In this contribution, we continue the investigation of the SRCEN estimator of the extreme-value index γ (or the tail index α = 1∕γ) proposed in McElroy and Politis (J Statist Plan Infer 137:1389–1406, 2007) for γ > 1∕2. We propose a new estimator based on the local maximum. This, in fact, is a modification of the SRCEN estimator to the case γ > 0. We establish the consistency and asymptotic normality of the newly proposed estimator for i.i.d. data. Additionally, a short discussion on the comparison of the estimators is included.
