|----------|--------|--------|-----------|--------|-----------|
| | | | | | |

**Concentration analysis:**

| Metric | Value | Limit | Status |
|--------|-------|-------|--------|
| Top 10 holdings % | XX% | Typically  50% | Review |
| 停牌股票 | Suspended positions | Valuation review |
| 退市风险 | Delisting risk | Consider exit |
| ST持仓 | Distressed securities | Review necessity |
| 流动性不足 | Hard to exit | Assess impact |
