QDEL Rallies 31.7% in Three Months: Can the Stock Keep Climbing Higher?

QuidelOrtho (QDEL) has seen its stock rally 31.7% in three months due to resilient core diagnostics growth and cost-saving initiatives. However, the company faces headwinds from a sharp slowdown in China, weakening respiratory demand, and a cut in its 2026 revenue and earnings guidance, along with a heavily leveraged balance sheet. The stock currently holds a Zacks Rank #5 (Strong Sell), indicating potential challenges in sustaining its recent gains.
