speculation
意味: The act of forming opinions or theories without firm evidence; in finance, the practice of investing in risky assets in the hope of making large profits.
Speculation has two main uses. In intellectual discourse, it refers to conjecture or theorising beyond what the evidence firmly supports. In finance, it describes high-risk trading aimed at profiting from short-term price fluctuations rather than long-term value. Common collocations include 'idle speculation,' 'media speculation,' and 'property speculation.'
