Expert Network Calls

Expert networks offer investors in-depth discussions with subject matter experts. Call volume is higher for hard-to-value firms, such as young, technology-oriented, and high intangible asset firms. Calls emphasize non-financial news, with topic distribution predicting future related news coverage in the following months. We find that expert call tone predicts abnormal future stock returns, stock sentiment, and earnings surprises, especially for negative calls and when tone diverges from prevailing market sentiment. Expert call activity also predicts informed trading and improved price efficiency. Our findings highlight expert networks as a valuable alternative information source, helping investors identify and interpret value-related firm information.
