I introduce a model to estimate the risk-neutral density. Current estimation techniques use a single mathematical model to interpolate option prices on two option dimensions: strike price and time-to maturity (TTM). I propose to use B-splines with at-the-money knots for the strike price interpolation and a function that depends on the option expiration horizon for the TTM interpolation. The results of this “hybrid” methodology are significantly better than other risk-neutral density extrapolation methods applied to the Recovery Theorem.
