The analysis of fluctuations of stock market indexes is one of the favorite topics for econophysics experts. The present study in the framework of quantum mechanics from the non-classical oscillator model is conducted an analysis of stock market fluctuations in Iran. This study has been conducted it’s analysis in different groups in the stock market about six active firms. In general, by calibrating the pattern and taking into account the different energy levels (higher energy indicates more information transparency), the results point to the fact that by increasing the level of information in the companies surveyed, it can lead to faster price adjustments and a lowering of the proposed bid and sale price. In other words, with the increase in the energy level, which indicates a decrease in information asymmetry, we can expect that the speed of the attract of news in the market will be slowly and so Transactions and liquidity in stock market increase.

Inferring and inducing among the relations for many of the phenomenas is common in most of sciences. Accordingly, econophysics experts are trying to fill the gap between microeconomics and macroeconomics to explain complex financial systems, using the statistical physics tools. Using a dynamic econometric model, the impact of exchange and gold markets shocks on the stock market is studied. The results show the more significant contribution of the foreign exchange market shocks than the gold market shocks on the fluctuations of stock market. Furthermore, this study forms an assumptive portfolio consisting of three assets including stock, exchange and gold and use random portfolio theory to analyze the risks and uncertainty. The level of uncertainty and risk is studied by using the characteristics of the Castaing, Gagne & Hopfinger distribution functions. The results indicate a high level of uncertainty and risk in the macroeconomic assets portfolio. In other words, the occurrence of financial crises in these markets is expected.
