One of the possible attractive investment options is the purchase of securities on the stock market. The investor strives to make a portfolio out of all possible investment instruments available on the exchange, which will be optimal according to a certain criterion. Before analyzing the data, it is necessary to check their stationarity. This is due to the fact that the non-stationary model is unable to accurately reflect the patterns in the data structure, which means that the results obtained may be distorted.
