The user @bubbleboi alleges that the account Serenity is conducting "pump and dump" schemes on micro-cap stocks, specifically highlighting Fluence Energy Inc (FLNC). While Serenity expresses a bullish outlook on FLNC due to potential contracts with MSFT and AMZN, @bubbleboi counters this by highlighting the company's negative financial metrics, including a -1.62% profit margin, -$18.45M EBITDA, and -$236.03M operating cash flow. FLNC was recently trading around $23.03, showing significant volatility and a year-to-date decline.
