What's next — scenarios
Sector Rotation Continuation (Base Case) (50%)
Retail capital will continue rotating from defensive sectors into high-growth momentum stocks, increasing volatility in mid-cap equities.
- Sustained net inflows into high-growth sectors
- Stable retail trading volumes via Flatex
Retail Momentum Peak (Upside/Correction Risk) (30%)
The 58% gain represents a local top, leading to a profit-taking wave that drains liquidity from high-performing German equities.
- Significant sell-side volume in the most popular stock
- Decrease in domestic net inflows for the winning sector
Risk-Averse Flight (Downside) (20%)
Retail investors revert to defensive sectors, causing a liquidity crunch in the high-growth stocks that drove May's performance.
- Net outflows from the top-performing sector
- Increase in domestic outflows across all equity sectors
