## [2026-06-12] - Phase 3.0 Whale Satellite-Screener (#ISSUE-010)
|
||||
|
||||
### Added
|
||||
* **Whale Screener API Endpoint**: Created [/api/whale/screener/route.ts](file:///c:/Users/jannr/.gemini/antigravity/scratch/investment-sandbox/app/api/whale/screener/route.ts) which ingests SEC 13F filings for target CIKs: Scion (Michael Burry), Akre Capital, and Mairs & Power. Calculates relative portfolio weights and Velocity of Conviction (VoC) weight deltas between the last two quarters. Supports `DEV_MODE` offline short-circuit.
|
||||
* **Whale Screener UI Tab**: Deployed [WhaleScreener.tsx](file:///c:/Users/jannr/.gemini/antigravity/scratch/investment-sandbox/components/modules/whale/WhaleScreener.tsx) featuring a premium glassmorphic dark terminal with Whale Profile Cards on the left and a consolidated buy/sell ledger sorted strictly by highest positive VoC delta on the right.
|
||||
* **Whale Handbook Modal**: Deployed [WhaleMathModal.tsx](file:///c:/Users/jannr/.gemini/antigravity/scratch/investment-sandbox/components/modules/whale/WhaleMathModal.tsx) displaying full-screen explanations of the 45-day reporting lag and VoC equations in block LaTeX.
|
||||
|
||||
### Modified
|
||||
* **`app/page.tsx`**: Integrated the `[🐋 Whale Screener]` tab in the headers and switcher block.
|
||||
* **`QUANT_ROADMAP.md`**: Updated Section 1 and Section 3 to document the Whale Screener milestone.
|
||||
|
||||
### Active Bugs / Compile Status
|
||||
* **Active Bugs**: None.
|
||||
* **Type Checker Status**: Verified clean compilation (`npx tsc --noEmit` returns exit code 0).

3. **Co-ownership Clusters**: Identify stocks bought by 3 or more selected boutique managers simultaneously.
|
||||
|
||||
### Implemented Architecture
|
||||
- **API Endpoint**: [/api/whale/screener](file:///c:/Users/jannr/.gemini/antigravity/scratch/investment-sandbox/app/api/whale/screener/route.ts) fetches SEC Form 13F filings for Scion Asset Management (Michael Burry: `0001649339`), Akre Capital Management (`0001483348`), and Mairs & Power Small Cap Fund (`0001099684`).
|
||||
- **Offline Fallback**: Respects `DEV_MODE=true` environment configurations, completely bypassing outbound FMP requests and serving structured `MOCK_WHALE_DATA` with `isShieldActive: true`.
|
||||
- **Velocity of Conviction**:
|
||||
$$\text{VoC}_i = w_{i, t} - w_{i, t-1}$$
|
||||
$$w_{i, t} = \frac{V_{i, t}}{\sum_{j} V_{j, t}} \times 100$$

The Whale Satellite Screener isolates high-conviction adjustments in portfolios managed by elite long-term value and small-cap investment firms (such as Michael Burry's Scion Asset Management and Chuck Akre's Akre Capital). By calculating the quarter-over-quarter relative portfolio weight adjustments, the system tracks the directional commitment ("Velocity of Conviction") of smart capital while adjusting for reporting lags and sector clustering.

|

</h4>
|
||||
<p className="text-xs leading-relaxed text-slate-400">
|
||||
Institutional investment managers with over $100 million in Assets Under Management (AUM) are legally mandated by the SEC to submit Form 13F within 45 days after the end of each calendar quarter. This lag presents a structural challenge for quantitative models, as holdings data represents historical positions:

|
||||
<div>
|
||||
<strong className="text-blue-300 block mb-1">I. Retrospective Analysis:</strong>
|
||||
Positions disclosed on day \(T + 45\) reflect the portfolio state at day \(T\). As a result, short-term momentum models cannot directly trade 13F filings.
|
||||
</div>
|
||||
<div>
|
||||
<strong className="text-blue-300 block mb-1">II. Informational Asymmetry:</strong>
|
||||
Because holdings are backward-looking, the screener is optimized for long-term fundamental tracking (holding periods exceeding 12 months) where the 45-day lag does not dilute the underlying investment thesis.

|
||||
</h4>
|
||||
<p className="text-xs leading-relaxed text-slate-400">
|
||||
Rather than tracking the absolute number of shares bought or sold, the screener measures changes in the relative portfolio weight of each asset. This normalizes for AUM changes caused by overall market movements:

||||

|
||||
<div className="bg-slate-955/40 p-5 rounded-2xl border border-slate-850 my-2 space-y-4">

Where:
|
||||
<br />
|
||||
- <InlineMath math="w_{i, t}" /> is the portfolio weight of asset \(i\) at the end of the current quarter \(t\) (expressed as a percentage).
|
||||
<br />
|
||||
- <InlineMath math="w_{i, t-1}" /> is the portfolio weight of asset \(i\) at the end of the previous quarter \(t-1\).
|
||||
<br />
|
||||
- <InlineMath math="V_{i, t}" /> is the market value of the position in asset \(i\) as reported in the 13F filing for quarter \(t\).
|
||||
<br />
|
||||
- <InlineMath math="\sum_{j} V_{j, t}" /> represents the total market value of all reported equity holdings in the filing for quarter \(t\) (AUM proxy).

|

</div>
|
||||
<p className="text-xs leading-relaxed text-slate-400">
|
||||
<strong className="text-blue-300">Strategic Rationale:</strong> A positive VoC delta {"\\(\\text{VoC}_i > 0\\)"} indicates that the manager has actively allocated capital to the asset relative to other holdings, suggesting high-conviction buying. Conversely, a negative delta {"\\(\\text{VoC}_i < 0\\)"} indicates relative allocation decreases, showing active selling or profit-taking.

|
||||
</h4>
|
||||
<p className="text-xs leading-relaxed text-slate-400">
|
||||
Institutional clustering occurs when multiple high-conviction managers establish positions in the same security during the same period. The screener tracks cross-ownership patterns to detect when elite managers converge on specific investment clusters, which historically serves as a strong signal of structural undervaluation.
