Not all words are equal: Sentiment and jumps in the cryptocurrency market
研究了加密货币价格跳跃与新闻情绪的关系，发现信息发布增加跳跃概率，且特定情绪维度（如情绪或市场基本面相关）更易引发跳跃，不同币种敏感性不同。
This paper analyzes the relationship between price jumps and news sentiment in cryptocurrencies. We detect jumps at the intraday level and correlate their occurrence with sentiment-related events through logistic regressions. We show that the release of information increases the probability of price jumps. By examining the content of news stories, we find that sentiment dimensions limited to emotions or related to market fundamentals have more potential to result in price jumps than others, suggesting that “words are not all created equal”. Jump sensitivity to news sentiment varies across different coin characteristics.
