AI Infrastructure Index Methodology
How the InvestorLens AI Infrastructure Index score is calculated and what it represents.
AI Infrastructure Index Methodology
The InvestorLens AI Infrastructure Index is a proprietary composite score (0–100) tracking the health and momentum of the AI datacenter supply chain as reflected in public filing data.
It is an educational indicator only — not a financial index, not investable, and not a recommendation.
Index Score Calculation
The index score is the weighted average of all 20 tracked companies' Theme Scores, weighted by each company's individual theme score.
Index = Weighted average of Theme Scores across all 20 companies
Theme Score Components
Each company's Theme Score is a weighted composite of four sub-scores:
| Component | Weight | Data Source |
|---|---|---|
| Institutional Score | 35% | 13F holdings + holding changes |
| Insider Score | 25% | Form 4 filings (proxy until live data) |
| Billionaire Score | 20% | 13F holdings from high-profile investors |
| Momentum Score | 20% | Recent accumulation activity patterns |
Institutional Score (35%)
Derived from InvestorLens's 13F database:
- Investor count: Number of tracked investors currently holding the stock (50% weight)
- Position value: Total reported market value across tracked investors (30% weight)
- Net direction: Whether recent changes skew toward accumulation or reduction (20% weight)
Momentum Score (20%)
Derived from recent holding changes:
- NEW positions score 3x
- INCREASED positions score 1.5x
- REDUCED positions score -1.5x
- SOLD OUT positions score -3x
- Changes within 90 days receive full weight; older changes receive 50% weight
Billionaire Score (20%)
Derived from holdings data for tracked high-profile investors. Computed as a blend of institutional score with a momentum adjustment.
Insider Score (25%)
Currently computed as a proxy using recent accumulation activity. Will be replaced with real SEC Form 4 data in a future update.
Sentiment Classification
| Score Range | Sentiment |
|---|---|
| 72 – 100 | BULLISH |
| 55 – 71 | NEUTRAL |
