又炒火一只妖股，继“咆哮小猫”后 美股有了新“带头大哥”……

Core Viewpoint - The surge in stock prices for companies like Nextdoor and Opendoor is driven by retail investors and hedge fund manager Eric Jackson, who is seen as a leader among these investors [1][5]. Group 1: Nextdoor's Performance and Potential - Nextdoor's stock price increased by 25.87% in one day, reaching a peak increase of nearly 50%, marking its largest intraday gain in over four years [1][3]. - The company, which went public through a SPAC merger in 2001, focuses on community-based social media, allowing users to connect with neighbors and access local news [3][4]. - Despite revenue growth, Nextdoor has struggled with profitability, but Jackson believes it is one of the most misunderstood platforms in the market, particularly regarding its AI potential [3][4]. Group 2: Eric Jackson's Influence - Jackson argues that Wall Street traders underestimate Nextdoor, viewing it primarily as a low-growth local advertising business, while it actually possesses a unique identity graph valuable in the AI era [4]. - He emphasizes the platform's core strengths, including over 100 million verified household users and minimal bot accounts, suggesting that Nextdoor's current stock price of around $2 may represent a pivotal moment for the company [4]. - Jackson has previously driven significant stock price increases for other meme stocks, such as Opendoor, which saw a rise of over 360% this year, largely following his recommendations [5].
