## Investment Analysis Workflow

When the user asks about stock performance, portfolio advice, or market analysis:

1. **Get live data** via CLI — quotes, positions, K-line history, intraday
2. **Get news/catalysts** via CLI — **prefer Longbridge first**; fall back to WebSearch only if insufficient
3. **Combine** — price action + volume + catalyst → analysis + suggestion

```bash
# Market data
longbridge quote SYMBOL.US
longbridge positions                # always pull when user asks about "my portfolio"
longbridge kline-history SYMBOL.US --start YYYY-MM-DD --end YYYY-MM-DD --period day
longbridge intraday SYMBOL.US

# News & content (prefer these over WebSearch)
longbridge news SYMBOL.US           # latest news articles
longbridge news-detail <id>         # full article content
longbridge filing-detail <id>       # regulatory filing (earnings reports, etc.)
longbridge topics SYMBOL.US         # community discussion
longbridge market-temp              # market sentiment index (0–100)
```

Only fall back to WebSearch when Longbridge news is insufficient (e.g., breaking news not yet indexed, macro events unrelated to a specific symbol).
