Analytical expressions for the marginal stability boundary for resistive ballooning modes at high beta are obtained in the limits of both large and small global shear. These results confirm the recent numerical finding of Sykes et al. [Plasma Phys. Controlled Fusion 29, 719 (1987)] that resistive ballooning modes are stable throughout most of the regime corresponding to ideal ballooning ``second stability'' in high-beta tokamaks.
