longbridge-smallcap-growth

Screens for overlooked small/mid-cap high-growth stocks across US, HK, and A-share markets using quantitative filters (market cap, revenue growth, ROE) and qualitative overlays (sector focus, 专精特新 category for A-shares).

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

When to use

Trigger when the user wants to find small or mid-cap growth names:

• "帮我找一些专精特新的小盘成长股" / "幫我發掘港股中小市值成長股" / "Find me high-growth small caps in the US"
• "隐形冠军", "小盘成长", "small cap discovery", "emerging growth stocks"

Default screening criteria

Ask the user if they want to adjust any threshold before running.

Workflow

1. Clarify market (US / HK / A-share / all) and any sector preference.
2. Fetch index constituents for the relevant small/mid-cap indices (e.g. IWM.US for Russell 2000, 399006.SZ for ChiNext, 399005.SZ for SME Board).
3. For each constituent, fetch market cap via calc-index and filter by size.
4. For size-passing candidates, fetch the latest income statement to check revenue growth.
5. Further filter by ROE from the balance sheet / financial-report data.
6. Return the top 10 candidates ranked by revenue growth rate, with a brief profile for each.
