In practice, we may be concerned with values of return (or another variable) below some level other than the mean. For example, if our return objective is 12.75 percent annually, we may be concerned particularly with returns below 12.75 percent a year. We can call 12.75 percent the target. The name target semivariance has been given to average squared deviation below a stated target, and target semideviation is its positive square root.
