Processing Fluency and Investors’ Reactions to Disclosure Readability

The SEC's emphasis on the use of plain English is designed to make disclosures more readable and more informative. Using an experiment, I find that more readable disclosures lead to stronger reactions from small investors, so that changes in valuation judgments are more positive when news is good and more negative when news is bad. Drawing on research in psychology to explain this result, I predict and find that processing fluency from a more readable disclosure acts as a subconscious heuristic cue and increases investors’ beliefs that they can rely on the disclosure. Although I do not find that more readable disclosures directly increase perceptions of management credibility, I do find evidence of an indirect effect operating through feelings of processing fluency. In supplemental analyses, I find that investors who receive more readable disclosures revise their valuation judgments to be less extreme when they are explicitly made aware of the potential for variation in readability. I discuss potential explanations for these revised valuation judgments.
