The real issue is you're not sure how it's going to go. The benchmark you're starting from isn't the best-case scenario, it's somewhere in the middle. Most of the risk we talk about in finance is risk associated with price uncertainty—the stock price, the option price, the price of a bond. The uncertainty of prices reflects the uncertainty in the world, but we concentrate on price uncertainty

实际问题在于，你不知道股价走势。你一开始所用的基准不是最佳情况（？？？），而是介于两者之间。我们在金融领域所谈论的风险大多是与价格不确定性有关的风险：股票价格、期权价格和债券价格。价格不确定性反映了现实世界的不确定性，不过我们关注的是价格不确定性。
