(eng): We present a novel approach towards the financial Ising model. Most studies utilize the model to find settings which generate closely mimicking the financial stylized facts such a fat tails, volatility clustering and persistence, and others. Working with the Ising model, we are able to present nicely interpretable results as the model is based on only two parameters. We show that in fact market frictions (to a certain level) and herding behavior of the market participants do not go against market efficiency but what is more, they are needed for the markets to be efficient.
