Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be seasonal patterns at play. Has Trade Republic historically experienced similar volume fluctuations during this time of year?

Why it matters: Seasonal trends could explain the decrease and inform our approach to addressing it. Expected answer: No significant seasonal patterns in previous years. Impact on approach: If seasonal, we'd focus on strategies to mitigate annual dips; if not, we'd investigate other factors more deeply.

• Considering recent market conditions, I'm curious about the overall market performance. How has the broader market (e.g., DAX or EURO STOXX 50) performed during this same period?

Why it matters: Market-wide trends could be influencing individual trading behavior. Expected answer: The market has been relatively stable. Impact on approach: If the market is stable, we'd focus more on platform-specific issues; if volatile, we'd consider how to support users during market uncertainty.

• Thinking about user segments, I'm wondering if this decrease is uniform across all user types. Have we seen any differences in trading volume changes between new users and long-term users?

Why it matters: Different user segments may be reacting differently, requiring targeted solutions. Expected answer: The decrease is more pronounced among newer users. Impact on approach: If newer users are more affected, we'd focus on onboarding and early engagement; if uniform, we'd look at platform-wide issues.

• Considering recent platform changes, have there been any significant updates to the app or trading features in the past 1-2 months?

Why it matters: Recent changes could have unintended consequences on user behavior. Expected answer: A new UI for the trading screen was implemented 6 weeks ago. Impact on approach: If recent changes coincide with the decrease, we'd scrutinize those updates; if not, we'd look at other factors.
