Actionable Insight ▲ Bullish

The CEO/CFO's concentrated buying over a short window suggests management sees value at current levels. Monitor for upcoming clinical or regulatory catalysts (e.g., FDA updates on GP2 vaccine trial) that could drive near-term upside. The small absolute size limits the signal's strength, but the pattern is worth watching.
