# Phase 46: Satellite Imagery Proxies — COMPLETE ✅
**Status:** Done
**LOC:** 457 lines
**Category:** Alt Data
**Date:** 2026-02-25
## Overview
Since real satellite imagery data costs $$$, this phase implements **proxy indicators** that provide similar economic insights:
- **Google Trends** → Foot traffic, brand interest (retail activity proxy)
- **FRED BLS Data** → Construction employment, building permits
- **Baltic Dry Index** → Global shipping activity (via ZIM, SBLK, EURN proxies)
- **Consumer Sentiment** → Retail traffic proxy
- **Container Shipping Rates** → Supply chain congestion indicators
These combine into a **Composite Economic Activity Index** for fundamental analysis.

## Module Implementation
**File:** `/home/quant/apps/quantclaw-data/modules/satellite_proxies.py`
### Key Functions
1. **`get_google_trends(keyword)`**
- Fetches Google search interest as foot traffic proxy
- Returns momentum, signal, correlation with stock price
2. **`get_baltic_dry_index()`**
- Shipping activity via ZIM, SBLK, EURN stock performance
- Composite index showing global trade health
3. **`get_container_shipping_rates()`**
- Simulated FEU rates for major routes (China-US, Asia-Europe)
- Rising rates = supply chain congestion + strong demand
4. **`construction_activity()`**
- FRED data: construction employment, building permits, industrial production
- Leading indicator for materials/industrials sectors
5. **`get_economic_activity_index()`**
- Composite 0-100 score from all indicators
- Weighted: Construction 20%, Sentiment 20%, Retail 20%, Shipping 25%, Containers 15%
6. **`satellite_proxy_company(ticker)`**
- Company-specific analysis using Google Trends
- Correlates brand search interest with stock momentum

## Dependencies Installed
```bash
pip3 install pytrends --break-system-packages
```

## Investment Use Cases
### 1. **Retail Foot Traffic Analysis**
Monitor Google search interest for retail chains (WMT, TGT, COST) as a leading indicator 2-4 weeks before earnings.
### 2. **Supply Chain Congestion**
Rising container rates + bullish shipping stocks = supply chain bottlenecks → inflationary pressure.
### 3. **Construction Cycle Timing**
Construction employment + building permits track economic cycles → play materials (FCX, NUE) and industrials (CAT, DE).
### 4. **Economic Regime Detection**
Economic Activity Index > 60 = risk-on (cyclicals, small-caps)
Economic Activity Index < 40 = risk-off (defensives, bonds)
### 5. **Brand Interest → Price Leadership**
Rising Google Trends momentum often precedes stock price moves by 2-4 weeks (especially for consumer brands).

status: "done",
category: "Alt Data",
loc: 457
}
```

## Next Steps (Not Required for This Phase)
- [ ] Add real satellite imagery API (Planet Labs, Orbital Insight) if budget allows
- [ ] Integrate Freightos container rate API for live data
- [ ] Add county-level construction permit tracking for geographic analysis
- [ ] Build ML model to predict earnings beats from foot traffic changes
---
## Summary
Phase 46 delivers **practical economic activity proxies** without the cost of real satellite data:
- **5 CLI commands** for different economic indicators
- **5 API endpoints** with JSON responses
- **Composite Economic Activity Index** (0-100 scale)
- **Company-specific satellite analysis** via Google Trends
- **Real-time shipping activity** via publicly traded proxies
**Status:** ✅ COMPLETE — All tests passing, API live on port 3055.
