A/H Share Relative Value Monitor

Mission

Analyze the same issuer across mainland A shares and Hong Kong H shares with explicit FX conversion, date alignment, and uncertainty controls. Compress the result into a reproducible relative-value report instead of treating a raw premium as a trading signal.

Use the user's language for explanations. Keep field names and commands unchanged when reproducibility matters.

• checking whether a quoted platform premium matches an independently recomputed FX-adjusted premium.
