Les marchés sont devenus fous : ça va mal finir ?

The speaker discusses the current market's unprecedented and rapid rise, questioning its fundamental explanations. They suggest the surge is driven by short sellers being trapped, forced to buy back positions to limit losses, creating a self-reinforcing upward trend without significant corrections. This phenomenon is described as rarely seen, unlike previous rebounds. The speaker references Paul Tudor Jones, who compares the current situation to 1999, before the 2000 crash, hinting at a potential impending fall. However, the speaker emphasizes that the opinions of experts like Jones or Warren Buffett are less important than having a robust, systematic investment method. They highlight their own portfolio's performance of 19% in one month and 30% year-to-date, achieved through a strategy based on the scientific anomaly of momentum, with clear entry and exit rules. The core message is that attempting to rationalize an irrational market or guess its movements is futile. Instead, adopting and strictly adhering to a proven method, regardless of expert opinions or market sentiment, is key to success. The speaker notes that most of their students are profitable using this approach, demonstrating its effectiveness even when the market appears overvalued or prone to collapse.
