We present evidence consistent with markets failing to properly price information in seasonal earnings patterns. Firms with historically larger earnings in one quarter of the year (“positive seasonality quarters”) have higher returns when those earnings are usually announced. Analysts have more positive forecast errors in positive seasonality quarters, consistent with the returns being driven by mistaken earnings estimates. We show that investors appear to overweight recent lower earnings following positive seasonality quarters, leading to pessimistic forecasts in the subsequent positive seasonality quarter. The returns are not explained by risk-based explanations, firm-specific information, increased volume, or idiosyncratic volatility.

Using a set of proprietary records, we examine who consumes quarterly earnings conference calls and under which circumstances the calls are consumed. While there is significant interest in calls by institutional investors and sell-side analysts, we find that investors who do not hold a position in the firm are a leading consumer. We show that buy-side non-holders who consume calls are more likely to hold positions in competitors and to purchase the stock in the future. In addition, many investors who hold large positions only consume calls periodically. We also document a benefit of consuming calls by finding that the consumption of calls is associated with more informed trading decisions. Overall, our investigation illuminates the actual consumption of conference calls by different consumers and the potential benefits of consuming additional firm disclosures.
