Closing Thoughts

Power Equipment and Electric Cables are the only themes on a 3-day streak, so the next sessions will show whether that run continues. News on May 4 linked the move to AI.

The other six themes, including Optical Communications at 13.47%, each had a streak of 1. Whether they show up again is the open question for the coming sessions.
