问题如下：
Which of the following statements about expectations and asset values is not correct:
选项：
A.
Asset values depend on past cash flows.
B.
Information that has been anticipated is
already reflected in asset prices.
C.
Information that is different from what was
expected constitutes real news that requires expectations to adjust.
解释：
考点：expectations and asset values
解析：选项A的说法错误，资产的价值取决于预期未来现金流，而不是过去现金流。
选项B和C的说法均正确，预期的信息已经反映在资产价格中；如果真实的情况出现了与预期不同的部分，我们需要对预期进行调整，以反映在资产价格中。
这个是哪个知识点，在哪个ppt上
