Prospect Capital is trading at $1.60, up 7.38% in pre-market amid an amended ownership filing disclosing CEO John Barry’s share purchases. - Barry disclosed acquiring about 4.05 million shares between May 21 and October 20; 3.95 million were open-market purchases. - The amended filing was submitted after the October 20 close. - The filing is a plausible catalyst for the October 21 pre-market move, but no source confirms it caused the rise. Index moves were modest, and no other verified company-specific announcement explaining the gain surfaced.
