The hadronic tensor molecule M=J/ψJ/ψ is investigated in the framework of QCD sum rule method. We evaluate its mass and current coupling using the two-point SR approach. Our result m=(6290 ± 50)~ MeV for the mass of M indicates that it can decay to a pair of mesons J/ψJ/ψ. Apart from this dominant channel there are subdominant modes of the molecule M generated due to annihilation of constituent cc quarks to pairs of light quarks qq and ss. This mechanism launches processes M → D(s)(∗ )+D(s)(∗ )-, DD1(2420), DsDs1(2460) and D(s)(∗ )0D(s)(∗ )0. The decays of M are explored by applying technical tools of the three-point sum rule approach which is necessary to estimate strong couplings at M-meson-meson vertices. Comparing the mass m of the molecule M and its decay width Γ[M]=(149 ± 21)~ MeV with available experimental data, we discuss the molecule M as a possible candidate to the tensor resonance X(6200).
