How Sector Calibration Works
A scoring system that applies identical metrics to a software company and a bank is fundamentally broken. Banks carry 10:1 leverage by design — flagging them for “high debt” is like flagging an airline for owning planes. REITs report depreciation that makes their earnings look artificially low. Utilities have regulated returns that cap both upside and downside. AlphaStocks solves this with seven sector-specific scoring profiles that adapt every model to the financial realities of each business type.
Why One-Size-Fits-All Scoring Fails
Financial analysis relies on comparing companies against benchmarks. But the right benchmark for a bank (Tier 1 capital ratio, net interest margin) is completely different from the right benchmark for a technology company (R&D efficiency, revenue growth). When a screener uses the same P/E threshold for a utility and a SaaS company, it produces misleading signals in both directions: utilities look “cheap” (low P/E is normal for regulated returns) while tech stocks look “expensive” (high P/E reflects high growth expectations).
The same problem affects financial health metrics. A debt-to-equity ratio of 1.5 is conservative for a bank but alarming for a software company. A current ratio below 1.0 is distress for a manufacturer but meaningless for an insurer (whose liabilities are insurance claims, not trade payables). Without sector calibration, these structural differences contaminate every score.
Seven Sector Profiles (v22)
AlphaStocks classifies every stock in its 1,595-stock universe into one of seven scoring profiles. Most companies use the General profile. Companies in specialized sectors receive dedicated profiles that adjust axis weights and model parameters.
| Profile | Quality | Value | Momentum | Timing |
|---|---|---|---|---|
| General | 40% | 10% | 35% | 15% |
| Bank | 45% | 10% | 30% | 15% |
| REIT | 35% | 15% | 35% | 15% |
| Insurer | 45% | 10% | 30% | 15% |
| Utility | 40% | 15% | 30% | 15% |
| Holding | 45% | 10% | 30% | 15% |
| Asset Manager | 45% | 10% | 30% | 15% |
What Each Profile Changes
Bank Profile
Banks require the most extensive adaptations. The Quality axis weight increases to 45% because a bank's balance sheet health is paramount — a weak bank can fail catastrophically. Within Quality, the Buffett model receives 75% weight (vs 65% general) because a bank's competitive moat comes from its deposit franchise, brand trust, and relationship network, not from manufacturing efficiency.
Piotroski adaptations: Current ratio is replaced with Tier 1 capital adequacy. Asset turnover is replaced with net interest margin trend. Debt-to-assets threshold is adjusted for banking leverage norms.
Graham fair value: Uses tangible book value adjusted for loan-loss reserves instead of the standard earnings-based Graham Number. Banks are valued on their asset base, not their earnings multiple.

REIT Profile
REITs (Real Estate Investment Trusts) report large depreciation charges on their properties, making traditional net income misleading. The REIT profile replaces net income with FFO (Funds From Operations) throughout all models.
The Value axis weight increases to 15% (from 10%) because REITs are income vehicles where valuation relative to cash flow generation matters more than for growth stocks. Within Value, the Lynch PEG model receives 40% weight (vs 25% general) to capture dividend-adjusted growth rates.
Quality axis: Weight decreases to 35% because REIT quality is more about portfolio and tenant diversification (captured via Buffett at 80% within Quality) than traditional manufacturing metrics.

Utility Profile
Utilities operate in regulated markets with predictable but capped returns. The Utility profile increases the Value axis weight to 15% because valuation discipline matters more when growth is limited. Momentum weight decreases to 30% because utility prices move slowly — penalizing them for low momentum would permanently suppress their composite scores.
Graham fair value: Uses regulated P/E with a dividend yield floor, reflecting the reality that utility investors primarily care about yield and payout stability.

Insurer, Holding, Asset Manager Profiles
These three profiles share the same axis weights (Quality 45%, Value 10%, Momentum 30%, Timing 15%) but differ in model-level adaptations. Insurers adjust the Piotroski F-Score for insurance float and underwriting reserves. Holding companies use diversified revenue stream analysis. Asset managers use AUM-driven revenue models and earnings power anchored to book value.
All three increase Quality weight to 45% because the financial complexity of these businesses makes fundamental strength the most important investment factor.
How Calibration Affects Scores
Without calibration, banks would systematically score low on financial health (because of leverage), REITs would score low on profitability (because of depreciation), and utilities would score low on momentum (because of slow price movement). Calibration corrects these structural biases.
The result is a composite score that is comparable across sectors. A bank scoring 7.5 and a tech stock scoring 7.5 are both in the “Buy” range, and both earned that rating against benchmarks appropriate to their business model. This is what makes the screener and rankings meaningful across the entire 1,595-stock coverage universe.
Each stock page on AlphaStocks displays its sector profile, so you can always see which calibration is being applied. The methodology page provides the full technical specification of each profile.
