American Shared Hospital Services shares rise 14.90% intraday after Medline's potential $50 billion IPO filing.

American Shared Hospital Services rose 14.90% intraday, with the healthcare sector experiencing a mix of positive and negative news. The appointment of a healthcare industry veteran to Lucid Diagnostics' Board of Directors and the strategic collaboration between Guardant Health and Quest Diagnostics to offer a blood-based screening test for colorectal cancer are positive developments. However, regulatory fears and concerns about potential tariffs on medical equipment and robotics, as well as the decline in shares of pharmaceutical companies like Kenvue and Gerresheimer, may have contributed to the overall market sentiment.
