基础班视频讲解中，Capital market expectation，limitation of historical estimates中说到高频数据会导致asynchronicity的问题，从而低估correlation。我能理解correlation会发生偏离，但课件中写道：asynchronicity distorts … and induces relationships that might not exist if the data were measured synchronously. 意思是asynchronicity会显示在synchronously下本应无关的数据有关系，感觉是高估correlation。希望老师解答下，谢谢。
