Gold Fields ($GFI) Drops -20.7% Over 30 Days After Northern Star Takeover Bid Rejection (See the latest news for any ticker on Tickeron.) Gold Fields (GFI) shares fell about 20.7% over the 30 days through early October 2026, sliding from $44.92 to $35.62. The steepest single-session move came on September 28, when the stock dropped roughly 12.9% after Northern Star Resources rejected Gold Fields' non-binding takeover proposal. Over the trailing quarter, GFI was essentially flat — a sharp August rally to about $48.87 was fully retraced. Company-specific uncertainty at the Windfall project in Quebec and the Tarkwa lease renewal in Ghana compounded selling pressure. $AU $NEM $KGC $DRD $AEM
