风险性是股票的特征之一，下列关于股票风险性特征的说法有误的是( )
A．股票风险的内涵是股票投资收益的不确定性，或者说实际收益与预期收益之间的偏离程度
B．投资者在买入股票时，对其未来收益会有一个估计，但事后看，真正实现的收益可能会高于或低于原先的估计，这就是股票的风险
C．风险不等于损失，高风险的股票可能给投资者带来较大损失，也可能带来较大的未预期收益
D．风险本身是一个中性概念，但是，高风险一般对应着高收益，因此投资者一般喜欢投资那些风险较高的股票
参考答案：D
解析： 风险本身是一个中性概念，但是，多数理性的投资者厌恶风险，如果要诱导投资者投资那些风险较高的股票，就必须提供更高的预期收益，这就是“高风险高收益”的含义。
