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

CLI

# 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.
