The leptokurtic distributions of price return can be reproduced by our quantum model with the introduction of mixed-state and multi-potential. Stock market forces can be modeled with a quantum harmonic oscillator Traditionally, a quantum harmonic oscillator model is used to describe the tiny vibrations in a diatomic molecule, but the description is also universal in the sense that it can be extended to … We propose a quantum harmonic oscillator as a model for the market force which draws a stock return from short-run fluctuations to the long-run equilibrium. The MarketWatch News Department was not involved in the creation of this content. We propose a quantum harmonic oscillator as a model for the market force which draws a stock return from short-run fluctuations to the long-run equilibrium. A financially interpretable quantum model is proposed to study the probability distributions of the stock price return. Instead of a harmonic oscillator in previous studies, a quantum anharmonic oscillator is applied to the stock in liquid market. Then the probability distributions of price return can be computed from the wave functions that evolve according to Schrodinger equation. The stochastic equation governing our model is transformed into a Schrödinger equation, … Sep 25, 2020 (The Expresswire) -- Global “Harmonic Oscillator Market” forecast report … The dynamics of a quantum particle is considered an analog of the motion of stock price.
