In a recent Letter [PRL 113, 120404 (2014)] Ferrie and Combes claimed to show "that weak values are not inherently quantum, but rather a purely statistical feature of pre- and post-selection with disturbance." In this Comment I will show that this claim is not valid. It follows from Ferrie and Combes misunderstanding of the concept of weak value.

Anomalous values, Fisher information, and contextuality, in generalized quantum measurements

In qubit postselected measurements, anomalous values, enhanced Fisher information, and contextuality are not equivalent outside the strict weak-value regime.
