XBP drew concentrated buying — XBP was the notable cluster-buying name: 5 insiders bought about $2.4M. Jonovic Andrej was also flagged for an executive purchase of about $89.1K in XBP. XBP Jonovic Andrej
TYRA purchase led buying scale — Over the past 14 days, Ra Capital Management, L.p. made the largest reported purchase, buying about $200.0M of TYRA.
