Agent驱动的十大股东追踪系统：用AI挖掘机构持仓变动的领先信号

十大股东数据是追踪机构动向的重要窗口。国家队、社保基金、QFII出现在十大股东里，往往意味着机构看好这只股票。但十大股东数据维度多、更新频率低，人工分析效率低。最近我用AI Agent构建了一个十大股东追踪系统，让Agent自动从股东数据中挖掘机构持仓变动的信号。

系统把十大股东分析拆解成几个子任务：机构身份识别、持仓变动追踪、股东人数分析、持股集中度评估。每个子任务交给专门的模块处理，Agent负责汇总各模块结果生成综合判断。

数据层使用本地数据引擎，主要用到四个接口。十大股东接口time/f10/zygd/{股票代码}，返回截止日期、公告日期、股东总数、平均持股、十大股东列表。十大流通股东接口time/f10/zygdlt/{股票代码}，结构类似但只看流通股东。股东变化趋势接口time/f10/gdbh/{股票代码}，返回各季度的股东户数变化。基金持股接口time/f10/jjcg/{股票代码}，返回基金持仓数据。

```python
class ShareholderAgent:
    def __init__(self, data_engine):
        self.data_engine = data_engine
        self.modules = {
            "institution": InstitutionDetector(),
            "change": HoldingChangeTracker(),
            "count": ShareholderCountAnalyzer(),
            "concentration": ConcentrationEvaluator()
        }
        self.institution_keywords = {
            "national": ["汇金", "证金", "国家队"],
            "social": ["社保"],
            "qfii": ["QFII", "瑞士联合", "摩根", "高盛", "富达"],
            "insurance": ["保险", "人寿", "平安"],
            "fund": ["基金", "资管", "信托"]
        }
    
    def analyze(self, dm):
        zygd = self.data_engine.read_zygd(dm)
        zygdlt = self.data_engine.read_zygdlt(dm)
        gdbh = self.data_engine.read_gdbh(dm)
        jjcg = self.data_engine.read_jjcg(dm)
        
        if not zygd:
            return {"dm": dm, "score": 50, "signal": "无股东数据"}
        
        context = {
            "dm": dm,
            "zygd": zygd,
            "zygdlt": zygdlt,
            "gdbh": gdbh,
            "jjcg": jjcg
        }
        
        results = []
        for module in self.modules.values():
            result = module.analyze(context)
            if result:
                results.append(result)
        
        decision = self.synthesize(results, dm)
        return decision
```

第一个模块是机构身份识别器。它分析十大股东中有没有国家队、社保、QFII等重要机构。

```python
class InstitutionDetector:
    def analyze(self, context):
        zygd = context["zygd"]
        if not zygd:
            return None
        
        latest = zygd[0]
        holders = latest.get("ZygdSdgd", [])
        
        agent = ShareholderAgent.__new__(ShareholderAgent)
        keywords = {
            "national": ["汇金", "证金", "国家队"],
            "social": ["社保"],
            "qfii": ["QFII", "瑞士联合", "摩根", "高盛", "富达"],
            "insurance": ["保险", "人寿", "平安"],
            "fund": ["基金", "资管", "信托"]
        }
        
        institutions_found = {}
        for holder in holders:
            name = holder.get("股东名称", "")
            for inst_type, kws in keywords.items():
                for kw in kws:
                    if kw in name:
                        if inst_type not in institutions_found:
                            institutions_found[inst_type] = []
                        institutions_found[inst_type].append(name)
                        break
        
        signal = {
            "module": "institution",
            "institutions": institutions_found
        }
        
        if "national" in institutions_found:
            signal["signal"] = "国家队进驻，中长期看好"
            signal["score"] = 72
        elif "social" in institutions_found:
            signal["signal"] = "社保基金进驻"
            signal["score"] = 70
        elif "qfii" in institutions_found:
            signal["signal"] = "QFII进驻"
            signal["score"] = 68
        elif "fund" in institutions_found or "insurance" in institutions_found:
            signal["signal"] = "机构资金进驻"
            signal["score"] = 62
        else:
            signal["signal"] = "十大股东以个人或普通企业为主"
            signal["score"] = 48
        
        return signal
```

第二个模块是持仓变动追踪器。它对比相邻季度的十大股东名单，找出新进和退出的股东。

```python
class HoldingChangeTracker:
    def analyze(self, context):
        zygd = context["zygd"]
        if not zygd or len(zygd) < 2:
            return None
        
        latest = zygd[0]
        prev = zygd[1]
        
        latest_holders = set()
        for h in latest.get("ZygdSdgd", []):
            latest_holders.add(h.get("股东名称", ""))
        
        prev_holders = set()
        for h in prev.get("ZygdSdgd", []):
            prev_holders.add(h.get("股东名称", ""))
        
        new_in = latest_holders - prev_holders
        exited = prev_holders - latest_holders
        
        keywords = ["基金", "社保", "保险", "信托", "QFII", "证金", "汇金", "资管"]
        new_institutions = [h for h in new_in if any(kw in h for kw in keywords)]
        exited_institutions = [h for h in exited if any(kw in h for kw in keywords)]
        
        signal = {
            "module": "change",
            "new_holders": list(new_in),
            "exited_holders": list(exited),
            "new_institutions": new_institutions,
            "exited_institutions": exited_institutions
        }
        
        if new_institutions and not exited_institutions:
            signal["signal"] = "机构新进且无机构退出"
            signal["score"] = 72
        elif exited_institutions and not new_institutions:
            signal["signal"] = "机构退出且无机构新进"
            signal["score"] = 38
        elif new_institutions and exited_institutions:
            signal["signal"] = "机构有进有出，筹码换手"
            signal["score"] = 55
        else:
            signal["signal"] = "十大股东变动以个人为主"
            signal["score"] = 50
        
        return signal
```

第三个模块是股东人数分析器。它分析股东户数的变化趋势。

```python
class ShareholderCountAnalyzer:
    def analyze(self, context):
        gdbh = context["gdbh"]
        if not gdbh or len(gdbh) < 2:
            return None
        
        df = pd.DataFrame(gdbh)
        df.columns = ["jzrq", "gdhs", "bsqbh"]
        df["gdhs"] = pd.to_numeric(df["gdhs"], errors="coerce")
        df = df.sort_values("jzrq")
        
        latest = df.iloc[-1]
        prev = df.iloc[-2]
        
        change_pct = (latest["gdhs"] - prev["gdhs"]) / prev["gdhs"]
        
        signal = {
            "module": "count",
            "latest_gdhs": latest["gdhs"],
            "change_pct": change_pct
        }
        
        if change_pct < -0.15:
            signal["signal"] = "股东人数大幅减少，筹码集中"
            signal["score"] = 68
        elif change_pct > 0.15:
            signal["signal"] = "股东人数大幅增加，筹码分散"
            signal["score"] = 38
        else:
            signal["signal"] = "股东人数变化不大"
            signal["score"] = 50
        
        return signal
```

第四个模块是持股集中度评估器。它通过平均持股和十大股东持股比例评估筹码集中度。

```python
class ConcentrationEvaluator:
    def analyze(self, context):
        zygd = context["zygd"]
        if not zygd:
            return None
        
        latest = zygd[0]
        avg_holding = latest.get("平均持股", 0)
        total_count = latest.get("股东总数", 0)
        
        holders = latest.get("ZygdSdgd", [])
        top10_ratio = sum(h.get("持股比例", 0) for h in holders)
        
        signal = {
            "module": "concentration",
            "avg_holding": avg_holding,
            "top10_ratio": top10_ratio
        }
        
        if top10_ratio > 70:
            signal["signal"] = "十大股东持股比例高，筹码高度集中"
            signal["score"] = 65
        elif top10_ratio < 20:
            signal["signal"] = "十大股东持股比例低，筹码分散"
            signal["score"] = 45
        else:
            signal["signal"] = "筹码集中度中等"
            signal["score"] = 50
        
        return signal
```

Agent的决策模块把四个模块的结果汇总。

```python
def synthesize(self, results, dm):
    if not results:
        return {"dm": dm, "score": 50, "signal": "数据不足"}
    
    weights = {"institution": 0.35, "change": 0.3, "count": 0.2, "concentration": 0.15}
    
    total_score = 0
    total_weight = 0
    signals = []
    
    for r in results:
        w = weights.get(r.get("module", ""), 0.1)
        total_score += r.get("score", 50) * w
        total_weight += w
        signals.append(r.get("signal", ""))
    
    final_score = total_score / total_weight if total_weight > 0 else 50
    
    if final_score >= 65:
        action = "股东结构信号偏多，机构看好"
    elif final_score <= 40:
        action = "股东结构信号偏空，机构谨慎"
    else:
        action = "股东结构信号中性"
    
    return {
        "dm": dm,
        "score": round(final_score, 1),
        "action": action,
        "signals": signals
    }
```

几个使用经验。第一，十大股东数据是季度披露的，有滞后性，但机构动作往往领先股价。第二，机构新进比机构增持信号更强，因为新进意味着从无到有。第三，股东人数减少要配合业绩看，业绩增长的筹码集中才有意义。第四，十大股东的季度变动比静态名单更有价值。

系统使用的数据来自ig50本地数据接口，十大股东、十大流通股东、股东变化趋势、基金持股这些接口配合使用，能构建完整的股东结构分析系统。
