Abstract
This paper examines the accuracy of target price forecasts made by sell-side analysts, focusing on predicting target price accuracy using machine learning approaches. Utilizing a dataset of target price forecasts for U.S. listed companies from 1999 to 2021, we employ ensemble methods and incorporate market-level, firm-level, and analyst-level information to predict target price accuracy in terms of target price errors and target price achievement. The long-short portfolio constructed based on our predictions significantly outperform the benchmark in terms of cumulative return and Sharpe ratio.

2 According to Hao and Skinner (Citation2022), most analyst reports state that the forecasted 12-month dividends have been discounted in the 12-month target prices. The target prices do not include dividends to be paid within a year. Moreover, the dividend payout ratio has been included in the firm characteristics.
3 The I/B/E/S database provides target price data dating back to July 1999.
4 Sensitivity: the “true positive rate,” or the percentage of positive cases the model can detect; specificity: the “true negative rate,” or the percentage of negative cases the model can detect.
5 The number of estimators “n_estimators” is reduced from 500 to 150 to mitigate the computation time.
6 For example, if there are 2024 target prices in a certain month, we include 202 stocks in both the long and short segments.
7 For gradient boosting regression model, we use squared error as the loss function to be optimized.
8 For gradient boosting classification model, we use binomial deviance (negative log-likelihood) as the loss function to be optimized.
