Insights

Financial Analyst

TL;DR: Minor insider purchase; bullish signal but immaterial in size.

This Form 4 shows a director adding roughly $15,000 worth of stock (4,189 × $3.58). While insider buying is directionally positive—indicating personal confidence—the volume represents a small fraction of both trading liquidity and total shares outstanding, so the market impact should be limited. No derivative grants or sales were reported, suggesting the transaction is straightforward equity accumulation.
