How to Read a Growth Score Correctly

The Growth score answers a more specific question than "is this company growing" — it asks whether that growth is steady, whether it holds up against what the sector typically manages, and whether it's speeding up or slowing down over time.

📘 What Does the Growth Score Measure?

The Growth score is built from profit CAGR measured over two different time windows, plus a check on whether growth is accelerating or decelerating. The exact breakdown, out of 100 points: the primary, long-run profit CAGR contributes 50 points, measured against the sector's typical growth rate rather than a fixed universal bar. The 3-year CAGR contributes 30 points, also sector-relative. The remaining 20 points come from an acceleration check — specifically, whether the 3-year CAGR is running faster than the long-run rate, which would suggest growth is speeding up rather than settling into a slower, more mature pace.

Growth = Primary CAGR (50) + 3yr CAGR (30) + Acceleration (20) ± Alignment adjustment
Primary (long-run) profit CAGR, vs sector's growth bar50 pts
3-year profit CAGR, vs sector's growth bar30 pts
Acceleration — is 3yr CAGR faster than the long-run rate?20 pts

Then a Profit vs Revenue Alignment adjustment of roughly ±3 to ±6 points, described in more detail below.

See How Our Scores Work for the exact formula and weighting used, including the alignment adjustment.

🎯 Why This Matters

A single growth number, taken from one time window, can be genuinely misleading — a strong 3-year CAGR sitting on top of a much weaker long-run trend tells a very different story than the same 3-year figure representing a genuine, sustained acceleration. By deliberately weighing both a long-run and a shorter-run measure against each other, the Growth score captures the trajectory, not just a snapshot.

This matters because the market tends to reward accelerating growth more generously than merely steady growth at the same absolute rate — a business whose growth is genuinely speeding up is telling a different, often more valuable and durable story than one that's simply maintaining a stable pace year after year.

📖 How to Read the Growth Score

  • 0–49. Weak — profit growth is running behind the sector's typical pace, or has been flat or declining.
  • 50–69. Moderate — growth roughly in line with what's typical for the sector.
  • 70–84. Strong — growth comfortably ahead of the sector norm, often with signs of acceleration.
  • 85–100. Excellent — growth well ahead of sector peers across both time windows, with genuine acceleration.

A further adjustment — the Profit vs Revenue Alignment check, worth roughly ±3 to ±6 points — penalizes profit growth that's been running meaningfully ahead of revenue growth for too long, since this usually reflects margin expansion running out of room to continue rather than durable, sustainable strength going forward.

🧭 When to Use the Growth Score

The Growth score is most useful when:

  • Screening for companies with genuine momentum. The acceleration component specifically surfaces businesses whose growth is speeding up, not just continuing at a flat pace.
  • Comparing growth across companies fairly. Since it's measured against sector norms, a strong Growth score means something comparable whether the company is in a naturally fast-growing sector or a slower, more mature one.
  • Checking whether recent strong performance is part of a longer trend. By weighing both a long-run and short-run window, the score resists being fooled by one unusually good recent year.

🏭 How Cyclical And New Companies Are Handled

Two situations get special treatment rather than being forced through the standard formula. Cyclical businesses — where profit naturally swings up and down with a broader commodity or industry cycle — use a cycle-averaged growth calculation instead of raw year-over-year figures, so that landing on an unusually strong or weak point in the cycle doesn't distort the result.

Companies with a recent latest-year loss, or too little trading history for a full CAGR calculation (recently listed companies), each use a separate calculation built specifically for that situation, rather than being forced through a formula that assumes data these companies simply don't have yet.

⚖️ Comparison With Related Pillars

  • Growth vs Earnings Quality. Growth measured purely on reported profit can be misleading if that growth isn't backed by genuine cash generation — a strong Growth score paired with a weak Earnings Quality score deserves a closer look before trusting the growth story fully.
  • Growth vs Opportunity. Growth measures what a company has already achieved; Opportunity looks forward, asking how much room remains to keep growing — a company can score well on one and modestly on the other.
  • Growth vs Valuation. A high Growth score paired with an already very expensive valuation means much of that growth may already be priced in — the two are meant to be read together, not independently.
  • Growth vs Profitability. A company can be growing rapidly while still building toward strong profitability, or already highly profitable while growing modestly — the two pillars capture genuinely different, complementary aspects of a business's trajectory.

🧮 Real Examples

1Genuine, accelerating growth

"Northbridge Software" (illustrative) posted a long-run profit CAGR of 18%, well ahead of its sector's typical 12%, and a 3-year CAGR of 24% — meaningfully faster than its own long-run rate. No meaningful profit vs revenue gap, so no alignment penalty applies:

Primary CAGR: 44/50 · 3yr CAGR: 27/30 · Acceleration: 18/20 · Alignment: +0 Total = 44 + 27 + 18 + 0 = 89

This combination of strong sector-relative growth on both time windows, plus genuine acceleration earning nearly full marks on that component, produces a score that reflects real, broad-based momentum rather than one flattering figure alone.

2Strong recent growth that isn't accelerating

"Coastal Pharma" (illustrative) shows a 3-year CAGR of 20% — an impressive figure on its own — but its long-run CAGR is a similar 19%, meaning growth is steady rather than genuinely speeding up:

Primary CAGR: 40/50 · 3yr CAGR: 23/30 · Acceleration: 6/20 · Alignment: +0 Total = 40 + 23 + 6 + 0 = 69

Both CAGR components score comfortably, reflecting genuinely strong growth in absolute terms. But because the recent pace isn't meaningfully outrunning the long-run trend, the Acceleration component — worth 20 points on its own — contributes only a small fraction of what it could, pulling the combined total down from what a first glance at either CAGR figure alone might suggest.

3Profit growth outrunning revenue

"Ironclad Distributors" (illustrative) shows profit CAGR significantly ahead of its own revenue CAGR, sustained over several years — a pattern the Profit vs Revenue Alignment check specifically flags:

Primary CAGR: 41/50 · 3yr CAGR: 25/30 · Acceleration: 14/20 · Alignment: −6 Total = 41 + 25 + 14 − 6 = 74

Without the alignment adjustment, this would have been a genuinely strong score around 80. The −6 penalty reflects the real possibility that continued margin expansion, not genuine underlying business strength, is driving the profit growth figure — exactly the kind of nuance a raw CAGR number alone wouldn't surface.

🚫 Common Mistakes When Reading This Score

  • Judging growth against a fixed number instead of the sector. What counts as strong growth varies enormously by industry — the score already accounts for this, but it's worth understanding why.
  • Treating a high Growth score as proof the growth is genuine. Always check Earnings Quality alongside it, since reported profit growth isn't automatically backed by real cash.
  • Assuming a lower score for a mature, stable company is a weakness. Some genuinely excellent businesses have simply matured past their fastest growth phase — this pillar measures growth specifically, not overall quality.

⚠️ Limitations of the Growth Score

  • Backward-looking. Built from historical reported growth — it describes past trajectory, not a guarantee of future growth continuing at the same pace, however strong that past pace has been.
  • Doesn't capture the source of growth. Organic growth from genuine business expansion and growth from a large acquisition can look similar in a CAGR figure, despite being very different in character and durability.
  • A single accounting adjustment can distort a CAGR window. Though the alignment and cyclical adjustments described above help reduce this risk.

❓ Frequently Asked Questions

Why does IsStockSafe use two different CAGR windows instead of one?

Because a single window can be misleading — a strong recent period sitting on top of a much weaker long-run trend, or vice versa, tells a genuinely different story than either window alone. Weighing both together, and specifically checking whether one is outrunning the other, captures the trajectory rather than a single snapshot.

How are recently listed companies scored on Growth?

Companies without enough trading history for a full CAGR calculation use a separate approach built specifically for limited data, rather than being forced through the standard formula with data they don't yet have.

Why would a fast-growing company still get a moderate Growth score?

Growth is measured against the company's own sector, not a universal benchmark — a growth rate that looks impressive in absolute terms can be fairly ordinary for a sector where that pace is typical, especially without genuine acceleration on top of it.

How does the Growth score handle a cyclical company?

Rather than using raw year-over-year figures, which can land at very different points in the cycle depending purely on timing, cyclical businesses are scored using a cycle-averaged growth calculation — smoothing out the natural ups and downs so the score reflects the underlying trend rather than wherever the company happened to sit in its cycle at measurement time.

Can a company with declining profit still get a positive Growth score?

A company with negative or declining profit growth would score toward the low end of the range, though the exact treatment depends on the specific pattern — a company recovering from a recent loss, for example, uses a separate calculation designed for that situation rather than the standard CAGR-based formula, which doesn't work cleanly when the starting figure was negative.

📌 Key Takeaways

  • The Growth score weighs long-run CAGR (50 points), 3-year CAGR (30 points), and acceleration (20 points), each measured against sector norms.
  • Acceleration — whether recent growth is outrunning the long-run trend — is rewarded specifically, not just growth itself.
  • A Profit vs Revenue Alignment check penalizes profit growth that's outrunning revenue growth for too long.
  • Cyclical and recently listed companies use adjusted calculations built for their specific situation.
  • Always read Growth alongside Earnings Quality and Valuation for a complete picture.
