What a Score Log Teaches After Forty Entries

A sector-relative score is only as useful as your evidence that it helps you. The cheapest evidence is a log: the score, its five pillar values, the calculation date, the peer group size, what you did, and what happened relative to the sector afterwards. Forty entries is about the point where the log starts to say something.

Sort by total first

If the high-score entries did not outperform the low-score entries relative to their sectors, either the weights do not fit your holding period or the holding period does not fit the weights. That is a finding about you and the tool together, and it is worth more than any single reading.

Then sort by pillar

Most people find that one pillar carried the result and one contributed nothing for their particular style. A long-term holder often finds quality and safety did the work; a shorter-horizon trader often finds momentum did. That is the only honest reason to reweight, and it should be done by writing the new weights down before the next batch of entries, so the next forty are a real test rather than a fit.

Judge outcomes against the sector

A stock that fell five percent while its sector fell fifteen was a relative win, and a score that pointed to it did its job. Judging against the index would score that entry as a loss and teach the wrong lesson. Sector-relative scores need sector-relative outcomes.

Keep the shape, not only the sum

Two entries with a total of 70 can have opposite pillar profiles. If only the total is logged, the log cannot later show that lopsided profiles behaved differently from balanced ones, which is often the most useful thing it has to say.

Turnarounds and Trailing Scores: Why a Rising Rank Lags a Recovering Business

A company that has fixed itself does not look fixed in a trailing score for a while. The filings that carry the improvement arrive one quarter at a time, and a sector-relative rank built from three-year growth and trailing margins moves slowly by design. This is a feature for most companies and a blind spot for turnarounds. Knowing where the blind spot sits is the whole trick.

What the score sees during a turnaround

Trailing margins still include the bad quarters, so business quality ranks low. Three-year revenue growth still includes the decline, so growth durability ranks low. Leverage taken on during the trouble keeps financial safety low. Valuation may look cheap on depressed earnings. Momentum, if the market has noticed the recovery, is the one pillar that can already be high. The total sits in the 30s while the business is visibly improving.

How to read it

Look at the direction of each fundamental pillar over the last three or four calculation dates rather than at its level. A quality rank moving from 10 to 20 to 32 is a recovery in progress, even though 32 is still a low number. The level says where the company has been; the trend says where it is going.

The pairing that matters

Rising momentum with rising quality is the market and the fundamentals agreeing on a recovery. Rising momentum with flat quality is a rally waiting for evidence. Rising quality with flat momentum is a recovery the market has not noticed, which is either an opportunity or a sign the market knows something the filings do not yet show. Each pairing is a different situation and the total cannot tell them apart.

Why the score is built this way anyway

A score that reacted quickly to one good quarter would also react quickly to one lucky quarter. Slowness is the price of not being fooled by noise, and for the large majority of companies that trade is right. For turnarounds, the reader supplies the speed by reading the trend.

Why the Same Stock Can Rank Differently on Two Research Sites

Open two research sites, look up the same company, and you will often find two different scores. Neither site is lying. The disagreement comes from four design choices made before any number is computed, and knowing them turns a confusing contradiction into useful information.

1. What the company is compared with

One site ranks against the whole market, another against the sector, a third against a hand-picked list of competitors. A software company with a P/E of 30 is expensive against the market and cheap against software. The comparison set is the biggest single source of disagreement.

2. Which metrics feed each question

Two sites can both call a pillar quality and build it from different inputs: one from return on capital, another from margins and margin trend. Both are defensible. They will not agree on every company, and they will disagree most on companies where the inputs point in different directions.

3. When the data was pulled

A score computed the day after a filing and one computed a week before it describe different quarters. If two sites show different numbers, compare their calculation dates before comparing anything else. The stale one is not wrong; it is late.

4. How the pillars are combined

An average forgives one weak pillar. A product punishes it. A weighted scheme tilts toward whichever question the designer trusts most. Two sites with identical pillar values can still produce different totals through this step alone.

What to do with the disagreement

Treat it as a prompt, not a problem. Find which of the four choices differs, and you will usually have learned something specific about the company: that it is strong against its sector but ordinary against the market, or that its latest quarter changed the picture. That is more useful than either score on its own.

Why the Same Company Can Score Differently in Two Classification Systems

A sector-relative score depends on one thing before any metric is read: which companies count as the peer group. Two research tools using two classification systems can put the same company in different neighbourhoods, and the scores that follow will disagree. Neither is wrong. They are answering the question against different comparison sets.

Where classifications disagree

A payments company can be labelled technology in one system and financials in another. A pharmacy chain can be retail or healthcare. A tower operator can be real estate or telecom. In each case the company's own numbers are identical, but its margins, leverage and growth are ranked against a different crowd, and the percentiles move.

Why one system has to be chosen and named

A score that does not say which classification it uses cannot be checked. The methodology has to name the system, the level of granularity, industry or sector, and the rule for companies that sit on a boundary. Once named, a reader can at least see what the company is being compared with and judge whether that comparison fits.

What to do when the label looks wrong

Read the raw metrics for the four or five companies you consider the true competitors, and rank by eye. Five companies can be compared by hand in a few minutes. If the hand comparison and the score disagree, the label is the likely cause, and the score should be read as describing a different neighbourhood than the one you had in mind.

Boundary companies are worth extra attention

A company on the edge of two sectors often has the economics of both, and the market may price it against whichever comparison set is in favour that year. Its score will swing with the label more than its business does. That is a reason to look at the components rather than a reason to distrust the method.

How Often Should You Re-Check a Stock Score? A Cadence That Matches the Data

Checking a stock score every day feels diligent and is mostly wasted. Four of the five pillars are built from quarterly filings and do not move between them. Checking it once a year misses the moments that matter. The right cadence follows the data, and the data has two speeds.

The slow speed: filings

Business quality, financial safety, valuation and growth durability all rest on reported financials. They change when a new quarterly report reaches the data feed, usually a few days to a few weeks after the company reports. Between filings they are static, apart from the valuation pillar drifting with price. Re-reading them weekly tells you nothing you did not know last week.

The fast speed: prices

Momentum is built from six and twelve month price change ranked inside the sector and moves daily. It is one pillar out of five, and it is deliberately slow-moving even so, because a six-month window does not turn on a single bad day.

A practical schedule

After each earnings season, read the four fundamental pillars for every company on your list. That is four sessions a year, and they are the ones that matter. Once a month, glance at momentum and at the total, mainly to catch a company whose sector-relative rank is diverging from its sector. Ignore the score between those points unless the company itself reports something.

The tell-tale of a stale score

Compare the calculation date with the company's most recent earnings date. If the score predates the report, it is describing the previous quarter and should be read as provisional until the feed catches up. That single check prevents most of the mistakes people make with dated numbers.

Momentum Against the Sector, Not the Index: Why the Benchmark Choice Changes the Answer

Most momentum screens measure a stock's price change against the broad index. A sector-relative score measures it against the stock's own sector. The two answers disagree more often than people expect, and the disagreement is the point.

What index-relative momentum hides

When a whole sector rallies, every stock in it shows strong momentum against the index, including the laggards. When a whole sector sells off, every stock in it shows weak momentum, including the leaders. Index-relative momentum is mostly a sector bet in disguise. It tells you which industry the market likes this quarter, which is useful, but it is not information about the company.

What sector-relative momentum shows

Ranking six-month and twelve-month price change inside the sector strips the sector move out. What remains is whether the market is treating this company better or worse than its direct competitors. A stock in the 90th percentile of its sector on momentum is being singled out by other investors for a reason, and that reason is usually visible in the fundamental pillars a quarter later.

Why it is the only price-based pillar

Four pillars are built from filings and move quarterly. Momentum is built from prices and moves daily. It is included because it is the fastest signal that other investors have noticed what the fundamentals show, and it is limited to one pillar out of five because price alone is the easiest signal to overfit.

Reading it in a selloff

A high-quality company selling off with its sector on no company news usually keeps a strong sector-relative momentum rank even while its index-relative momentum collapses. That divergence is the profile of a pullback rather than a breakdown. The reverse, a stock underperforming its sector while the sector rallies, is the profile worth checking for a company-specific problem.

Growth Durability: Why Three Years of Revenue Beats One Great Quarter

Growth is the pillar most people want to read first and the one most easily fooled by a single quarter. The growth durability pillar in a sector-relative score is built to resist that, and this post explains what it looks at and why.

Three years, not one quarter

The primary input is three-year revenue growth, ranked inside the sector. A company that grew forty percent last quarter off a weak comparison can look spectacular on a one-quarter view and ordinary on a three-year view. The longer window is less exciting and far more informative about whether the growth is a trend or an event.

Earnings growth against revenue growth

The second input compares earnings growth with revenue growth. Earnings outpacing revenue for several years usually means margin expansion, which is real but has a ceiling; a company cannot expand margins forever. Earnings lagging revenue for years usually means the growth is being bought with price cuts or spending. Neither is disqualifying, but each changes how durable the growth is likely to be.

Organic against acquired

Growth funded by acquisitions is a different animal from growth from the existing business. Where the data allows it, the pillar flags companies whose revenue growth is mostly acquired, because that growth stops the moment the acquiring stops and it usually arrives with debt that shows up in the financial safety pillar.

Why it is ranked inside the sector

Ten percent revenue growth is sleepy for a cloud company and remarkable for a packaged-food producer. Ranking inside the sector turns the same ten percent into a low percentile in one case and a high percentile in the other, which is the only way the number can be compared across the market.

Reading it with the other pillars

High growth durability with low business quality is a company growing without earning much on its capital; watch the margins. High growth durability with low financial safety is growth funded by leverage; watch the coverage. The pillar on its own is a fragment, which is why the five are shown side by side.
