Bearish

Slightly bearish with $3.49M net selling. Selling modestly exceeds buying, which could be routine diversification rather than concern.

Moderately negative ratio. Selling is roughly double the buying, which may be routine or signal caution.

Recent Trend (3 Months)

$159K

Very strong recent buying momentum. Recent insider purchases significantly outpace sales, suggesting near-term optimism.

Insider Participation

Moderate Buying

4 insider buyers vs. 3 sellers. More insiders buying than selling indicates positive sentiment.
