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.

CLI

# Discover available subcommands and their flags
longbridge --help
longbridge <subcommand> --help   # run for each subcommand before use

# Latest news and announcements
longbridge <news-subcommand> AAPL.US --format json

# Regulatory filings (SEC 8-K, HKEx announcements, CSRC disclosures)
longbridge <filing-subcommand> AAPL.US --format json

# Corporate actions (dividends, splits, rights, buybacks)
longbridge <corp-action-subcommand> AAPL.US --format json

# Major shareholder changes
longbridge <shareholder-subcommand> AAPL.US --format json

# Upcoming earnings / event calendar
longbridge <finance-calendar-subcommand> --format json

Output

Event classification table

Classify each event found into one of these types:

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.

Error handling

MCP fallback

When the CLI is unavailable, fall back to the MCP server. Discover available tools from the MCP server's tool list at runtime — do not rely on hardcoded tool names.
