Stock	Streak	Streak Return
C Cenergy Holdings \| CENER Industrials \| Large Cap	2 weeks ↑	14.45%
V Viohalco S.A \| VIO Industrials \| Large Cap	2 weeks ↑	9.23%
S Syneos Health \| SYENS Basic Materials \| Large Cap	4 weeks ↓	-12.63%
Syneos Health pulls back after a 4-week decline (78.22 → 68.34), down 12.6%. Weak margins on 1.7B revenue with only 2.0M profit (0.1% margin) in Qtr ending Mar 2025 validate market skepticism. Structural improvements needed before sentiment shifts.
S Solvay SA \| SOLB Basic Materials \| Large Cap	4 weeks ↓	-8.82%
Solvay SA takes a breather following a 4-week decline (29.04 → 26.48), down 8.8%. Revenue of 1.2B provides a foundation, but 83.0M net income (6.7% margin) in Qtr ending Mar 2025 highlights operational challenges that need addressing.
E Exmar N.V \| EXM Energy \| Mid Cap	4 weeks ↑	23.76%
A Ascencio SCA \| ASCE Real Estate \| Mid Cap	3 weeks ↑	4.38%
K Kinepolis Group NV \| KIN Communication Services \| Mid Cap	5 weeks ↓	-12.14%
E Econocom Group S.E \| ECONB Technology \| Mid Cap	5 weeks ↓	-5.49%
C CMB Tech N.V \| CMBT Energy \| Small Cap	1 weeks ↓	-5.35%
CMB Tech N.V takes a breather following a 1-week decline (9.72 → 9.20), down 5.3%. However, fundamentals remain robust: 235.0M revenue generating 40.4M profit (17.2% margin) as of Qtr ending Mar 2025 suggests this could be a temporary setback. Value hunters take note.
