Closing Thoughts
Novatech, up 21.71%, led both Smartphones and Rare Earths & Rare Metals, as news cited hopes tied to China’s rare earth export halt. Whether that link holds is a key thread.
Medical AI, led by Tomatosystem at 24.83%, and AI Chatbots have both run 4 days since Apr 11. Whether those streaks extend is the next test.
