What to Watch Next Week
Pharma, Wind, Biosimilars and Cold Chain Logistics ended the week on a consecutive run. The first thing to check is whether those streaks continue.
Construction Majors had its best day of 7.26% on May 23, the same day as Nuclear’s 16.59%. Both peaked in the final session, and next week will show whether that carries over.
