Automated Earnings Forecasts: Beat Analysts or Combine and Conquer?

Abstract: Prior studies attribute analysts’ forecast superiority over time-series forecasting models to their access to a large set of firm, industry, and macroeconomic information (an information advantage), which they use to update their forecasts on a daily, weekly or monthly basis (a timing advantage). This study leverages recently developed mixed data sampling (MIDAS) regression methods to synthesize a broad spectrum of high frequency data to construct forecasts of firm-level earnings. We compare the accuracy of th… Show more

“…In the Operations Management literature, understanding the benefits/costs of allowing expert input in operational decision-making has been attracting interest in various application areas. For example, it has been examined in the context of horizontal multimarket coordination (Anand and Mendelson 1997), ordering behavior in retail stores (Van Donselaar et al 2010), capacity supply decisions in service operations (Campbell and Frei 2011), sales forecasting (Osadchiy et al 2013), price setting (Phillips et al 2015), and earnings forecasting (Ball and Ghysels 2018). In healthcare settings, Kim et al (2015) examine physicians' hospital unit admission decisions and show that allowing physician input in their data-driven decision making can help improve the system's performance.…”

“…Quanto às discussões recentes sobre a reavaliação da superioridade dos analistas, este trabalho é relevante no sentido de acompanhar a discussão da literatura internacional, que indica que a superioridade dos analistas não é irrestrita e que, portanto, é necessário avaliar quando e sobre quais circunstâncias as estimativas dos analistas são mais acuradas do que as estimativas dos modelos de séries temporais (BALL, GHYSELS, 2017;BRADSHAW et al, 2012;LACINA, LEE, XU, 2011;LOREK, PAGACH, 2014).…”

“…Contudo, após um período inicial de desinteresse por essa linha de pesquisa, alguns estudos passaram a reavaliar a superioridade dos analistas de mercado e a discutir quando e sobre quais circunstâncias as estimativas dos analistas de mercado seriam superiores às previsões dos modelos de séries temporais (BALL, GHYSELS, 2017;BRADSHAW et al, 2012;LACINA, LEE, XU, 2011;LOREK, PAGACH, 2014).…”
