Closing Thoughts
Power Equipment was the only theme on a streak, now at 2 days, with Aroot up 30.0%. The other seven came back after gaps of 2 to 4 days.
Each of those seven is on a 1-day episode, so the next sessions will show whether Battery continues. Samsung SDI and LG Energy Solution appear in both battery themes.
