问题
A "random walk" occurs when______.
选项
A、stock price changes are random but predictable
B、stock prices respond slowly to both new and old information
C、future price changes are uncorrelated with past price changes
D、past information is useful in predicting future prices
答案
C
解析
答案为C项。random walk“随机走势”。由法国数学家路易斯·巴克雷首先提出的。该观点认为,股价是对各种信息做出反应的结果,由于各方面信息随机进入股市,因而股价是随意变动的。随机走势意味着股票价格是不可预测的,不论是用过去的价格变动还是任何其他的数据资料。故本题选C项。
