Closing Thoughts
All eight themes were recurrences, and Petrochemicals came back after a 64-day gap. Only Semiconductors has an episode end date of 2021-12-02.
Each theme has a streak of 1, so the next session will show whether any of them extends. Headlines linked Nuclear to next year’s presidential election and Market Kurly to a pre-IPO.
