Computing Skew-Stickiness

Empirically, implied volatility moves proportionally to the implied volatility skew; the constant of proportionality, the skew-stickiness ratio (SSR) is roughly independent of time to expiry.  We express the value of the SSR in terms of diamond trees (related to Bergomi-Guyon spot volatility autocorrelation functionals). We provide a general formula valid for very expirations and plot the SSR for longer expirations.  The empirical behavior of the SSR seems to be inconsistent with (classical or rough) stochastic volatility.
