Portfolio Analysis (from /api/recommendations):

# 今日股票推荐分析报告

## 核心推荐逻辑
本次推荐聚焦**金融板块**优质标的，四只推荐股票均呈现**均线金叉**与**RSI强势**双重技术信号共振，
评分集中在99.86-99.91高分区间，预期收益率统一为7.5%。策略核心是捕捉金融股技术面突破带来的短期上涨动能。

## 市场机会与风险
**主要机会：**
- 金融板块出现明显的技术性买入信号，短期上涨概率较高
- 推荐标的技术指标高度一致，显示板块轮动特征明显

**主要风险：**
- 市场整体情绪中性，大盘缺乏明确方向，存在震荡风险
- 四只股票技术信号完全同质化，缺乏分散性，板块联动风险较高
- 7.5%预期收益设定较为激进，需警惕回调

## 投资建议
1. **仓位控制**：建议单一标的仓位不超过总资金的15%，四只合计不超过40%
2. **分批建仓**：采用2-3日分批买入策略，避免追高风险
3. **设置止损**：建议在买入价下方5%设置止损位，保护本金安全

Individual Stock Analysis (from /api/recommendations/600000):

# 股票600000投资分析报告

**技术面评估：强势**
该股呈现典型多头格局，MA5金叉MA20显示短期动能强劲，RSI超70进入超买区，
配合成交量放大，表明资金积极介入。近5日连续上涨确认上升趋势。

**基本面警示：数据缺失**
PE、PB均为0存在异常，可能是ST股、亏损股或数据未披露。行业信息未知，
无法评估估值合理性和成长性，基本面支撑严重不足。

**投资建议：谨慎持有/减仓**
技术面虽强但RSI超买存在回调风险，基本面数据缺失令投资决策缺乏依据。
建议：已持仓者设好止盈（9.5元附近）；新资金暂时观望，待基本面明朗后再介入。

**风险等级：高**
数据透明度低、超买状态、基本面不明构成三重风险，不适合稳健型投资者。

2. 📊 Data Source - CONFIRMED USING MOCK DATA (with Fallback Chain)

Current Data Source Flow:

Request for Stock Data
    ↓
[STEP 1] TuShare API
├─ Status: ❌ FAILED (Invalid token: "您的token不对，请确认")
├─ Reason: Provided token is invalid or expired
└─ Fallback: Continue to next source
    ↓
[STEP 2] yfinance API
├─ Status: ❌ FAILED (No price data for Chinese A-stocks)
├─ Reason: yfinance doesn't support Chinese A-stock symbols (600000.SS format)
├─ Error: "No price data found, symbol may be delisted"
└─ Fallback: Continue to next source
    ↓
[STEP 3] Mock Data Generation
├─ Status: ✅ ACTIVE (Currently in use)
├─ Method: Generate random OHLCV data with technical indicators
└─ Result: System fully operational with demonstrative data

Backend Logs - Evidence of Fallback Chain:

📥 Fetching data for 600000...
🔄 Fetching from TuShare: 600000.SH (20250812 to 20251110)...
⚠️  TuShare fetch failed for 600000: 您的token不对，请确认。
⚠️  No data available for 600000
⚠️  Using mock data for 600000...

📥 Fetching data for 600031...
🔄 Fetching from TuShare: 600031.SH (20250812 to 20251110)...
⚠️  TuShare fetch failed for 600031: 您的token不对，请确认。
⚠️  No data available for 600031

⚠️  Using mock data for demonstration...

Data Source Configuration (backend/app/modules/data_fetcher.py:50-77):

# Try TuShare first for Chinese A-stocks
if self.tushare_token and (symbol.startswith("6") or symbol.startswith("0") or symbol.startswith("3")):
    df = self._fetch_tushare_data(symbol, period)
    if df is not None and not df.empty:
        data[symbol] = df
        print(f"✅ Fetched {len(df)} records for {symbol} from TuShare")
        continue

# Fallback to yfinance
symbol_converted = self._convert_symbol(symbol)
df = yf.download(
    symbol_converted,
    period=period,
    interval=interval,
    progress=False
)

if df is not None and not df.empty:
    data[symbol] = df
    print(f"✅ Fetched {len(df)} records for {symbol} from yfinance")
else:
    print(f"⚠️  No data available for {symbol}")

Mock Data Characteristics:

Aspect	Details
Structure	Realistic OHLCV (Open, High, Low, Close, Volume)
Date Range	Last 60 days of historical data
Price Range	8-12 CNY range (realistic for mid-cap stocks)
Volume	1M-5M shares (realistic trading volume)
Indicators	30+ technical indicators computed in real-time
ML Scoring	XGBoost model trained on 1000 samples
Claude Analysis	Real-time analysis of mock data

Sample Current API Response:

4. ⚠️ Current Limitations & How to Get Real Data

Why Mock Data is Currently Active:

1. TuShare Token Issue

   • Current token: 0210e126e9da79b6e0d30d6a663fc605577c5754281cd3a9a74d3bad
   • Status: ❌ Invalid or expired (error: "您的token不对，请确认")
   • Solution: Get new token from https://tushare.pro/

2. yfinance Limitation

   • Cannot fetch Chinese A-stock data (600000.SS format)
   • This is a yfinance library limitation, not a system bug

How to Enable Real Data:

Option 1: Update TuShare Token (Recommended)

# 1. Visit https://tushare.pro/ and register
# 2. Get your API token
# 3. Update .env file:
echo "TUSHARE_TOKEN=your_new_valid_token" >> .env

# 4. Restart backend:
docker compose restart backend

# 5. Clear cache (optional):
docker compose exec redis redis-cli FLUSHALL

# 6. Test:
curl http://85.239.237.116:8001/api/recommendations | python3 -m json.tool

Option 2: Implement Alternative Data Source

• Edit backend/app/modules/data_fetcher.py
• Add new method _fetch_bloomberg_data() or similar
• Update priority chain in fetch_stock_data()

7. 🚀 Next Steps

To Get Real Data:

1. Register at https://tushare.pro/ for a valid token
2. Update .env and restart backend
3. System will automatically prioritize TuShare over mock data
