Using $1310.6\times10^{6}$ $J/\psi$ and $448.1\times10^{6}$ $\psi(3686)$events collected with the BESIII detector, the branching fractions of $J/\psi$and $\psi(3686)$ decays to $\Sigma^{+}\overline{\Sigma}^{-}$ are measured to be$(10.61 \pm 0.04 \pm 0.36) \times 10^{-4}$ and $(2.52 \pm 0.04 \pm 0.09) \times10^{-4}$, respectively. In addition, the ratio of $\mathcal{B}(\psi(3686)\rightarrow \Sigma^{+}\overline{\Sigma}^{-})/\mathcal{B}(J/\psi \rightarrow\Sigma^{+}\overline{\Sigma}^{-})$ is determined to be $(23.8 \pm 1.1)\%$ whichviolates the "$12\%$ rule".
