This document discusses measuring trust indicators for investors. It proposes using a framework to attribute investor behaviors to trust by examining conditions that contribute to trust formation. The framework identifies five conditions for trust: factual sources, motive forces, proficiencies, risk transference, and interpretive sources. It argues that understanding these conditions provides valid insights into investor trust beyond just surveys or behaviors alone. The document aims to help organizations, issuers, regulators optimize processes to improve investor trust and confidence.
