Executive Summary
Two PTCT insiders — a director and the EVP & CLO — sold a combined $138K in shares over a one-week window. The sales are small in absolute terms and relative to market cap, and the CLO's sale is likely tax-withholding related given the odd lot size. This cluster does not convey material negative information.
