About this app

A sharp rise or fall in one company's stock price can have ripple effects on its trading partners.

When a listed company's stock price moves significantly, the impact of its earnings reports and news can spread to other listed companies (trading partners and suppliers) connected through business transactions. "Stock Price Spillover Alert" is a Japanese stock app that quickly notifies you via push notifications of the potential for ripple effects on related stocks connected through the supply chain. It visualizes the often overlooked connections of "association and ripple effects."

■ Recommended for these investors:
・Those who track news stocks, related stocks, theme stocks, and related stocks in the Japanese stock market.
・Those who diligently check earnings reports, timely disclosures, and IR.
・Those looking for "the next stock to move" in day trading/swing trading.
・Those who want to anticipate and target small and mid-cap stocks that are affected by sudden changes in large-cap stocks.

■ Main Features
・Automatically detects stocks that have surged or fallen and automatically generates alerts to companies connected through business relationships.
・Displays "Sales Dependency" and "Purchase Dependency" for each alert. The higher the dependency, the greater the impact on the stock price.
- Display the strength of the impact as a score from 0 to 100 (strong correlation = red / medium correlation = orange / reference = blue), allowing you to see the level of attention at a glance.
- Quickly switch between "Today / Yesterday / Previously" segments.
- Filter by impact score to display only high-priority alerts.
- Automatically adapts to your device's light/dark theme.

■ Basis for Impact
Inter-company transaction relationships (customers and suppliers) are organized based on publicly available information such as securities reports. We reverse-lookup "which company depends on which customer and to what extent for sales and purchases," and display the potential for impact as a score. This visualizes how positive or negative news from one company could have an impact on other stocks—the connections are clearly shown.

■ How to Use
1. Turn on notifications.
2. When a stock experiences significant price fluctuations, you will receive push notifications about related stocks that may be affected.
3. Quickly identify noteworthy related stocks by looking at sales dependency, procurement dependency, and ripple effect scores.
