The market is a “collection of uncertainties,” not a “predictable machine.” The market is woven from the expectations, emotions, and capital flows of countless participants. Its essence is a game of probabilities, not deterministic causality. No one can always accurately predict short-term rises and falls (including Buffett and Soros). The key to profit is not “correct predictions,” but “repeated actions under a probabilistic advantage” (such as a positive long-term win rate plus a positive expectancy based on the risk-reward ratio). Wisdom: abandon the obsession with “precise predictions,” and shift toward “dealing with uncertainty”—using rules (such as stop-loss and position management) to hedge risks, and employing probabilistic thinking to seize opportunities.
