Insider Activity Analysis

Net Insider Sentiment

Bearish

Strong bearish signal with $2.00M net selling. Heavy insider selling may indicate concerns about valuation or near-term prospects.

Buy/Sell Ratio

0.00:1

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

Recent Trend (3 Months)

$2.00M

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

Insider Participation

High Selling

1 insider sellers vs. 0 buyers. Widespread selling across multiple insiders may signal concerns.

Persistent selling pressure: Consistent insider selling with weak buy/sell ratio suggests insiders may be capitalizing on current valuation. Exercise caution and review recent earnings quality and management commentary.
