Renowned stock picker Serenity has experienced a significant 49.4% drawdown in his portfolio, primarily due to investments in AI bottleneck and restricted areas, as well as small-cap stocks. Despite this setback, Serenity's early entry points suggest that the drawdown mainly affects his profits rather than his initial capital. Serenity remains optimistic, indicating a tolerance for volatility and predicting a revenue inflection point in the latter half of 2027.
