Despite research in sentiment-driven finance, many studies focus on sentence-level classification, overlooking its practical application in trading. This study bridges that gap by evaluating sentiment-based trading strategies for generating positive alpha. We conduct a backtesting analysis using sentiment predictions from three models (two classification and one regression) applied to news articles on Dow Jones 30 stocks, comparing them to the benchmark Buy\u0026Hold strategy. Results show all models produced positive returns, with the regression model achieving the highest return of 50.63% over 28 months, outperforming the benchmark Buy\u0026Hold strategy. This highlights the potential of sentiment in enhancing investment strategies and financial decision-making.","short_abstract":"Sentiment analysis, widely used in product reviews, also impacts financial markets by influencing asset prices through microblogs and news articles.
