报告摘要：
We create a market-level analyst sentiment index from firm-level textual tones in analyst reports and compare it to existing investor sentiment indices. High investor sentiment typically corresponds with high analyst sentiment, leading to market overpricing. Our analysis shows that the analyst sentiment index negatively predicts aggregate stock market return. Existing investor sentiment indices have been relatively flat in recent years, casting doubt on their ability to reflect underlying investor sentiment. Conversely, the analyst sentiment index still fluctuates and may better reflect underlying investor sentiment. Additionally, analysts may give less favourable tones when manager sentiment is high, which can mitigate inefficient over-investment due to managers' overoptimistic views.
