Abstract
This study examines the effect of lottery characteristics on analysts’ earnings forecasts. We find that analysts are more optimistic for lottery firms. Compensation incentives and access to private information from management are key drivers for analysts’ optimistic forecasts. The optimism of earnings forecast for lottery stocks decreases with analysts’ general and firm-specific experience. Our findings suggest that both behavioral biases and rational incentives help explain analysts’ optimism toward lottery stocks. Moreover, investor sentiment positively affects the effect of lottery characteristics on analyst optimism. Firm-specific risk and market uncertainty enhance the effect of lottery characteristics on analysts’ earnings forecast bias. The level of optimism on lottery stocks increases during up markets and economic expansion.

Notes
Kumar (2009) method was widely adopted in the literature. For example, Meng and Pantzalis (2018) classify lottery-type stocks as those in the lowest 50th stock price percentile, the highest 50th idiosyncratic volatility percentile, and the highest 50th idiosyncratic skewness percentile. Kumar et al. (2016), Chen et al. (2021a, b), Gong et al. (2021), and Kwon et al. (2022) use Kumar’s (2009) composite lottery index based on idiosyncratic volatility, idiosyncratic skewness, and stock price to proxy for stocks’ lottery-like characteristics. Moreover, some researches use the maximum daily return (MAX) as a proxy for lottery-like features (e.g., Bali et al., 2011, 2017; Agarwal et al. 2022). Gould et al. (2023) measure a stock’s lottery-like characteristics in terms of idiosyncratic volatility, idiosyncratic skewness, and stock price (Kumar 2009), a stock’s maximum single-day return during a month (Bali et al. 2011) as well as a low return for the past month. To the extent that maximum daily return and a low return for the past month are a short-term (one month) proxy for lottery-like characteristics, this study follows Kumar (2009), Kumar et al. (2016), Chen et al. (2021a, b), Gong et al. (2021), and Kwon et al. (2022) and use stock price, idiosyncratic volatility, and idiosyncratic skewness to measure longer period (previous 12 months) lottery-like characteristics.
Chu and Zhai (2021) posit that analysts make more optimistic earnings forecasts of high distress risk because they underestimate the implication of their poor performance.
Our results remain qualitatively unchanged when the volatility of earnings is measured by the standard deviation of earnings per share (VAREARN) in the preceding four quarters.
We first classify lottery and non-lottery stocks, and then exclude firms without complete data. Therefore, the proportion of lottery observations in our sample is not 12.5% (0.5*0.5*0.5).
The marginally negative coefficient of ROA is consistent with Brown (2001), who argues that losses make analysts’ forecast less accurate. Higher number of analyst following (COVERAGE) indicates more intense competition among analysts, and thereby provides more incentives for analysts to make more optimistic forecasts to cater to managers.
