这一题的A选项为什么是对的 statistical 和 trading rule 不是属于技术分析吗 是属于基本面分析吗?

同学你好。
这里说的统计学和trading rule都是为了验证技术分析的假设是否存在。如果存在,说明没有weak-form。所以可以用来test(检验)weak-from。Tests of whether securities markets are weak-form efficient require looking at patterns of prices. One approach is to see whether there is any serial correlation in security returns.
An alternative approach to test weak-form efficiency is to examine specific trading rules that attempt to exploit historical trading data.
