Worked Example — Verifies Today's #1 Score
We re-compute today's top-ranked stock factor by factor. The composite must reconcile to the displayed score within ±0.5. If it doesn't, the model is broken — please report it.
Red Flag Rules
Red flags annotate tickers; they do not remove them from the basket. Quality Growth uses flags that are structural (hard) or relative to today's basket (soft), because high P/E is normal for quality growers — a fixed P/E > 40 threshold would mis-fire on NVDA-class names.
Hard flags (structural)
• FCF Margin < 0 — company burns cash; incompatible with "quality grower" thesis.
• D/E > 3 — extreme leverage; balance sheet risk outweighs growth signal.
Soft flags (relative to today's basket)
• P/E above basket 75th percentile — relatively expensive even among quality growers.
• RSI(14) > 75 — technically overbought; short-term mean-reversion risk.
• EPS growth < 0 — bottom line shrinking while top line grows; dilutive or margin-pressured.
6-Factor Quality Growth Model
This screener evaluates US large-cap stocks (market cap > $5B) using a composite scoring system that balances cash-flow quality with growth momentum. Each stock receives a score from 0 to 100 based on six fundamental factors. The model prioritizes cash-flow quality (45% combined weight) over pure growth (30%), reflecting the empirical finding that quality factors tend to outperform over full market cycles.
The screener produces a daily basket of the top 40 names. The basket composition shifts day-to-day as scores re-rank — the Movers tab tracks who joins, leaves, gains, and slips.
Config Schema
• Universe — US large-cap, top 250 by market cap
• Factors — 6 (see Factor Weights below)
• Weights — FCF 25 · RevG 20 · ROIC 20 · P/E 15 · EPS 10 · D/E 10 (sum = 100)
• Direction — FCF ↑ · RevG ↑ · ROIC ↑ · P/E ↓ · EPS ↑ · D/E ↓; composite always ↑ = better
• Pass threshold — score ≥ 50 (soft filter; shown but flagged if below)
• Basket size — 40 (top-by-score after pass filter)
• Top N Focus — 5 (deterministic top-by-score; no editorial curation)
• Score bands — 80+ Elite · 70–79 Strong · 60–69 Average · <60 Weak
Selection Chain
The pipeline is deterministic — no human curation between the feed and the page:
universe (250 by mcap) → factor pull & filter (require FCF, RevG, ROIC) → score (0–100) → rank by score desc
→ Full Rankings = all scored names
→ Ranked list = top 40 (basket size)
→ Top 5 Focus = top 5 of ranked list
Scoring Formula
Each factor is normalized to a 0-to-max-weight scale. For "more is better" factors (FCF, Revenue Growth, ROIC, EPS Growth), values are linearly scaled against an empirical range. For "less is better" factors (P/E, D/E), values are inversely scored. All factor scores are capped at their maximum weight to prevent any single factor from dominating.
FCF Score = min(25, fcfMargin / 40% × 25)
RevG Score = min(20, revGrowth / 50% × 20)
ROIC Score = min(20, roic / 30% × 20)
P/E Score = max(0, (1 − (pe − 5) / 35)) × 15
EPS Score = min(10, (epsG + 20%) / 120% × 10)
D/E Score = max(0, (1 − de / 3)) × 10
Composite = FCF + RevG + ROIC + P/E + EPS + D/E
Factor Descriptions
FCF Margin (25%)
Free Cash Flow as a percentage of revenue. Measures how efficiently a company converts revenue into cash. Higher margins indicate pricing power and operational efficiency. Range: 0–40%+ (capped).
Revenue Growth (20%)
Year-over-year revenue growth rate. Captures top-line momentum and market share expansion. Range: 0–50%+ (capped).
ROIC (20%)
Return on Invested Capital. Measures management's ability to allocate capital and generate returns above cost of capital. A hallmark of durable competitive advantage. Range: 0–30%+ (capped).
Valuation — P/E Ratio (15%)
Price-to-Earnings ratio scored inversely. Penalizes extreme overvaluation while allowing premium multiples for quality growers. Sweet spot: 10–25x. Scores zero above 40x.
EPS Growth (10%)
Earnings per share growth rate. Confirms revenue growth translates to bottom-line expansion. Distinguishes profitable growth from revenue-buying. Range: -20%–100% (capped).
Balance Sheet — D/E (10%)
Debt-to-Equity ratio scored inversely. Favors companies with conservative leverage. Lower debt provides resilience during downturns. Scores zero above 3.0x.
What This Screen Does Not Capture
- Forward guidance, management commentary, and qualitative business-model shifts
- Institutional and insider positioning changes (covered by separate Alva SDKs)
- Macro regime sensitivity — the screen does not adjust for rate cycles or recession probability
- Sector-specific risk factors such as regulatory changes, patent cliffs, or commodity price shocks
- Market timing — the screen identifies quality, not optimal entry points
- Earnings surprises and estimate revisions between quarterly reports
