The Glencore stock price jumped roughly 15% to 139.70 pence today (Friday) after the company drastically slashed its zinc production.
Zinc prices have fallen 30% in the last few months, prompting the production cut. Today's announcement sent zinc prices soaring more than 11% intraday to $1,850 per metric ton. That was the sharpest gain since at least 1989, according to Bloomberg.
