Insider Activity Analysis

Net Insider Sentiment

Bullish

Moderately bullish with $545K net buying. Insiders show cautious optimism through measured share purchases.

Buy/Sell Ratio

1.06:1

Positive buy/sell ratio. Buying exceeds or matches selling, indicating net positive insider sentiment.

Recent Trend (3 Months)

$7.05M

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

Insider Participation

Moderate Selling

4 insider sellers vs. 3 buyers. More insiders selling than buying suggests cautious or negative sentiment.

Insider Activity Insight

Broad-based insider buying: When multiple insiders independently decide to purchase shares, it often reflects genuine confidence rather than coordinated optics. This pattern deserves attention, especially if buying followed a price decline.
