Core Viewpoint - The article discusses the phenomenon of "small essays" in the stock market, highlighting their role in manipulating stock prices and the challenges in regulating such activities [4][35][37]. Group 1: Characteristics of "Small Essays" - "Small essays" are essentially rumors or unverified information that can significantly impact stock prices, often exploiting the curiosity and speculative nature of retail investors [6][12]. - They can be categorized into five types: policy rumors, company operations, fund movements, market sentiment/conspiracy theories, and over-interpretation of public information [9][8]. - The spread of these rumors typically begins in social media circles, where they are crafted to maximize impact and reach [11][19].
