Sousa Mauad Bruno bought 61,552 shares of Aura Minerals Inc. (AUGO) at $83.58 for a total transaction value of $5,144,652.
This trade scores 100/100, indicating very high conviction. Large open-market purchases by C-suite executives with minimal noise factors are rare and historically correlated with positive 90-day forward returns.
