❓ QUESTION:
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
"Why does Apple (AAPL) not have SEDAR+ filings?"

✅ ANSWER:
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
AAPL is a US company, so it files with SEC EDGAR (not SEDAR+)

🌎 FILING SYSTEMS BY COUNTRY:

  🇺🇸 SEC EDGAR (United States)
  ─────────────────────────────
  For:      US companies
  Regulator: US Securities and Exchange Commission
  Exchanges: NASDAQ, NYSE, CBOE
  Examples:  AAPL, MSFT, GOOGL, AMZN
  
  🇨🇦 SEDAR+ (Canada)

  ─────────── ───────── ────────── ──────────────── ─────
  AAPL        NASDAQ    🇺🇸 USA    SEC EDGAR        400 ✅
  MSFT        NASDAQ    🇺🇸 USA    SEC EDGAR        100 ✅
  SHOP.TO     TSX       🇨🇦 Canada SEDAR+           0   ⚠️

💡 WHY AAPL HAS 400 FILINGS (NOT 100):
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
  
  Regular Filings (100):
    • 10-K (Annual Reports)
    • 10-Q (Quarterly Reports)
    • 8-K (Current Events)
    • S-8, DEF 14A, etc.
  
  Insider Ownership Forms (300):
    • Form 3 (Initial Ownership)
    • Form 4 (Insider Transactions)
    • Form 5 (Annual Statement)
    • Forms 13D/13G (Large Holders)

🔍 SYSTEM LOGIC:

  Step 6 - SEC EDGAR Scraper:
  ┌─────────────────────────────────────────────┐
  │ IF exchange in ['NASDAQ', 'NYSE', 'CBOE']   │
  │ THEN scrape SEC EDGAR filings               │
  │                                              │
  │ ✅ AAPL → NASDAQ → SEC EDGAR (400 filings)  │
  │ ✅ MSFT → NASDAQ → SEC EDGAR (100 filings)  │
  └─────────────────────────────────────────────┘

  Step 7 - SEDAR+ Scraper:
  ┌─────────────────────────────────────────────┐
  │ IF exchange in ['TSX', 'TSXV', 'CSE']       │
  │ THEN scrape SEDAR+ filings                  │
  │                                              │
  │ ✅ SHOP.TO → TSX → SEDAR+ (attempted)       │
  │ ❌ AAPL → NASDAQ → Skipped (not Canadian)   │
  └─────────────────────────────────────────────┘

✅ VERIFICATION:
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

  Database Query:
  ───────────────
  SELECT symbol, COUNT(*), source 
  FROM filings f
  JOIN stocks_master s ON f.stock_id = s.id
  WHERE symbol = 'AAPL'
  GROUP BY source;

  Result:
  ───────────────
  AAPL | 400 | SEC EDGAR ✅

  Files on Disk:
  ───────────────
  data/sec_filings/AAPL_sec_filings.json       76 KB ✅
  data/sedar_filings/AAPL_sedar_data.json      NOT EXISTS ✓ (correct!)

🎯 SUMMARY:
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

  ✅ AAPL is a US company → Files with SEC EDGAR
  ✅ System correctly scraped 400 SEC filings for AAPL
  ✅ SEDAR+ is only for Canadian companies
  ✅ AAPL doesn't need SEDAR+ filings
  
  🎉 EVERYTHING IS WORKING CORRECTLY!
