Bootstrapping is an effective simulation approach that naturally incorporates correlations between asset returns and non-normality of asset returns, but does not generally capture autocorrelation of asset returns. 请问后面这句but does not generally capture autocorrelation of asset returns如何理解?bootstrapping不是会出现数据之间的相关性吗?

同学你好,是会有自相关性,这句话的意思是他是没有体现出这种关系,所以这个是他的一个缺点。
