  • Insider buying after a steep drop may attract speculative interest, but the dollar amount is relatively small.

    investing.com · Jul 31, 2026

  • Insider buying is a modest bullish signal, but the article’s main tradable catalyst is the disclosed Phase III protocol and manufacturing approvals.
