What You Say and How You Say It Matters: Predicting Stock Volatility Using Verbal and Vocal Cues (P19-1)
Copied to clipboard
| Challenge: | Existing studies have shown that textual information in a firm’s financial statement can be used to predict its stock’s risk level. |
| Approach: | They propose to model CEO’s verbal (from text) and vocal (from audio) information in a conference call. |
| Outcome: | The proposed model reduces the error rate by comparing CEO’s verbal and vocal information in a conference call with other models. |

Forecasting Earnings Surprises from Conference Call Transcripts (2023.findings-acl)
Copied to clipboard
| Challenge: | Earnings conference calls contain over 5,000 words of text and large amounts of industry jargon . this length and domain-specific language present problems for generic pretrained language models. |
| Approach: | They propose a task of predicting earnings surprises from earnings call transcripts and propose linguistic models that use a long document dataset to test financial understanding. |
| Outcome: | The proposed model can predict earnings surprises from earnings conference calls with reasonable accuracy and shows that it is possible to interpret the data with different interpretability methods. |
