Let $\, \overline {\! M}$ be a compact Riemannian manifold with sectional curvature $K_{\, \overline {\! M}}$ satisfying $1/5 K_{\, \overline {\! M}}\le 1$ (resp. $2\le K_{\, \overline {\! M}}10$), which can be isometrically immersed as a hypersurface in the Euclidean space (resp. the unit Euclidean sphere). Then there exist no stable compact minimal submanifolds in $\, \overline {\! M}$. This extends Shen and Xu's result for ${1\over 4}$-pinched Riemannian manifolds and also suggests a modified version of the well-known Lawson–Simons conjecture.
