longbridge-constituent

List the constituent stocks of an index or ETF, ranked by a chosen indicator.

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

When to use

Trigger when the user wants the members of an index or ETF (not the index quote itself):

• "标普 500 有哪些股票", "S&P 500 constituents" → SPX.US
• "恒生指数成分股", "Hang Seng constituents" → HSI.HK
• "纳斯达克 100 涨幅榜", "IXIC components by gain" → IXIC.US
• "沪深 300 成分股", "CSI 300 members" → 000300.SH
• "QQQ 持仓", "SPY holdings" → ETF symbol like QQQ.US, SPY.US

For the index quote (level, change, volume), use longbridge-quote instead. For 2–5 explicit-symbol comparison, use longbridge-peer-comparison.

Symbol format

<CODE>.<MARKET>. Common indices:

Index	Symbol
恒生指数 / Hang Seng	HSI.HK
国企指数 / HSCEI	HSCEI.HK
标普 500 / S&P 500	SPX.US
道琼斯 / Dow Jones	DJI.US
纳斯达克综合 / Nasdaq	IXIC.US
纳指 100 / Nasdaq 100	NDX.US
沪深 300 / CSI 300	000300.SH
上证指数 / SSE Composite	000001.SH

ETFs use their own ticker (e.g. SPY.US, QQQ.US, 2800.HK).

Subcommand

Single CLI command. Run longbridge constituent --help if unsure of current flags.

longbridge constituent <SYMBOL> [--limit N] [--sort INDICATOR] [--order desc|asc] --format json

Flag	Default	Notes
--limit	50	Number of members to return
--sort	change	change / price / turnover / inflow / turnover-rate / market-cap
--order	desc	desc / asc

Workflow

1. Resolve the user's index/ETF name to <CODE>.<MARKET> (use the table above; if ambiguous between markets, ask).
2. Pick --sort from intent:
   • "涨幅榜 / gainers" → --sort change --order desc
   • "跌幅榜 / losers" → --sort change --order asc
   • "成交活跃 / most traded" → --sort turnover
   • "主力净流入 / net inflow" → --sort inflow
   • "权重股 / largest weight" → --sort market-cap
3. Pick --limit: default 50 unless user specifies (e.g. "前 10" → --limit 10).
4. Run longbridge constituent ... --format json, render the rows in a table.

CLI examples

longbridge constituent HSI.HK                                     --format json
longbridge constituent HSI.HK --limit 20 --sort change            --format json
longbridge constituent SPX.US --sort market-cap --limit 10        --format json
longbridge constituent IXIC.US --sort inflow --order desc         --format json
longbridge constituent 000300.SH --sort turnover --limit 30       --format json
longbridge constituent QQQ.US                                     --format json

Output

JSON array, one row per constituent — fields typically include symbol, name, last, change_rate, volume, turnover, market_cap, plus the indicator used for sorting. Render as a 5–8 column table; preserve symbol verbatim.

Error handling

Situation	LLM response
Shell command not found: longbridge	Fall back to MCP if configured; otherwise tell the user to install longbridge-terminal.
stderr param_error / "invalid symbol"	Confirm the index symbol — e.g. SPX.US not S&P500.
Empty array	"No constituents returned — confirm the symbol is an index or ETF, not a single stock."
Other stderr	Surface verbatim.

MCP fallback

CLI subcommand	MCP tool
constituent <SYMBOL>	mcp__longbridge__index_constituents (or fall back via the equivalent MCP tool)

If unsure of the exact MCP tool name, run the CLI; the binary is the canonical path.
