The purpose of this study was to investigate the effect of firm size and financial leverage on the relationship between working capital financing and profitability in companies listed on the Tehran Stock Exchange using panel data during the period 2013-18, through the generalized torque method. (GMM). The variables of firm size and financial leverage are moderators whose effect on the relationship between working capital financing as an independent variable and profitability as a dependent variable is studied. The results of the study showed that there is an inverse U-shaped relationship between working capital financing and profitability. Also, the inverse U-shaped relationship between working capital financing and profitability is weaker in firms with small firms than in large firms. Also, the inverse U-shaped relationship between working capital financing and profitability in companies with high financial leverage is weaker than other companies. In other words, the relationship between profitability and financing through working capital is adjusted by the financial leverage and size, and this adjustment goes to a certain extent and is reversed from then on, which is the breaking point. The relation series is U-shaped.

First، through runs test، skeweness، kurtosis، and duration dependence test the incidence of bubbles in Tehran Stock Exchange during the years 2004 to 2009 at 95% confidence level were studied. Then all companies that have had severe price volatility have been selected as examples. Totally، a number of 246 companies qualified for the study were selected. And then، by price bubble tests، all companies were divided in two groups، with and without bubbles. To predict bubbles، based on theoretical frameworks، we used indigenous variables such as size of company، P/E ratio، information transparency، stockholder combination، and liquidity rate as independent variables. Then، login binary regression and artificial neural networks (ANN) were used to model and predict bubbles.

The Tehran exchange after reopening in 1368 ,has been undergone fluctuations during its activities that these fluctuations often were market inherent and indicate what it has happened in the markets.
