As one of the developing countries, Turkey strives to meet the need for resources to increase its economic growth. In order to meet this capital need, the Turkish stock exchange was established in 1985. While stock exchanges enable companies to raise funds through public offerings, they also enable investors to earn dividends and trading income. An increase in the number of investors means more resources for the economy. After reaching a certain level in the 2000s, the number of investors in Turkey has fluctuated within a certain fixed corridor for a long time. However, in the continuation of some macroeconomic policies implemented since 2018, there has been a significant increase in the number of investors. While the desired results could not be obtained from the policies implemented to direct investors to the stock market in previous years, current policies have had an effect beyond what was desired. In order to ensure sustainable investor participation in the stock market, analysis of the factors that lead investors to make decisions is needed. For this reason, this study aims to observe the reactions of investors to participate in the stock market in line with the macro-economic, political and social events experienced over the years. The data of the study were obtained from Turkish financial institutions. The findings of the study show that investors tend to invest in stocks besides housing, automobiles, gold and foreign currency to protect their wealth, especially in periods when negative real interest rates are applied. However, it does not seem possible that the negative real interest rate policy will ensure sustainable investor participation in the stock market as a single method. Therefore, there is a need for policies that will attract investors to this market continuously.
