Various deep learning techniques have recently been developed in many fields due to the rapid advancement of technology and computing power. These widely applied finance for stock market prediction, portfolio optimization, risk management, trading strategies. Forecasting indices with noisy data is a complex challenging task, but it plays an important role appropriate timing buying or selling stocks, which one most popular valuable areas finance. In this work, we propose novel hybrid models forecasting one-time-step multi-time-step close prices DAX, DOW, S&P500 by utilizing recurrent neural network (RNN)–based models; convolutional network-long short-term memory (CNN-LSTM), gated unit (GRU)-CNN, ensemble models. We averaging high low as feature. The experimental results confirmed that our outperformed traditional machine-learning 48.1% 40.7% cases terms mean squared error (MSE) absolute (MAE), respectively, case 81.5% MSE MAE forecasting.

Stock Market Prediction With Transductive Long Short-Term Memory and Social Media Sentiment Analysis

IEEE Access, Год журнала: 2024, Номер 12, С. 87110 - 87130

Опубликована: Янв. 1, 2024

In an era dominated by digital communication, the vast amounts of data generated from social media and financial markets present unique opportunities challenges for forecasting stock market prices. This paper proposes innovative approach that harnesses power sentiment analysis combined with to predict prices, directly addressing critical in this domain. A major challenge is uneven distribution across different categories. Traditional models struggle accurately identify fewer common sentiments (minority class) due overwhelming presence more (majority class). To tackle this, we introduce Off-policy Proximal Policy Optimization (PPO) algorithm, specifically designed handle class imbalance adjusting reward mechanism training phase, thus favoring correct classification minority instances. Another effectively integrating temporal dynamics prices results. Our solution implementing a Transductive Long Short-Term Memory (TLSTM) model incorporates findings historical data. excels at recognizing patterns gives precedence points are temporally closer prediction point, enhancing accuracy. Ablation studies confirm effectiveness PPO TLSTM components on overall performance. The proposed advances field analytics providing nuanced understanding but also offers actionable insights investors policymakers seeking navigate complexities greater precision confidence.

Data vs. information: Using clustering techniques to enhance stock returns forecasting

International Review of Financial Analysis, Год журнала: 2023, Номер 88, С. 102657 - 102657

Опубликована: Апрель 23, 2023

This paper explores the use of clustering models stocks to improve both (a) prediction stock prices and (b) returns trading algorithms. We cluster using k-means several alternative distance metrics, as features quarterly financial ratios, daily returns. Then, for each cluster, we train ARIMA LSTM forecasting predict price in cluster. Finally, employ clustering-empowered analyze different obtain three key results: (i) outperform benchmark models, obtaining positive investment scenarios; (ii) is improved by additional information provided methods, therefore selecting relevant data an important preprocessing task process; (iii) from whole sample deteriorates ability models. These results have been validated 240 companies Russell 3000 index spanning 2017 2022, training testing with subperiods.

Artificial Intelligence Based Hybrid Models for Prediction of Stock Prices

Опубликована: Март 3, 2023

Stock price forecasting has recently become an important practical component of the economic arena. An intriguing task, stock is regarded to be related volatility and noise market activity. To address these issues accurately predict prices, this paper proposes a hybrid framework based on learning model such as stacked Long Short Term Memory (LSTM) Convolutional network. Experiments with several possible outcomes are run assess proposed using data set. The was trained ADANI from last roughly fourteen years LSTM network evaluated assessment criteria Root Mean Square Error (RMSE). proven competitive against other models in prediction various scenarios.
