| Abstract: | 分析師之盈餘預測仍是資本市場上重要的評斷依據，因而本文採用2018年1月至2023年八月之美國市場資料，並參考Diether, Malloy, and Scherbina (2002)定義之分析師盈餘預測分散度，並再使用三項財務指標（市值、淨值市價比及動量），建構投資組合，再進行Fama-Macbeth Regression 兩步驟橫斷面回歸分析，來探討研究分析師盈餘預測之分散度對於股票報酬率，各項因子之顯著性。
本研究發現分析師盈餘預測之分散度對於股票報酬率存在反向關係，且小公司優於大公司，且在加入特定財務指標後，能將股票區分為不同類型，如價值股及成長股，也使分析師盈餘預測之分散度有不同表現。另外，在2020年1月至2022年2月不存在此關聯性。整體而言，分析師之預測行為仍相當有效，分析師盈餘預測具有一致性，分散度低時，未來股票報酬率較高。
Analysts' earnings forecasts remain an important benchmark in capital markets. Therefore, this paper utilizes data from the U.S. market between January 2018 and August 2023, referencing the definition of analyst earnings forecast dispersion by Diether, Malloy, and Scherbina (2002). Using three financial indicators (market capitalization, book-to-market ratio, and momentum), we construct investment portfolios and conduct a Fama-Macbeth two-step cross-sectional regression analysis to explore the relationship between the dispersion of analysts' earnings forecasts and stock returns.
Our study finds an inverse relationship between the dispersion of analysts' earnings forecasts and stock returns, with small-cap companies outperforming large-cap companies. By incorporating specific financial indicators, we can categorize stocks into different types, such as value and growth stocks, revealing varied performances in the dispersion of analysts' earnings forecasts. Additionally, this relationship does not hold between January 2020 and February 2022. Overall, analysts' forecasting behavior remains quite effective, with lower dispersion in analysts' forecasts corresponding to higher future stock returns. |
