Closing Thoughts
The episodes for Solar and Wind run through Mar 31, so the next session will show whether those moves continue. The Battery episode ends on Mar 30.
News reports linked the battery and plastic moves to rising oil prices and worries about naphtha supply. Whether those pressures last may decide if the gains hold.
