# longbridge-sector-screener

Sector screening and ranking — filter and rank industry sectors across A-share / HK / US markets by valuation (PE/PB), capital inflow, price performance (1d/5d/20d), and turnover rate. Outputs a ranked sector leaderboard.

> **Response language**: match the user's input language — Simplified Chinese / Traditional Chinese / English.

## When to use

Trigger when the user asks about:

- Top or bottom performing sectors — *"今天哪个行业涨得最多"*, *"最强势板块"*, *"best performing sectors today"*
- Sector capital flow ranking — *"哪些板块在吸资金"*, *"sectors with net capital inflow"*
- Sector valuation screening — *"哪些行业PE最低"*, *"low-PE sectors"*
- Broad sector overview — *"美股各行业今天表现"*, *"A股行业板块排名"*

For individual stock anomalies, prefer `longbridge-anomaly`. For a single stock's capital flow, prefer `longbridge-capital-flow`. For index constituents, prefer `longbridge-constituent`.

## Workflow

1. Identify the target market (A-share / HK / US) from the prompt.
2. Select representative sector ETFs or indices for that market:
   - **A-share**: major CSI sector indices (e.g. CSI Banks, CSI Tech, CSI Consumer)
   - **HK**: Hang Seng sector sub-indices or sector ETFs
   - **US**: SPDR sector ETFs (XLK, XLF, XLE, XLV, XLI, XLY, XLP, XLU, XLRE, XLB, XLC)
3. Run `longbridge quote` on each sector proxy to get 1d / 5d / 20d performance and turnover rate.
4. Run `longbridge capital` on each sector proxy for net capital inflow.
5. Run `longbridge calc-index` for PE and PB of each sector proxy.
6. Sort and rank by the user's requested criterion; present as a leaderboard table.

## CLI

```bash
# Sector proxy quote (price change, turnover rate)
longbridge quote <SECTOR_SYMBOL> --format json

# Sector capital flow
longbridge capital <SECTOR_SYMBOL> --format json

# Sector valuation
longbridge calc-index <SECTOR_SYMBOL> --index pe_ttm,pb --format json

# Constituent list of a sector index (if drilling into members)
longbridge constituent <INDEX> --format json
```

> Run `longbridge quote --help`, `longbridge capital --help`, and `longbridge calc-index --help` to verify flags.

## Output

A ranked leaderboard table:

| Rank | Sector | 简体 | 繁體 | English |
|---|---|---|---|---|
| 1d change | 今日涨跌幅 | 今日漲跌幅 | 1d change |
| 5d change | 近5日涨跌幅 | 近5日漲跌幅 | 5d change |
| Net capital inflow | 净流入 | 淨流入 | Net inflow |
| PE | 市盈率 | 市盈率 | PE |
| PB | 市净率 | 市淨率 | PB |
| Turnover rate | 换手率 | 換手率 | Turnover rate |

Note: Sector coverage depends on available representative ETFs/indices in Longbridge. Full market-wide sector screening (like Wind or 同花顺) is not supported — the LLM must manually iterate over a curated set of sector proxies.
