“…Future price predictions of stocks can also be made by methods such as artificial neural networks (Khan etc., 2011). In addition, there are many studies showings that the values of stocks offered for sale during the global crisis decreased to lower levels than expected (Boudriga and Ghachem, 2016).

One of the main investment instruments that attract foreign and domestic investors is the stocks of companies. The Istanbul Stock Exchange, which has been serving more than 300 companies with a volume of billions of dollars since 1985, offers various opportunities to international investors. Of course, investors have to apply to many analyzes of companies and companies in order to evaluate these opportunities correctly and to make a profit. Therefore, it is of great importance for millions of investors around the world that firm and market data are highly transparent, consistent and predictable. Because otherwise, markets that cannot show stability in developing countries cause the market values of the company to rise and fall excessively with the opportunities and crises that constantly occur. This situation leads to unnoticeable manipulations in firm and market values and investors to be mistaken due to the inability to analyze them correctly. The purpose of this research is to estimate the market values of 2019 Borsa Istanbul firms by using Artificial Neural Networks (ANN) method with the data of Forbes 2000 companies in 2019. As a result of the analysis, it was revealed that the companies in Borsa Istanbul have higher or lower market values than they should be, and the results are also supported by the comparisons of ratio analysis. IntroductionEquity markets are a public market in which company shares are traded at an agreed price and offer investors the opportunity to share the company's profits based on the amount of ownership (Barnes, 2016). Investors need to analyze the market and the company correctly in order to predict these ups and downs. However, manipulations that may arise with high competition can cause competition and mislead investors (Aggarwal and Wu, 2003). Future price predictions of stocks can also be made by methods such as artificial neural networks (Khan etc., 2011). In addition, there are many studies showings that the values of stocks offered for sale during the global crisis decreased to lower levels than expected (Boudriga and Ghachem, 2016). In this risky conjuncture, one of the most concrete methods of providing information about the business performance and economic variables of companies is ratio analysis (Drake and Fabozzi, 2012). However, for these analyzes to yield clear results, company data should be compared with companies in global markets and unreliable markets or companies should be distinguished from others. Ratio analysis is one of the main indicators by which investors can predict the financial performance of companies they want to buy stocks (Nikolai etc. 2009). In these analyzes, variables such as the sales amount, profit, assets and market values of the companies are used.In this research, the estimated market values of Borsa Istanbul companies, which are a platform where international investors can evaluate their money, were reached and compared with the real market values. Based on the optimum sales, profit, assets and market values of the best Forbes 2000 compan...
