A sampling distribution is a probability distribution of a sample statistic taken from a greater population. Researchers typically use sample data to estimate the population data, and the sampling distribution explains how the sample mean will vary from sample to sample. The standard error of the mean is the standard deviation of the sampling distribution of the mean.1

In finance, the SEM daily return of an asset measures the accuracy of the sample mean as an estimate of the long-run (persistent) mean daily return of the asset.
