Insider Activity Analysis
Net Insider Sentiment
Strong bearish signal with $12.97M net selling. Heavy insider selling may indicate concerns about valuation or near-term prospects.
Buy/Sell Ratio
Very poor ratio. Heavy selling with minimal buying suggests insiders may be concerned about valuation or outlook.
Recent Trend (3 Months)
Heavy recent selling activity. Recent insider sales notably exceed purchases—may warrant investigation into company developments.
Insider Participation
4 insider sellers vs. 1 buyers. Widespread selling across multiple insiders may signal concerns.
Insider Activity Insight
Multiple red flags: Heavy selling, numerous sellers, and continued recent selling create a concerning pattern. Investigate fundamental drivers and consider whether company guidance or industry conditions have deteriorated.
