• We consider properties of the measurement intensity ρ of a random variable for which the probability density function represented by the corresponding Wigner function attains negative values on a part of the domain. We consider a simple economic interpretation of this problem. This model is used to present the applicability of the method to the analysis of the negative probability on markets where there are anomalies in the law of supply and demand (e.g. Giffen’s goods). It turns out that the new conditions to optimize the intensity ρ require a new strategy. We propose a strategy (so-called à rebours strategy) based on the fixed point method and explore its effectiveness. •We discuss the properties of the intensity of profit on markets where there are anomalies in the law of supply and demand.•We use probabilistic interpretation of the supply and demand curves.•We present a method of the analysis of the negative probability on markets.•Fixed-point equation is used to find optimal strategy.
