Abstract

In our paper we outline some empirical evidences about aggregated analyst errors, i.e. systematic differences between consensually forecasted and observed prices. In particular, we find that the error is independent from the amount of analysts covering the stock, while industry plays an important role, although an error is bigger for growth companies. We also confirm previous evidence that price estimates aggregation over an index result in better estimates performance. Along with that, EPS is predicted better than price itself. Based on mentioned facts we deduce that the main reason for poor performance of analysts should likely be in their disability to choose correct discount rate. Our result contributes to literature on efficient market hypothesis, to studies of stock market analyst accuracy and to surveys of best/worst practices of equity valuation. В статье приводятся эмпирические свидетельства об ошибках в агрегированных прогнозах аналитиков рынка акций, т.е. систематических различиях между прогнозируемыми и наблюдаемыми ценами. В частности, мы показываем, что ошибка не зависит от количества аналитиков, покрывающих акцию, в то время как отрасль, в которую входит акция, играет существенную роль; вместе с тем компании роста в целом имеют большую ошибку по сравнению с компаниями стоимости. Мы также подтверждаем предыдущие свидетельства того, что сложение оценок аналитиков в индекс позволяет сделать оценку более точной(т.е. индекс предсказывается лучше отдельных акций). Вместе с тем EPS прогнозируется лучше, чем цена. На основании указанных фактов мы предполагаем, что основная причина неточности в прогнозах, скорее всего, заключается в неспособности аналитиков выбирать правильную ставку дисконтирования. Наш результат является вкладом в литературу одновременно по теории эффективного рынка, исследования точности аналитиков рынка акций и лучших/худших практик оценки капитала.
