Available in PDF, EPUB and Kindle. Book excerpt: This work creates a new Deep Q-learning model with augmented sentiment analysis and stock trend labelling (DQS model). It incorporates stock market trend label and sentiment analysis score label as input features to improve model accuracy and performance. The first part of this work proves that machine learning models can predict stock price trends instead of just accurate stock prices. It studies the performance difference between neural networks and other maching learning algorithm performance for stock price trend prediction. It shows that neural networks can accurately predict stock trends when stock price data are preprocessed and transformed into category data. Subsequently, this work utilizes Valence Aware Dictionary for Sentiment Reasoning (VADER) to predict the sentiment score of new titles. A correlation study shows that there is a strong correlation between stock price and and market daily sentiment. Lastly, a new neural network customized for this application has been utilized in the DQS model to map state features to action for trading decision making.

Download or read book Stock Market Prediction Through Sentiment Analysis of Social Media and Financial Stock Data Using Machine Learning written by Mohammad Al Ridhawi and published by . This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Given the volatility of the stock market and the multitude of financial variables at play, forecasting the value of stocks can be a challenging task. Nonetheless, such prediction task presents a fascinating problem to solve using machine learning. The stock market can be affected by news events, social media posts, political changes, investor emotions, and the general economy among other factors. Predicting the stock value of a company by simply using financial stock data of its price may be insufficient to give an accurate prediction. Investors often openly express their attitudes towards various stocks on social medial platforms. Hence, combining sentiment analysis from social media and the financial stock value of a company may yield more accurate predictions. This thesis proposes a method to predict the stock market using sentiment analysis and financial stock data. To estimate the sentiment in social media posts, we use an ensemble-based model that leverages Multi-Layer Perceptron (MLP), Long Short-Term Memory (LSTM), and Convolutional Neural Network (CNN) models. We use an LSTM model for the financial stock prediction. The models are trained on the AAPL, CSCO, IBM, and MSFT stocks, utilizing a combination of the financial stock data and sentiment extracted from social media posts on Twitter between the years 2015-2019. Our experimental results show that the combination of the financial and sentiment information can improve the stock market prediction performance. The proposed solution has achieved a prediction performance of 74.3%.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Because of its importance in the economy, the stock market prediction has always been a hot topic. In order to avoid investment risks, there is always an urgent need to uncover the stock market's future behavior. Before making a trading decision to buy or sell a stock, stock traders must be able to predict its behavior trends. The more accurately they predict the behavior of a stock, the more profit they make. However, determining stock market trends is a difficult task due to factors such as industry performance, company news, company performance, investor sentiment, economic variables, and, in particular, social media sentiment. As a result, reading the market's stock sentiment has become critical to making a sound investment. The purpose of this study is to examine previously used Machine Learning and Deep Learning models, explore new models, optimize them with better techniques, and compare them to determine which models are the most effective at predicting stock market sentiment. The SVM classifier performed best in my experiments, with a classification accuracy score of 91%, followed by the Passive-Aggressive classifier and the LSTM model, both of which achieved 90% accuracy, and then comes the Naive Bayes model, which achieved 89% accuracy.

This book was released on 2018-09-18 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: Project Report from the year 2018 in the subject Computer Science - Technical Computer Science, , course: Computer Science, language: English, abstract: Modeling and Forecasting of the financial market have been an attractive topic to scholars and researchers from various academic fields. The financial market is an abstract concept where financial commodities such as stocks, bonds, and precious metals transactions happen between buyers and sellers. In the present scenario of the financial market world, especially in the stock market, forecasting the trend or the price of stocks using machine learning techniques and artificial neural networks are the most attractive issue to be investigated. As Giles explained, financial forecasting is an instance of signal processing problem which is difficult because of high noise, small sample size, non-stationary, and non-linearity. The noisy characteristics mean the incomplete information gap between past stock trading price and volume with a future price. The stock market is sensitive with the political and macroeconomic environment. However, these two kinds of information are too complex and unstable to gather. The above information that cannot be included in features are considered as noise. The sample size of financial data is determined by real-world transaction records. On one hand, a larger sample size refers a longer period of transaction records; on the other hand, large sample size increases the uncertainty of financial environment during the 2 sample period. In this project, we use stock data instead of daily data in order to reduce the probability of uncertain noise, and relatively increase the sample size within a certain period of time. By non-stationarity, one means that the distribution of stock data is various during time changing. Non-linearity implies that feature correlation of different individual stocks is various. Efficient Market Hypothesis was developed by Burton G. Malkiel in 1991.

Download or read book Sentiment and Technical Analyses for Stock Market Forecasting Through Machine Learning written by Joshua Licudo and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The proliferation of social media combined with advancements in machine learning allows for researchers to easily capture a userbase's opinions on a given topic, and stock market sentiment is no exception to this. Although discussions on social media are typically informal and written by users who are not necessarily market experts, public platforms are still a reflection of public opinion. Acting contrary to the public, in line with the well-known adage "be greedy when others are fearful, and fearful when others are greedy," is nonetheless a proven strategy. This project explores existing tools and libraries for both sentiment and time series analyses, integrating both to apply a contrarian approach to stock trading. At first, a general approach analyzing stocks measured by the Dow Jones Industrial Average and discussions pertaining to them on Reddit was taken, but numerous flaws with this made the project pivot over to margin trading with popular stocks discussed on the subreddit r/wallstreetbets, especially given Reddit's recent notoriety after the 2021 GameStop short squeeze. Since tens of thousands of posts are submitted to r/wallstreetbets every day, optimal performance of all project components became a critical metric for practical viability. Two simulations were constructed using one day of one-minute interval data and five days of five-minute interval data to capture performance benchmarks for a sentiment analysis model using VADER, and two time series analysis models, one using ARIMA/GARCH and the other using LSTM, were compared for performance and accuracy. While the best overall results were observed using the ARIMA/GARCH model, poor performance scaling was observed in the sentiment analyzer, making it infeasible to execute simulations across timeframes longer than five days. Future work should focus on exploration of additional sentiment and time series analysis models and optimization of the sentiment analyzer.

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stock market trends are of great interest to investors and corporations worldwide. The global financial system is intricately interconnected with the stock market, playing a central role in driving economic activity. In today's interconnected world, trading stocks has become a popular and accessible means for individuals and entities to generate income. Numerous academic researchers have explored the use of Artificial Intelligence (AI) for stock prediction and have claimed that their models can accurately forecast stock performance. The issue is that many of these studies rely on a single data source, namely, daily stock data and cannot predict future stock prices, more than 1 or 2 days, with a large degree of success. Additionally, the single data source may be influenced by a multitude of economic factors as well as public sentiment, which is the most significant. In this research paper, several of these AI models are tested to evaluate their claims regarding stock prediction capabilities. Based on our experiments utilizing AI models and the results gathered, it was concluded that it was not possible to predict future stock prices using one method alone. Therefore, in order to provide a greater accuracy in predicting future stocks, the use of an ensemble approach was proposed. While many researchers build their ensemble models by combining various Artificial Neural Network models with sentiment analysis. We have suggested a different approach using other kinds of AI models, along with enhancements to traditional sentiment analysis techniques.

Available in PDF, EPUB and Kindle. Book excerpt: Stock price forecasting is a popular and important topic in financial and academic studies. Share market is an volatile place for predicting since there are no significant rules to estimate or predict the price of a share in the share market. Many methods like technical analysis, fundamental analysis, time series analysis and statistical analysis etc. are used to predict the price in tie share market but none of these methods are proved as a consistently acceptable prediction tool. In this paper, we implemented a Random Forest approach to predict stock market prices. Random Forests are very effectively implemented in forecasting stock prices, returns, and stock modeling. We outline the design of the Random Forest with its salient features and customizable parameters. We focus on a certain group of parameters with a relatively significant impact on the share price of a company. With the help of sentiment analysis, we found the polarity score of the new article and that helped in forecasting accurate result. Although share market can never be predicted with hundred per-cent accuracy due to its vague domain, this paper aims at proving the efficiency of Random forest for forecasting the stock prices.

Download or read book A Robust Predictive Model for Stock Price Prediction Using Deep Learning and Natural Language Processing written by Sidra Mehtab and published by . This book was released on 2020 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prediction of future movement of stock prices has been a subject matter of many research work. There is a gamut of literature of technical analysis of stock prices where the objective is to identify patterns in stock price movements and derive profit from it. Improving the prediction accuracy remains the single most challenge in this area of research. We propose a hybrid approach for stock price movement prediction using machine learning, deep learning, and natural language processing. We select the NIFTY 50 index values of the National Stock Exchange (NSE) of India, and collect its daily price movement over a period of three years (2015-2017). Based on the data of 2015-2017, we build various predictive models using machine learning, and then use those models to predict the closing value of NIFTY 50 for the period January 2018 till June 2019 with a prediction horizon of one week. For predicting the price movement patterns, we use a number of classification techniques, while for predicting the actual closing price of the stock, various regression models have been used. We also build a Long and Short-Term Memory (LSTM)-based deep learning network for predicting the closing price of the stocks and compare the prediction accuracies of the machine learning models with the LSTM model. We further augment the predictive model by integrating a sentiment analysis module on Twitter data to correlate the public sentiment of stock prices with the market sentiment. This has been done using Twitter sentiment and previous week closing values to predict stock price movement for the next week. We tested our proposed scheme using a cross validation method based on Self Organizing Fuzzy Neural Networks (SOFNN) and found extremely interesting results.

Download or read book Recent Advances in Stock Market Prediction Using Text Mining written by Faten Subhi Alzazah and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Market prediction offers great profit avenues and is a fundamental stimulus for most researchers in this area. To predict the market, most researchers use either technical or fundamental analysis. Technical analysis focuses on analyzing the direction of prices to predict future prices, while fundamental analysis depends on analyzing unstructured textual information like financial news and earning reports. More and more valuable market information has now become publicly available online. This draws a picture of the significance of text mining strategies to extract significant information to analyze market behavior. While many papers reviewed the prediction techniques based on technical analysis methods, the papers that concentrate on the use of text mining methods were scarce. In contrast to the other current review articles that concentrate on discussing many methods used for forecasting the stock market, this study aims to compare many machine learning (ML) and deep learning (DL) methods used for sentiment analysis to find which method could be more effective in prediction and for which types and amount of data. The study also clarifies the recent research findings and its potential future directions by giving a detailed analysis of the textual data processing and future research opportunity for each reviewed study.
