Investment decisions are examined based on financial concepts that are based on the efficient market hypothesis. Considering the confirmation of the complete inefficiency of Iran's capital market, there is an expectation of obtaining more returns. In this research, we seek to introduce investment portfolios based on the momentum investment strategy (which has been confirmed in various studies) and its combination with other factors affecting the company's value and profitability. Based on this, 119 companies were investigated in the period of 1388 to 1400 in three short-term periods of three and six months and medium-term of one year. According to the findings, the average returns obtained from the formation of different combined portfolios are positive in all periods and the returns of the combined portfolios are higher than the single-criteria portfolios. The investment strategy based on the asset growth rate and momentum in the short-term periods of three and six months and the medium-term of one year has the highest average return, then the strategy based on over-leverage and under-leverage and momentum and finally the strategy based on leverage

Business units are looking for new ways to improve their financial performance and reduce their risk level while financing. Considering previous studies focusing on the role of working capital efficiency on companies finance, we aim to examine the relationship between working capital efficiency and deviation from the optimal level of capital structure.

In this research, two main hypotheses are proposed; firstly, to examine the previously mentioned relationship, and secondly, to measure the difference between the efficiency of working capital and the capital structure in terms of over-leveraged and under-leveraged companies. The data sample is restricted to 179 Firms listed in Tehran Stock Exchange during 2006-2017.

The results demonstrate that with increasing working capital efficiency, the amount of capital structure deviation from the optimal level can be reduced. In addition, the relationship between the efficiency of working capital and the deviation from the optimal level of capital structure in over-leveraged firms is significantly higher than under-leveraged firms.

Information asymmetry and conflicts of interest between management and shareholders leads to the phenomenon of adverse selection. Adverse selection means choosing the wrong investment choices by investors that leads to non-optimal allocation of capital market resources. In this condition, firms cannot easily finance their investment projects. This object leads the firms’ capital structures to a non-optimized mode. One way to avoid this problem is to increase the accruals quality and disclosure quality because this decreases the information asymmetry. This research investigates the effect of accruals quality and disclosure quality on deviation form the optimal capital structure in 123 firms listed in Tehran Stock Exchange during 2003-2014. The research results show that incearse in accruals quality and disclosure quality decrease the deviation from the optimal capital structure. In addition, the research findings indicate that the effect of accruals quality on deviation from the optimal capital structure in over-leveraged firms is significantly stronger than that in under-leveraged firms.
