问题如下：
With respect to utility theory, the most risk-averse investor will have an indifference curve with the:
选项：
A.most convexity.
B.smallest intercept value.
C.greatest slope coefficient.
解释：
C is correct.
The most risk-averse investor has the indifference curve with the greatest slope.
凸度就是二阶导，R = U + 1/2xAxsigma2 的二阶导就是A。
所以，越 risk averse，A就越大，凸度就越大。所以 A选项正确。
为什么不选A？

C.greatest slope coefficient. is correct.The most risk-averse investor hthe infferencurve with the greatest slope. 其中有一个回答就说“这题问的是most risk-averse investor的情况，他代表了极度厌恶风险的人群。所以对于这类人群，他们的无差异曲线不仅是凸的，而且凸的很明显；每一单位风险的增加会要求更高的收益率的增加。所以他们的无差异曲线斜率很大。”凸的很明显，不就表示Convexity很大么？就感觉 A和C表达是一个意思，麻烦老师再讲解一下

C.greatest slope coefficient. is correct.The most risk-averse investor hthe infferencurve with the greatest slope. 看了之前的解答，还是有点疑惑，a里面的most convexity难道不是这个最风险厌恶的投资者跟其他投资者比起来他是最convexity的吗？感觉之前的回答里老师的说的不是很清楚，麻烦老师讲一下。丹丹_品职答疑助手 · 超过 1 年前嗨，从没放弃的小努力你好同学你好，可以借用效用理论的公式U=E（r）-0.5*A（stanrv）^2,所以对于同一个投资者convexity是相同的
