**Why Employee Data Matters**

The Japan Employee Sentiment Signal (JESS) transforms employee reviews, workplace metrics, and organizational health indicators into a predictive stock selection signal for Japanese equities, giving you an early, alternative view of company fundamentals and future performance.

Employees often observe changes in corporate culture, management effectiveness, workforce engagement, and business conditions long before those developments appear in earnings reports or investor communications.

The signal was built on data from OpenWork, Japan's leading employee review platform with 6.9M+ registered users.

**Why It Works**

• **Measures Organizational Health:** Captures employee sentiment, workplace culture, compensation, career development, work-life balance, and management effectiveness

• **Converts Workforce Intelligence into Alpha:** Combines structured employee data with transformer-based analysis of Japanese-language review text

• **Designed for Real-World Implementation:** Built on slow-moving organizational characteristics, resulting in durable signal behavior and low turnover
