# Stock Market Pro

Comprehensive US and China A-share market analysis. Supports institutional holdings tracking, smart money flows, quotes, and visualization.

## When to Use

- User asks about US stock institutional holdings (13F, holding reports)
- User wants to track Smart Money flows
- User needs stock quotes, candlestick charts, technical indicators
- User requests financial analysis, valuation comparison
- User follows Chinese ADRs, ETF fund flows

## Core Capabilities

### 1. US Stock Institutional Holdings Analysis

Use Python + yfinance/finnhub (free data sources):

```python
# Install dependencies
# pip install yfinance pandas

import yfinance as yf
import pandas as pd

# Get stock institutional holdings
ticker = yf.Ticker("AAPL")
institutional_holders = ticker.institutional_holders
major_holders = ticker.major_holders
mutualfund_holders = ticker.mutualfund_holders
```

### 2. Stock Quotes & Fundamentals

```python
# Real-time/historical quotes
ticker = yf.Ticker("NVDA")
hist = ticker.history(period="1mo")  # 1d, 5d, 1mo, 3mo, 6mo, 1y, max
info = ticker.info  # Company fundamentals
financials = ticker.financials  # Financial statements
balance_sheet = ticker.balance_sheet  # Balance sheet
recommendations = ticker.recommendations  # Analyst ratings
```

### 3. Smart Money Flow Tracking

- ARK Invest daily trade disclosures
- 13F quarterly holdings changes (WhaleWisdom, SEC EDGAR)
- Unusual options activity
- Insider trading

### 4. China A-Share Data

This skill focuses on US stocks. For A-share data, use specialized China market data sources (Tushare, AKShare, etc.).

## Data Source Priority

1. **yfinance** — Free quotes and fundamentals (preferred)
2. **Finnhub** — Free API (API key required, optional)
3. **SEC EDGAR** — 13F raw holdings data
4. **Web Search** — Real-time news and updates

## Output Standards

- **Color convention**: Up/Rise → Red (red), Down/Fall → Green (green) — follows Chinese market convention
- Currency: $ for US stocks, ¥ for A-shares
- Institutional holdings changes displayed in tables
- Price trends displayed with charts/visualizations

## Typical Workflow

1. User asks about a stock → yfinance fetch quotes + fundamentals
2. User asks about institutional holdings → Fetch institutional_holders + 13F changes
3. User asks about smart money → Search latest ARK/13F/insider updates
4. Generate analysis report or visualization
