Methodology

How the scoring works

Every stock runs through the same disclosed rules. The points add up to a score, traceable down to the individual rule.

01
Rules

Each rule checks a metric against a threshold, for example ROE above 15 %.

02
Points & weighting

You decide how much each rule counts: from +1 to +3 or −1 to −3.

03
Score & classification

The sum is the score. Above the upper threshold: a high match with the profile.

Low matchMedium matchHigh match
low scorelower thresholdupper thresholdhigh score

These terms describe only the match with the criteria, not a recommendation to buy or sell.

The strategy

What is behind this strategy?

01
Is the profit backed by cash?

The Sloan ratio compares book profit with actual cash flows: the core question of earnings quality.

02
How large is the bookwork share?

Below −10% excellent (+2), −10 to +10% healthy (+1), from +10% the warning zone begins.

03
Is a reversal coming?

High accruals historically reverse: aggressive bookings are followed by weak subsequent years.

04
Is the accounting creative?

Values above +25% point to pulled-forward revenues or deferred costs: extreme danger (−3).

For whom

Who is this strategy for?

For fundamental investors as a quality filter over any earnings-based strategy: a low P/E is worthless if the "E" in it is mere bookwork. Particularly valuable before buying after strong earnings jumps.

FAQ

Frequently asked questions

Is this based on Richard Sloan's research?
Yes, the accrual anomaly was demonstrated by Richard Sloan in 1996: companies with high accruals systematically delivered weaker subsequent returns. StockScorer implements the Sloan ratio as an automated zone system.
Is a strongly negative Sloan ratio always good?
Usually yes: it shows more money actually flowing than the profit reports, for instance through high non-cash depreciation. Extremely negative values can, however, also point to massive one-off write-downs; a look into the report remains worthwhile.
Is this a buy recommendation?
No. StockScorer provides automated, rule-based assessments for information only. Nothing here replaces individual financial advice or constitutes a solicitation to buy or sell securities.
Can I adjust the zone boundaries?
Yes. After free registration you can copy the profile and modify it in the rule editor: zone boundaries and point values are fully configurable.

More on the methodology

Method & Criteria

The accrual anomaly is one of the most robust findings in accounting research: Richard Sloan showed in 1996 that investors fixate on reported net income ("earnings fixation") and overlook how much of it is mere bookwork. Accruals (non-cash profit components such as pulled-forward revenues or deferred costs) reverse over time. The Sloan ratio measures their share: (net income − operating cash flow − investing cash flow) relative to total assets. Strongly negative values mean overflowing tills with an accounting-wise understated profit; values above +25% signal extreme danger: manipulation or impending write-downs.

How does the accrual check work?

The Sloan ratio is calculated as (net income − operating cash flow − investing cash flow) divided by average total assets. A value below −10% means excellent cash coverage (+2): the company really earns more than the income statement shows, typical with high non-cash depreciation. The zone from −10 to +10% counts as healthy (+1).

From +10% the warning level begins (−1): a growing share of profit is not covered by payments. Above +25% extreme danger prevails (−3): such values arise from aggressive receivables booking, pulled-forward revenues or costs pushed into the future. The upper threshold is 1 point (small caps: 2); without a computable Sloan ratio the classification stays neutral in the middle.

The zones at a glance

Sloan ratio < −10%: excellent cash coverage, cash flow clearly exceeds book profit (+2).

−10 to +10%: healthy zone, profit and cash flows match (+1).

+10 to +25%: warning level, high share of book profits (−1).

≥ +25%: extreme danger, indication of manipulation or impending write-downs (−3).

Strengths and limits

The strength: the check is a pure cash-flow reconciliation and thus hard to dress up: whoever pulls revenues forward cannot book the missing cash flow into existence. As a cross-check for any earnings-based metric (P/E, ROE, EPS growth) it exposes when their foundation wobbles. The StockScorer Score uses exactly this check as a knockout gate.

Limits: single years can be distorted by legitimate one-offs (acquisitions, large projects, working-capital build-up before expansion); a high value is a prompt to investigate, not a verdict. The strategy also measures quality only, not valuation or growth; it unfolds its value above all in combination.

Who is this strategy for?

For sceptical fundamental investors who want to cross-check earnings quality systematically, as a filter over watchlists, before adding to positions, and over any strategy built on reported profits.
