Here are the companies making notable moves in midday trading:

Freeport-McMoRan — Shares of the mining giant climbed 3.1%, lifted by a sustained rally in precious metals. Gold and other metals have scaled to record highs this week, boosting sentiment across the commodities sector.

Target — The retailer advanced more than 1% following a Financial Times report that hedge fund Toms Capital Investment Management has taken a significant activist stake in the company. The move adds pressure on Target, which is down more than 27% year-to-date, as investors watch for potential strategic shifts.

Coupang — The South Korean e-commerce firm rallied 8% after announcing that the perpetrator of a recent cybersecurity incident had been identified. The company assured that leaked data was limited to about 3,000 accounts, easing broader data breach concerns that had weighed on the stock.

Nvidia — The semiconductor leader added 1% after confirming its $20 billion acquisition of assets from AI startup Groq—its largest purchase ever. The deal reinforces Nvidia’s push to consolidate its position in the competitive artificial intelligence infrastructure market.

Airline Stocks — Carrier shares declined as a winter storm disrupted flight schedules during the busy holiday period. United Airlines fell 0.7%, American Airlines dropped 1.9%, and Delta Air Lines lost 0.6%, reflecting near-term operational and revenue risks from weather-related travel disruptions.
