Abstract: The objective of this work is to determine whether it is possible to forecast, with acceptable accuracy, buying or selling recommendations for stock market shares by creating and training neural network models. Generally, financial market oscillations within a predetermined interval do not depend on a single previous state, but rather it is the accumulation of previous movements that allows estimating future changes. Considering this fact, this study focuses on analyzing Recurrent Neural Networks (RNN) and their Long Short-Term Memory (LSTM) variant. Both algorithms have the ability to memorize previous states as they pass through the neural network and, therefore, are potentially suitable for this task. The development of this project has been based on the creation of multiple RNN and LSTM models and their training using a predefined set of parameters. Three datasets with real stock market data have been used, and the sentiment analysis of financial news has been included using the FinBERT model. The result obtained in each model has provided a curve whose analysis has allowed extracting the points where a relevant oscillation in the stock price has occurred and, consequently, predicting a possible buy or sell order. The conclusion of this study is that it is not possible to reliably predict market trends. There has been no consistency in the results obtained from the three analyzed stocks.
