Investment fund managers have been trying to provide more attractiveness for investors by earning higher yields and generating liquidity. The investment rate of return of a mutual fund is obtained from the difference between the issuance and redemption of Net Asset Values (NAVs) per investment unit. However, the Exchange Traded Funds'(ETFs') yield should be calculated differently, and investors must consider the changes in market prices (Not only the NAVs), which are not usually announced through the Ads, so they disregard the investors. Investment fund managers believe that the attractiveness of the rate of return, even to a small extent, leads to over-welcoming of the investors and a faster growth of the funds' size. According to the information available in recent years, investors have shown more interest in fixed-income investment funds, and the growth of ETFs has been significant compared to the growth of total funds, so it can be assumed that investors are more interested in ETFs. Thus, in this research, we will identify factors affecting the development of ETFs, especially fixed-income ones. To fulfill our purpose, we examined all active fixed-income investment funds that are traded in the Tehran Stock Exchange and the Iran Farabourse from March 2021 to September 2023, including 25 ETFs. We analyzed our panel data through ordinary least squares. Analyzing the effective rate of returns of 25 Fixed Income ETFs, which have been active from March 2021 to September 2023, our results showed that ETFs development is significantly related to the fund size, daily price volatility, and liquidity. Despite our expectations, rate of return, fund age, and price adjustment do not have a significant effect on the development of investment funds. The result showed that a higher rate of return did not have a significant effect on the attractiveness and acceptance of investors, but the liquidity of investment units positively affects the development of fixed-income ETFs. We also found that the daily volatility of the final price inversely impacted the fund's size. This is consistent with investors' low risk-taking spirit in fixed-income funds and emphasizes their preference to avoid liquidity risk and price volatility risk.

Several studies in the field of capital markets indicate that changes in macroeconomic parameters, including crude oil price changes in many cases, have significant effects on capital market indexes. The present study seeks to investigate the effect of crude oil price changes on the indexes of Tehran Stock Exchange and Saudi Stock Exchange also known as The Tadawul Exchange using the two-factor capital asset pricing model with samples gathered from years 2016-2022 from both markets. The results of the study show that, both markets are relatively sensitive to the oil price index and despite severe economic sanctions imposed on Iran, Its capital market, having more significantly oil-related indexes, is still more oil-dependent than that of Saudi Arabia. The results also suggest the asymmetric relation with oil price movements in both countries due to their oil-exporting nature where both markets are more sensitive to negative oil price movements rather than its positive ones. Also, it is concluded that due to the diversity of industries in Tehran Stock Exchange, the economic sanctions imposed on Iran have a more directed impact on its capital market rather than affecting it through a mediator parameter such as oil price movements.
