Why COO stock is down today
COO stock fell 14.67% to $54.17 in a single session, marking the Cooper Companies' largest loss in recent memory. The drop followed the company's announcement that it would not sell its CooperSurgical division and its decision to cut full-year 2026 revenue and earnings per share guidance. These developments prompted immediate market concern over near-term growth prospects and triggered a sharp selloff.
What Happened
The Cooper Companies announced it would maintain ownership of its CooperSurgical business, reversing earlier speculation that a potential sale was imminent. This decision, combined with downward guidance for FY26 revenue and EPS, led to a significant reassessment of the company's value proposition. The stock hit a 52-week low during the session, reflecting investor disappointment. Mizuho analysts responded by lowering their price target for COO due to ongoing sales softness. Meanwhile, a securities fraud investigation was announced, adding further uncertainty and prompting legal inquiries from shareholders who may have suffered losses.
What The Data Shows
COO has experienced a steep price decline of 22.2% over the past eight trading sessions, moving from $70.09 to $54.54. The stock currently trades at a P/E ratio of 53.6, with a market cap of $13.2B. Despite a recent report of record free cash flow and a $307 million tax benefit, the company's net margin remains at 5.6%, and its beta of 0.82 indicates lower volatility than the broader market. The 52-week trading range is $58.89 to $89.83, with the current price near the lower end. No unusual options activity or insider filings were reported in the last 90 days, though recent congressional trades included several small purchases by Rep. Gilbert Cisneros and a sale by Donald J. Trump.
What To Watch
The company's upcoming earnings report will be closely watched for further clarity on its strategic direction and financial performance. Investors should also monitor any developments related to the ongoing securities investigation and potential regulatory actions.
