longbridge-adr-premium

Cross-market premium / discount analysis for companies dual- or triple-listed as ADR (US), H-share (HK), and/or A-share (CN).

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

When to use

Trigger on prompts asking about:

ADR vs H-share premium / discount — "BABA ADR 溢价", "百度 ADR 和港股哪个便宜"
Three-market comparison — "BABA.US / 9988.HK / 阿里A股比价"
Theoretical arbitrage spread and constraints — "ADR 套利空间", "ADR arbitrage"
Dual-listing pricing discrepancy — "dual-listed premium", "跨市场套利"

For pure A/H premium time series defer to

longbridge-ah-premium

.

Workflow

Identify all available listing venues for the company (ADR ticker, HK code, A-share code).
Fetch real-time quotes for each venue.
Fetch USD/HKD and USD/CNY exchange rates.
Convert all prices to a common currency (USD) using the ADR ratio where applicable.
Calculate premium / discount between each pair:
```
(Price_A − Price_B) / Price_B × 100%
```
.
Assess arbitrage constraints: FX repatriation rules, stamp duty, liquidity depth, settlement lag.
Output a comparison table and narrative.

If unsure of exact flag names, run
longbridge <subcommand> --help
before proceeding.

CLI

bash

# Quotes for each listing venue
longbridge quote <ADR_SYMBOL> --format json
longbridge quote <HK_SYMBOL> --format json
longbridge quote <A_SYMBOL> --format json   # omit if no A-share listing

# Exchange rates for currency conversion
longbridge exchange-rate --format json

Common examples:

Company	ADR	H-share	A-share
Alibaba	BABA.US	9988.HK	—
Baidu	BIDU.US	9888.HK	—
JD.com	JD.US	9618.HK	—
NIO	NIO.US	9866.HK	—

Output

Present a summary table then a narrative:

Symbol        Price (local)   Price (USD)   vs ADR
──────────────────────────────────────────────────
BABA.US        $82.50          $82.50        baseline
9988.HK        HK$638.00       $81.79        −0.9%

Then explain:

Which venue is cheapest / most expensive and why.
Arbitrage constraints (FX controls, transaction costs, liquidity).
Whether the spread is actionable or structural.
