The recent insider sale of SI-BONE shares and the absence of insider purchases over the past year might worry investors. The low level of insider ownership and recent selling activity could indicate a misalignment between insiders and other shareholders.

SI-BONE's high P/S ratio is justified by its superior revenue growth and future prospects. Shareholders are confident in the company's future revenues, keeping the share price buoyant.

Multiple insider stock sales over the past year, including a notable sale at the current price, suggests reduced confidence in the firm's equity. The lack of insider purchases enhances these doubts about prospective share performance. Even with insider ownership, the ongoing sell-off hints at a careful approach to buying the company's stock.

The company's future could potentially bright despite underperformance, due to revenue growth. However, past unprofitability may have affected investors' sentiment. Note the 3 warning signs for SI-BONE as possible risks.
