We construct sentiment indices for 20 countries from 1980 to 2019. Relying on computational text analysis, we capture specific language like “fear”, “risk”, “hedging”, “opinion”, and, “crisis”, as well as “positive” and “negative” sentiments, in news articles from the Financial Times. We assess the performance of our sentiment indices as “news-based” early warning indicators (EWIs) for financial crises. We find that sentiment indices spike and/or trend up ahead of financial crises.

News sentiment has been empirically observed to have impact on financial market. However, finding a clear predictor of market returns using news sentiment remains a challenging task. This study investigates the relationship between news sentiment and cumulative market returns and volatility. We propose two methods for measuring the abnormal level of news sentiment, i.e. sentiment shocks and sentiment trend, and we analyze its relationship with market movements. The results show that abnormal levels of news sentiment are significant in predicting future market cumulative return and implied volatility of the S&P 500 index. Comparing the two methods, we find that the sentiment trend method demonstrates better performance than the sentiment shock method. In addition, our findings suggest that the strategy generated based on the abnormal news sentiment methods outperforms the buy-and-hold strategy through back-testing over the same time period.

Digitization of news articles and the advancement of computational intelligence applications have led to a growing influence of news sentiment over financial markets in recent years. News sentiment has often been used as a proxy for gauging investor's sentiment and reflecting the aggregate confidence of the society toward future market. Previous studies have primarily focused on elucidating the unidirectional impact of news sentiment on market returns and not vice versa. In this study, we document the presence of a significant feedback effect between news sentiment and market returns across the major indices in the U.S. financial market. We find that news sentiment exhibits a lag-4 effect on market returns and conversely market returns elicit consistent lag-1 and lag-2 effects on news sentiment. This aligns well with our intuition that news sentiment drives trading activity and investment decisions. In turn, heightened investment activity further stimulates involuntary responses, which manifest in the form of more news coverage and publications. The evidence presented highlights the strong correlation between news sentiment and market returns, and demonstrates the potential benefits of advancing knowledge in sentiment modeling and its interaction with market movement.

The stock market is affected by sentiment. The question is, however, how to quantify this effect on asset prices. By utilizing the unique RavenPack Sentiment Index, a news-based proxy for market sentiment, this paper intends to address this issue empirically by exploring the pricing implications of a stock's exposure to market sentiment. We also explore a concept we coined as "news beta" or the sensitivity of stock returns to changes in market sentiment as reported by the media. After controlling for traditional factors, news beta is found to have strong return predictability over 6 and 12 month horizons. The evidence from this research suggests that market sentiment data is still an untapped source of alpha in financial markets.

An examination of digital evidence from initial collection through to presentation of evidence in court. Electronic discovery represents a new paradigm for litigators. Digital information, from email and attachments, to documents created on word processors, to instant messaging communications and "Twitters", is what comprises discovery today. Preserving the chain of custody from collection of this digital evidence to presentation in court is imperative. Electronic courtrooms are becoming more common to allow presentation of evidence in electronic format and this will continue, not only for large, document heavy cases, but for all litigation matters in the future. Australian courts continue to develop practical standards to ensure consistency of data and documents during discovery and at trial. This book is a must-read for all litigators, students and academics, especially those who have not dealt with electronic documents during discovery.
