longbridge-corporate-events

"大股东最近增持了吗", "insider buying signal" → shareholder change focus
"NVDA 回购进展", "share buyback update" → news + corp-action focus
"A 股并购重组信号", "M&A catalyst" → news + filing focus
"指数调整对 XX 的影响", "index rebalancing effect" → calendar + news focus

Do not use for financial KPIs / earnings (→

longbridge-fundamental

/

Event classification table

Classify each event found into one of these types:

Type	简体	繁體	English	Typical signal
`increase`	大股东增持	大股東增持	Insider / major-shareholder buy	Bullish
`decrease`	大股东减持	大股東減持	Insider / major-shareholder sell	Bearish
`buyback`	股份回购	股份回購	Share buyback	Bullish
`placement`	定增 / 配股	定增 / 配股	Private placement / rights issue	Dilutive / context-dependent
`incentive`	股权激励	股權激勵	Equity incentive plan	Moderately bullish
`ma`	并购重组	併購重組	M&A / restructuring	Event-specific
`index`	指数调整	指數調整	Index inclusion / exclusion	Inclusion bullish; exclusion bearish
`mgmt`	管理层变更	管理層變更	Management change	Context-dependent
`pledge`	股权质押	股權質押	Share pledge (high ratio)	Bearish risk flag
`st`	ST / 摘帽	ST / 摘帽	A-share ST status change	ST bearish; removal bullish
`other`	其他公告	其他公告	Other filing	Neutral until assessed

Output structure

Event ledger — chronological list: date / type / headline / sentiment (+/−/neutral) / expected impact window.
Top signal — the single most market-moving event from the list, with a one-sentence rationale.
Directional bias — net assessment (accumulation / distribution / neutral), based on the balance of bullish vs bearish events in the last 30 days.
Watch window — suggest the next 1–4 weeks if a pending event (placement lock-up expiry, buyback completion deadline, index review date) is identified.

When no significant events are found, state so explicitly — do not invent signals.

A-share-specific notes:

ST / 摘帽 events have mandatory trading limits and announcement timing rules; flag these clearly.
Northbound (沪深港通) quota changes and index-rebalancing announcements (CSI 300 / SSE 50) are high-impact for A-share mid/large caps.

HK-specific notes:

General mandate issuances (general mandate for new shares) are common HK dilution signals.
Connected-transaction / related-party announcements require regulatory approval and carry governance risk.
