Sibanye Gold is trading 4.25% higher at $9.82 in pre-market on October 15, after closing at $9.42 on October 14; no clear company-specific catalyst was identified. - A disclosure said UBS Group AG’s aggregate interest reached 5.02%, but did not establish that it caused the gain. - Hotter-than-forecast U.S. CPI revived rate concerns, while reports described pressure on platinum-group metal prices; this backdrop does not clearly explain the pre-market rise.
