一个人对某个资产或市场"为什么会涨/跌/横"的完整理由链条，是所有判断的出发点。A thesis is the full chain of reasoning behind why someone believes an asset or market will move in a particular direction — the starting point for any judgment.
看一个人的 thesis，能知道他的判断建立在哪些前提上；一旦某个前提被现实推翻，整条逻辑就需要重新审视，而不是死守原来的结论。Examining someone's thesis reveals which assumptions their view depends on. When reality invalidates one of those assumptions, the entire reasoning chain deserves a fresh look — not a stubborn defense of the original conclusion.
