longbridge-corporate-events

Event-driven analysis for a single listed company: identifies, classifies, and scores corporate events that may create short- to medium-term pricing dislocations.

Response language: match the user's input language —

Simplified Chinese / Traditional Chinese / English.

When to use

• "AAPL 最近有什么大事件", "700.HK corporate events" → full event scan
• "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 / longbridge-earnings), real-time quotes (→ longbridge-quote), or deep broker-level ownership (→ longbridge-flows).

Workflow

1. Resolve the user's symbol to <CODE>.<MARKET> (e.g. AAPL.US, 700.HK, 600519.SH).
2. Run longbridge --help to see available subcommands; run longbridge <subcommand> --help to confirm current flags for each.
3. Fetch latest news and announcements using the news subcommand with --format json.
4. Fetch regulatory filings using the filings subcommand with --format json.
5. Fetch corporate actions (dividends, splits, rights, buyback notices) using the corporate-actions subcommand with --format json.
6. Fetch major shareholder changes using the shareholder subcommand with --format json.
7. Optionally fetch earnings / event calendar using the finance-calendar subcommand with --format json to surface upcoming catalysts.
8. Classify each event into one of the standard types (see Output), assess sentiment (+/−/neutral), and estimate the expected price-impact window.
9. Output the event ledger and a summary directional signal.

Output

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

1. Event ledger — chronological list: date / type / headline / sentiment (+/−/neutral) / expected impact window.
2. Top signal — the single most market-moving event from the list, with a one-sentence rationale.
3. Directional bias — net assessment (accumulation / distribution / neutral), based on the balance of bullish vs bearish events in the last 30 days.
4. 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.
