N2 - We derive sum rules involving moments of the U(1) charge in the Ramond sector of N = 2 superconformal field theories. These charge sum rules are obtained by analyzing the modular properties of the elliptic genus. The lowest order sum rule, 〈Q2〉 = 1 12 c ̂, pertains to the average of the charge squared over the Ramond ground ring. The higher sum rules contain information on the null-state structure of the underlying chiral algebra.
