Rio Tinto (RIO): news on Saturday 31 October 2026
News from the 24 hours to Saturday morning, 31 October 2026.
Tone of the day
What the score means. Each score rates how good or bad the news was for the company, from −10 (clearly bad) to +10 (clearly good). 0 is neutral, and anything beyond ±6 is strong and rare. It rates the coverage, not the share price.
Why it scored this way
Coverage was dominated by the seismic event at Oyu Tolgoi, with the halt and confused updates weighing before the restart began. Falling earnings per share and share price weakness added pressure, partly offset by the new Argentine lithium operations.
What drove it
- Oyu Tolgoi disruption and restart
- lower earnings and share price
- Argentine lithium launch
