Insider Activity Analysis

Net Insider Sentiment

Bearish

Strong bearish signal with $958.94M net selling. Heavy insider selling may indicate concerns about valuation or near-term prospects.

Buy/Sell Ratio

0.05:1

Very poor ratio. Heavy selling with minimal buying suggests insiders may be concerned about valuation or outlook.

Recent Trend (3 Months)

$7.90M

Heavy recent selling activity. Recent insider sales notably exceed purchases—may warrant investigation into company developments.

Insider Participation

Balanced

5 insider buyers and 5 sellers. Equal participation suggests mixed or neutral insider views.

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.
