TY - GEN A1 - Bovier, Anton A1 - ChernĂ˝, JirĂ­ A1 - Hryniv, Ostap T1 - The opinion Game: Stock price evolution from microscopic market modelling N2 - We propose a class of Markovian agent based models for the time evolution of a share price in an interactive market. The models rely on a microscopic description of a market of buyers and sellers who change their opinion about the stock value in a stochastic way. The actual price is determined in realistic way by matching (clearing) offers until no further transactions can be performed. Some analytic results for a non-interacting model are presented. We also propose basic interaction mechanisms and show in simulations that these already reproduce certain particular features of prices in real stock markets.
