AnnouncementDelta: Institutional-Grade Announcement Filtering & Alert Service

A human-powered announcement triage service that employs financial analysts in tier-2 Chinese cities to read and categorize company announcements (earnings, management changes, regulatory filings, M&A, guidance revisions) within 90 seconds of publication, then instantly push only material, actionable signals to subscribers via WeChat/SMS with pre-written trade thesis summaries. Analysts apply a proprietary rubric: materiality score (1-10), trade direction (long/short/neutral), catalyst window (hours/days), and risk flags (litigation, audit, delisting risk).

SERVICE

26 weeks • 70% confidence

Value Proposition

Beats news aggregators because it filters to <2% of announcements (only material ones), beats financial websites because delivery is 3–5 minutes faster than any portal, and beats AI-only solutions because human analysts catch context and nuance (e.g., 'new CFO from competitor' vs. 'new CFO from accounting firm'). Subscribers make decisions on complete thesis, not raw data.

Target Audience

Day traders and swing traders on Chinese exchanges (A-shares, HK-listed); retail investors with 50K–500K CNY portfolios; small prop trading desks with <10 people

Key Features

  • Real-time announcement ingestion from CNINFO, exchange filings, and company WeChat official accounts
  • Materiality scoring engine trained on historical price moves post-announcement
  • WhatsApp/WeChat instant alerts with 50-word thesis, suggested entry/exit levels, and risk warnings
  • And more, with full implementation detail...

Tech Stack

Web scraper (Python + Selenium for CNINFO, Tencent API for HK exchange) WeChat Official Account API and SMS gateway (Aliyun or Tencent Cloud) Simple web dashboard (React + Node.js backend, PostgreSQL for alert logs and user data) Slack/DingTalk for internal team coordination

Original Problem

Chinese retail investors struggle to quickly identify actionable stock opportunities and company announcements amid information overload

Chinese stock market participants face daily information paralysis trying to filter through thousands of company announcements and market signals to find tradeable opportunities. Current solutions (financial websites, news aggregators) deliver information too slowly or in overwhelming volume, causing investors to miss time-sensitive trading windows or make decisions based on incomplete data. Real-time, curated market intelligence that separates signal from noise is desperately needed.
