Abstract. Expressing option prices as Black-Scholes implied volatilities reveals features of the underlying probability distribution. We investigate a manifestation of this idea in a near-Gaussian asymptotic regime, where we rigorously relate the shape of the implied volatility skew to the cumulants of the underlying distribution.
