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

When to use

• "当前哪些行业最强", "which sectors are leading?", "目前哪些行業最強"

For single-stock capital flow route to longbridge-capital-flow. For single-stock valuation route to longbridge-valuation.

Workflow

1. Clarify scope — ask the user for market (A-share / HK / US) and time window (20-day / 60-day) if not given. Default: A-share, 20-day momentum.
2. Select representative sector indices or ETFs for the market:
3. A-share: 申万一级行业指数 (SW L1); common symbols like 801010.SH (agriculture), 801020.SH (mining), 801030.SH (chemicals), 801040.SH (steel), 801050.SH (non-ferrous), 801080.SH (electronics), 801130.SH (media), 801140.SH (retail), 801150.SH (F&B), 801160.SH (home appliances), 801170.SH (auto), 801180.SH (property), 801200.SH (retail), 801710.SH (building materials), 801720.SH (construction), 801730.SH (utilities), 801740.SH (defense), 801750.SH (IT), 801760.SH (telecom), 801770.SH (biotech), 801780.SH (financials), 801790.SH (brokers).
4. HK: use sector ETFs or HSI sub-indices.
5. US: use SPDR sector ETFs (XLK.US, XLF.US, XLE.US, XLV.US, XLY.US, XLI.US, XLP.US, XLB.US, XLRE.US, XLU.US, XLC.US).
6. Fetch kline data for each sector symbol to compute momentum. Run longbridge kline --help to verify exact flags, then call:

``bash longbridge kline <SYMBOL> --format json # run --help for available period/count flags ``

1. Compute momentum score for each sector (LLM in-context):
2. 20-day return: (close[-1] / close[-20]) - 1
3. 60-day return: (close[-1] / close[-60]) - 1
4. Fetch capital flow for top candidates (up to 5 by momentum). Run longbridge capital --help to verify flags, then call:

``bash longbridge capital <SYMBOL> --format json # run --help for time-series vs snapshot flags ``

1. Fetch industry valuation for context:

``bash longbridge industry-valuation <SYMBOL> --format json ` Run longbridge industry-valuation --help` if unsure of flags.

1. Score and rank: combine momentum (60%), capital flow direction (25%), valuation discount vs history (15%). Sort descending.
2. Output the rotation table (see Output section). Cite Longbridge Securities.

CLI

Run --help before calling any subcommand if unsure of flags.

# Step 1: kline for momentum (repeat per sector symbol); run --help for period/count flags
longbridge kline 801750.SH --format json

# Step 2: capital flow for shortlisted sectors; run --help for time-series vs snapshot flags
longbridge capital 801750.SH --format json

# Step 3: industry valuation for context
longbridge industry-valuation 801750.SH --format json

# Sector ETFs for US market
longbridge kline XLK.US --format json
longbridge capital XLK.US --format json

Output

Render as a ranked table, then a short narrative:

Sector Rotation Snapshot — Source: Longbridge Securities
Market: A-share  |  Time: YYYY-MM-DD  |  Momentum window: 20d / 60d

Rank | Sector       | 20d Ret | 60d Ret | Capital Flow | Valuation | Signal
-----|-------------|---------|---------|-------------|-----------|-------
  1  | IT / 信息技术 | +8.2%  | +15.4%  | Net inflow  | Neutral   | ▲ Leader
  2  | Healthcare / 医疗卫生 | +5.1% | +11.2% | Net inflow | Low | ▲ Leader
 ...
 10  | Property / 房地产 | -3.4% | -8.0% | Net outflow | High | ▼ Laggard

Narrative: IT and Healthcare are in the leading quadrant with positive momentum and 
capital inflows. Property and Utilities are lagging. Rotation signal suggests early-cycle 
tilt toward growth sectors.

MCP fallback

When the CLI is unavailable, fall back to the MCP server. Discover available tools from the MCP server's tool list at runtime — do not rely on hardcoded tool names.
