C CMB Tech N.V \| CMBT Energy \| Small Cap	2 months ↑	50.20%
CMB Tech N.V starts to shine with a 2-month winning streak (9.86 → 14.81), delivering 50.2% gains. The financials tell a compelling story: 235.0M revenue generating 40.4M net profit (17.2% margin) demonstrates exceptional profit margins as of Qtr ending Mar 2025.
