In stock trading, all investors want to make maximum profit. The profit is realized by increasing the share price and paying dividends. The assumption of making a profit is the analysis of the price and value of the share, the company's operations and the financial market. This specialist graduate professional paper analyzes stocks and presents tools that can be used in easier selection of stocks in which to invest in order to reduce investment risk. One of the largest Croatian companies Ad Plastik d.d. is analyzed. and its stock. Ad Plastik d.d. is an example of a company that was privatized which subsequently continued its growth and development. For years, the company has been increasing the production of plastic car parts for most of the world's car manufacturers, raising quality and generating revenue growth. Two methods are used to analyze business and stock prices: fundamental and technical analysis. Fundamental analysis is done on the basis of financial statements that are made public. Technical analysis uses historical data on share price and sales volume to try to predict future stock price movements using a series of statistical methods. The analysis considers the time period from 2017 to 2020. The most important patterns and indicators needed to assess the movement of the share price trend are presented. It was determined how much the price of the observed share was underestimated in the financial market, which means that price growth should be expected. Given that there is still a crisis and uncertainty over the global pandemic, it is understandable that investors are approaching investment carefully; they are waiting for new information every day and are not sure about short-term investments. However, the long-term technical analysis shows that the market price of the stock will continue to grow and that this is a good long-term investment.
