structure is good: open a free finance page, read four numbers, decide. The problem is one of the four, and the way the score is added up.
Worth saying clearly: giving a beginner a fixed, repeatable routine is more valuable than most stock advice on the internet, and “the best way to start is by taking action” is right. The fix here is to change one item and stop adding the score, not to throw the routine away.
The criterion to drop
“Has the stock generally gone up over five years?” is a fact about the past being used as a reason to pay today's price.
The video's reasoning is “a good stock usually shows consistent growth over time”, and it also asks whether the stock recovered from its dips, calling that resilience. Both of those are true of good businesses looking backwards. Neither survives being turned into a buy rule, because a rising price is precisely what makes a business expensive.
What the chart tells you
- What other people already paid
- Which story was popular
- Nothing about what you get
What decides your return
- What the business earns from here
- What you pay for those earnings
- How long that gap persists
There is a way to keep something from the chart: use it for orientation, not for the decision. How volatile has this been? Has it had a −50% year? Could I hold that? Those are real questions. “It went up, therefore buy” is earnings first, then price run in reverse.
The P/E band needs a sector attached
“Below 15 is cheap, 15–25 is average, above 25 means high expectations” is a reasonable summary of a US index average and a poor rule for any individual company.
The band also fails in the other direction. A utility on 14 and a software business on 32 are not cheap and expensive; they are different growth rates, different capital needs and different risk. A P/E only becomes a judgement once you say what earnings you expect next — see how to tell if a stock is cheap.
The dividend line, stated carefully
The video calls a dividend a reason to prefer a stock. It is a cash-flow preference, not extra return.
The description in the video — “dividends is literally you getting paid by the company just because you're holding their shares” — is what makes the yield feel like a bonus. Screening for it is not harmless either: it narrows you toward older, slower, more concentrated sectors, and about half the market pays nothing at all. Why dividends are not free money has the full argument.
Why “three out of four” is the real problem
Adding four unequal tests into one score means two very different stocks come out identical.
And the criterion that does the most work is the one the video treats as basic housekeeping. A size floor is a crude test, but it removes most of the ways a beginner's individual stock pick goes to zero.
The checklist worth keeping
Same routine, same ten minutes, one item swapped and no score.
- Size. Large and liquid, as the video says. This one is keep-as-is.
- Do I understand how it makes money? In one sentence, without jargon. This replaces the five-year chart — see invest in what you know.
- Is the price sane against its own history and its competitors? Not against a universal band.
- Could I hold it through a −50% year? Look at the chart for this, which is what a chart is genuinely good for.
- No score. If any of the four is a no, it is a no. Four notes beat one number.
Try this week
- Take a stock you own and write one sentence on how it makes money, without using any jargon.
- Compare its P/E with its own five-year range and with two direct competitors, not with a fixed band.
- Find its worst twelve-month drawdown and ask whether you would have held it.
- Replace any 3-out-of-4 style score in your notes with four separate written answers.
Common questions
Is a rising five-year chart a good reason to buy a stock?
No. It tells you what other investors already paid and nothing about what the business will earn from here. Every stock at the peak of a bubble has a rising five-year chart, which is exactly when the test passes most convincingly and costs the most. Use the chart to judge volatility you could live with, not to make the buy decision.
Is a P/E under 15 cheap?
Only relative to something. A universal band ignores growth rate, capital intensity and where a business sits in its cycle — cyclical companies look cheapest on a P/E precisely when their earnings are peaking. Compare a company with its own history and its direct competitors, and ask what the market expects to happen to those earnings next.
Should beginners only buy stocks above $10 billion in market cap?
It is a crude filter and a genuinely useful one. Larger companies are more liquid, better covered and far less likely to go to zero, so a size floor removes most of the ways a first stock pick ends badly. The cost is that it also removes the very large winners, which is usually a reasonable trade early on.
Do dividends make a stock a better investment?
Not by themselves. A dividend transfers cash from the company to you and reduces the share price by the same amount, so it changes where your money sits rather than how much of it there is. Screening for yield also tilts a portfolio toward a narrower set of older sectors, since roughly half the market pays no dividend at all.
What should a beginner actually check before buying a stock?
Four separate answers rather than a score: is it large and liquid, can you explain in one sentence how it makes money, is the price sane against its own history and its competitors, and could you hold it through a year down 50%. If any of the four is a no, it is a no — a three-out-of-four total hides which one you failed.
