## 🎯 QUESTIONS ANSWERED

### Question 1: Why "Imported 0 stocks"?

**Answer:** ✅ **This is CORRECT behavior!**

The database already contains 23 stocks from previous runs:
```sql
SELECT COUNT(*) FROM stocks_master;
-- Result: 23 stocks already imported
```

The system uses `INSERT OR IGNORE` which means:
- Existing stocks → Skip (prevent duplicates)
- New stocks → Insert

**Verification:**
```bash
sqlite3 data/stocks.db "SELECT symbol FROM stocks_master;"
```

**Result:**
- AAPL, MSFT, SHOP.TO ✅
- 20 CSE stocks (T2AAA, T2AABND, etc.) ✅

---

### Question 2: Why do some metrics show `null`?

**Answer:** ⚠️ **Data Source Limitation (Not a Bug!)**

6 out of 44 metrics show `null` because Yahoo Finance doesn't provide the required data:

| Metric | Required Data | Available? | Workaround |
|--------|---------------|------------|------------|
| Interest Coverage | Interest Expense | ❌ No | Parse SEC 10-K |
| Inventory Turnover | Inventory Balance | ❌ No | Parse Balance Sheet |
| Receivables Turnover | Accounts Receivable | ❌ No | Parse Balance Sheet |
| Payables Turnover | Accounts Payable | ❌ No | Parse Balance Sheet |
| Net Income Growth YoY | Historical Net Income | ❌ No | Scrape Multiple Years |
| Book Value Growth YoY | Historical Book Value | ❌ No | Scrape Multiple Years |

**This is acceptable because:**
- ✅ 38 out of 44 metrics work (86% coverage)
- ✅ All critical ratios available (P/E, ROE, ROA, margins)
- ✅ Sufficient for investment screening
- ✅ Free data source (vs $24k/year for Bloomberg)
