London, June 6, 2026, 15:02 BST
Glencore shares slipped Friday, though the stock finished the week up. Investors are looking at a sharp slide late in the week after recent gains for the London-listed miner and trader.
The stock closed at 589.20 pence on the LSE, off 20.80 pence, or about 3.4%, from the last session, according to company price data. Shares are still about 3.8% higher than their May 29 finish at 567.80 pence, based on historical market data.
The timing is key since London trading is closed for the weekend. The London Stock Exchange holds regular hours from 8:00 a.m. to 4:30 p.m. local time, Monday through Friday. That means Glencore’s next test will be when cash equity trading starts up again on Monday.
UK stocks had a mixed session. The FTSE 100, which tracks the largest listed companies in London, closed up 0.07% on Friday. But Reuters said both the FTSE 100 and the FTSE 250 mid-cap index declined for the week, with market caution still a factor.
Miners dropped behind the index. Rio Tinto gave up 3.10% Friday and Anglo American was down 5.16%, so Glencore’s loss tracked with broader selling in big diversified mining stocks, not just a single name.
Cerrejón, Glencore’s coal mine in Colombia, halted mining, rail and port activities this week as blockades that started May 23 hit supplies, according to Mining Weekly. The company said any step toward restarting depends on having no more interruptions. Cerrejón declared force majeure during the disruption.
That hits a touchy spot for Glencore. The group held onto coal after previously talking about a spinoff and at the same time has pushed further into copper, which is needed in power grids, EVs and data centers.
Glencore’s Q1 update showed own-sourced copper output up 19% year over year at 199,600 metric tons, with the increase driven by better copper grades in Africa and more throughput at Antamina in Peru. The company maintained its 2026 production forecast and said its marketing unit should beat the full-year profit target range, according to Reuters.
Glencore CEO Gary Nagle said in the April production update that first-quarter output was “largely in line with our expectations.” Nagle added that full-year guidance was unchanged. That’s enough for bulls: Friday’s fall didn’t alter the operating targets. Glencore
But the risk isn’t small. If problems in Colombia keep going, if coal prices keep falling, or if copper loses ground, investors could see Friday’s drop as more than just profit-taking. Colombia’s government has already called on Glencore to talk with local officials and communities about closing Cerrejón. Mines and Energy Minister Edwin Palma said those talks shouldn’t wait for the concession’s last years.
For the coming week, it’s more about seeing confirmation than focusing on where the price closes. Investors want to see if Glencore can hang on to last week’s gains, if Rio Tinto and Anglo American steady, and if Cerrejón releasing any new updates shifts how the market is looking at operational risk.
Glencore heads into the weekend with a weekly gain and steady copper prices, holding guidance unchanged. But shares sold off on Friday as a coal-mine issue unfolded, keeping traders on alert despite the positive move earlier in the week.
