The most significant factor contributing to the decline in Newmont's stock price was the sharp drop in gold prices. Gold fell by more than 4% from its record highs, which led to a significant sell-off in gold-related stocks, including Newmont. This decline in gold prices can be attributed to profit-taking by traders, who booked their profits as the year-end surge in gold prices ended.

Another factor that contributed to the decline in Newmont's stock price was the increase in margin requirements by the CME. The CME raised the cash collateral needed to hold futures, which was effective after the close on Monday, December 29, 2025. This increase in margin requirements can lead to a reduction in leverage and can force traders to cut their exposure, which can lead to a sell-off in stocks like Newmont.

Marathon Asset Management Ltd sold 126,742 shares of Newmont, cutting its stake by 42.0% to 174,701 shares. Such a significant reduction in institutional investment can signal a lack of confidence in the company's future performance, which can lead to a sell-off in the stock.
