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
Are earnings accelerating?

The latest quarter must be more than 25% above the prior-year quarter: growth now, not someday.

02
Does the growth carry over years?

The long-term earnings trend (5-year CAGR above 25%) separates flashes in the pan from real growth machines.

03
Does the market confirm the story?

A price near the 52-week high and relative strength above +15% show institutional money moving in.

04
Is volume coming along?

Rising prices on rising volume, otherwise the breakout lacks conviction.

For whom

Who is this strategy for?

For aggressive investors with high volatility tolerance and the discipline to sell losers quickly. Momentum strategies live on rigorous risk management: the deduction for prices deep below the 52-week high is the built-in ripcord.

FAQ

Frequently asked questions

Is this based on CAN SLIM by William O'Neil?
The strategy implements the quantifiable core of the CAN SLIM system: C, A, N, S and L with documented data proxies; the qualitative criteria I and M are omitted. StockScorer has no affiliation with the trademark owner.
Why buy stocks near the high instead of on the dip?
Because new highs statistically lead to further highs more often than lows lead to recoveries: a stock at its 52-week high has no frustrated overhead holders selling into every rally. That is exactly the effect the strategy exploits.
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 lower the growth thresholds?
Yes. After free registration you can copy the profile and adjust it in the rule editor: the 25% hurdles, the high-distance and all point values are fully configurable.

More on the methodology

Method & Criteria

Growth Momentum looks for the most dynamic stocks in the market just before or during their breakout. The model is William O'Neil's CAN SLIM system, based on a study of the strongest price winners across several decades: explosive earnings growth in the latest quarter (C) and over years (A), a price near the 52-week high (N), rising trading volume (S) and market leadership in relative strength (L). The approach deliberately runs contrary to value investing: you buy strength expecting trends to continue, not weakness hoping for recovery.

How does Growth Momentum work?

Five criteria earn one point each: quarterly earnings growth above 25% versus the prior-year quarter (C), long-term earnings growth above 25% per year (A), a price at most 5% below the 52-week high (N), rising trading volume with positive 3-month performance (S) and a 6-month relative strength of more than +15% versus the market (L). If a stock trades more than 30% below its 52-week high, that costs 2 points: a broken trend disqualifies.

The upper threshold is 3 points for large caps, 4 for mid caps and 5 for small caps: a small cap therefore has to meet all five criteria at once. That is intentional: the most explosive breakouts happen in smaller names, but that is also where the noise is loudest.

The criteria at a glance

C: Current earnings, earnings growth in the latest quarter > 25% YoY (+1).

A: Annual earnings, earnings growth over 5 years > 25% p.a. (+1).

N: New highs, price at most 5% below the 52-week high (+1).

S: Supply & demand, 3-month volume rising with a positive price (+1).

L: Leader, 6-month relative strength > +15% versus the market (+1). Price > 30% below the high: −2.

Strengths, limits and deviations from the original

Documented deviations: long-term growth is measured via the 5-year CAGR (original: 3 years), market leadership via 6-month relative strength instead of RSI(14), and volume via the 3-month trend instead of the 50-day average. The original criteria I (institutional buyers) and M (market direction) are dropped for lack of data. Thresholds are lowered accordingly by the two dropped points.

In the backtest, the quarterly-earnings and volume criteria are neutralised for lack of historical data points; 52-week high, relative strength and long-term growth are reconstructed historically. The rule-coverage panel in the backtest scales the thresholds proportionally and discloses this transparently.

Who is this strategy for?

For trend-oriented investors who accept shorter holding periods and manage positions rigorously by score: momentum rewards discipline, not patience.
