Despite the company's less than stellar revenue forecasts, Peijia Medical's P/S ratio remains high. This could pose a risk to shareholders and potential investors as the P/S could fall if revenue sentiment doesn't improve, potentially leading to significant losses.

The sale of shares by insiders might suggest future weakness in Peijia Medical's stock performance. High insider ownership is typically positive, but share selling isn't viewed favorably. Be cautious of potential risk factors facing Peijia Medical.
