What to Watch Next Week
Every theme this week carried a recurrence tag, so none is new to the board. The open question is whether North Korea, strong on 2 days, holds momentum past its Sep 18 peak.
Single-day themes include Construction at 6.41%, Media (Broadcast & Press) at 4.7%, 5G / Telecom Equipment at 2.69% and Car Majors at 1.48%. Whether any extend past one day is the next test.
