Denison Mines Corp. Hits Day High with Strong 5.75% Intraday Surge

Denison Mines Corp. has experienced a significant uptick in its stock performance, gaining 5.75% on February 24, 2026. The stock reached an intraday high of CAD 5.91, reflecting a strong day of trading for the midcap company in the minerals and mining sector. Over the past week, Denison Mines has shown impressive growth, with a 14.15% increase, significantly outperforming the S&P/TSX 60, which rose by only 2.02%. The company's one-month performance stands at 10.3%, while its year-to-date performance is notable at 61.81%. Over the last year, Denison Mines has achieved a remarkable 166.52% increase, far exceeding the S&P/TSX 60's 27.5% gain. Despite these positive short-term trends, the company faces challenges in its long-term fundamentals, including operating losses and a weak ability to service its debt. The stock's performance contrasts with its declining net sales and operating profit over the past five years. Investors should remain aware of these underlying factors as they monitor Denison Mines Corp.'s market activity.
