Familiarity bias and earnings-based equity valuation

This study examines whether investors’ familiarity bias affects their earnings-based equity valuation. Building on theoretical and empirical findings from prior studies, we hypothesize that familiarity bias may reduce the earnings-based equity valuation of foreign firms. We also hypothesize that the perceived link between current earnings surprises and future operating cash flows is one channel through which familiarity bias affects earnings-based equity valuation. Using the setting of the earnings announcements of U.S.-listed non-U.S. firms and U.S. firms matched by industry, year, and firm characteristics, we find that U.S. investors discount the earnings response coefficient of non-U.S. firms relative to that of U.S. firms by 46%. Using analysts’ earnings forecast revisions immediately following the earnings announcements as the proxy for the market-perceived link between current earnings surprises and future operating cash flows, we find that analysts significantly discount the link for non-U.S. firms relative to U.S. firms. Both discounts exist only in the subsamples of non-U.S. firms toward which U.S. investors have a higher degree of familiarity bias. Thus, we provide empirical evidence of the effect of the familiarity bias on earnings-based equity valuation and the channel through which it affects equity valuation.
