The most sensitive domain is the stock market. People’s sentiments can change the market trend overnight. However, a large number of factors affect the movement of the stock market, and one of these is traders’ sentiment while driving the market.
In the present era, the finance sector is inevitable to invest in the stock market because high stock market value is a parameter of high economies. The stock market’s volatile nature gives equal chances for earning money and losing money. But if the situation can be predicted, then investors can profit or minimize their losses.
Since then, artificial intelligence companies have used sentiment analysis in the stock market to predict the market trend or movement of a particular stock. Social media is one of the best platforms for understanding the sentiments of people trading or investing in the stock market or any other financial instruments traded on various exchanges.
What is Sentiment Analysis, and How Does It Work?
This is the process of analyzing people’s sentiments through different platforms, such as social media and similar websites, on which people can freely express their feelings or opinions about anything they think.
Classification of such sentiments can be done at the phrase, sentence, and document levels. Sentiment analysis uses Natural Language Processing (NLP) to divide the language units into three categories: Negative, Positive, and Neutral.
Facebook, Twitter, and LinkedIn are some of the leading social media networking sites where people express their opinions and feelings about things that reveal their emotions. Here, people also talk about what they think, whether one is a good expert in that field or not.
Social media is accessible through portable devices like smartphones, making it easier for people to post content and spread their views on various topics. News, including fake news or rumors, also spreads there at a very fast pace.
Such news or information affects people all over the world. If the news is related to the stock market, investors will also be affected and decide to buy or sell a stock or vice versa accordingly; therefore, that will positively or negatively impact the price of stock trading on exchanges.
How Sentiments Analysis Work in Stock Prediction?
Well, Sentiment Analysis and the stock market are already well-researched topics. There are already lots of forces behind the movement of the stock market or a particular share of a company. Maybe due to negative sentiment, the stock price goes down, or if there are any positive sentiments, the stock prices may increase.
Since no technique can precisely predict the movement of the stock, many researchers have passed through numerous experiments to obtain better results. However, due to the universal use of social media websites, they can be considered to be very important in predicting stock movement since investors share their opinions and thoughts in media.
An analysis of such social media platforms or microblogging websites using sentiment analysis datasets would give some idea about what people are talking about and what they think about a particular stock. The contents of Social Media, such as posts, tweets, photos, etc., are analyzed by people of different communities, like politicians, marketers, and analysts, to make the right decision while investing in such markets.
Sentiment Analysis and Prediction System Based on Social Media Contents
Social media is very much playing a role in sentiment analysis in the stock market. Even in the last couple of years, the influence of social media sites has become so big that information about major and minor incidences or disasters is obtained through social media sites. Due to the influence of the social ripple effect of social media sites, diverse studies are going on to analyze the content generated online.
The methods and purposes of content analysis on social media are diverse, but there are some commonalities. The most direct and important information is found in texts directly written by users. Since content is created according to the user’s intention at the time of creation, time also becomes an important factor in sentiment analysis through such content.
In today’s world, the internet user’s popularity grows fast, just like emerging technologies, who actively use online review sites, social networks, and personal blogs to express their opinions. It can provide an opportunity to know the positive and negative attitudes about people, organizations, places, events, and ideas.
So, with the aid of natural language processing and machine learning, along with other approaches to working with large text volumes, it is now feasible to start extracting sentiments from social media.
Impact of Social Media on the Stock Market
As we can see in the modern world, people make judgments regarding the world when they stay in society. They show positive and negative attitudes about people, products, places, and events. These attitudes may be termed sentiments.
Sentiment analysis is the study of automated techniques to extract sentiments from written languages. The growth of social media has resulted in an explosion of publicly available UGC moderation services to control such content.
Such data and information could potentially be used to provide real-time insights into people’s feelings. Blogs, online forums, comment sections on media sites, and social networking sites like Facebook and Twitter are all considered social media that capture millions of people’s views or word of mouth.
Thus, communication and the prevalence of real-time opinions from diverse people all over the world are revolutionizing computational linguistics and social network analysis. As time passes, social media is becoming an increasingly influential source of information for anybody, including investors trading in the stock markets.
When a piece of news comes into the market, people start talking about it, and they give their positive or negative opinions, showing their sentiments. Sentiment analysis experts can use such views to predict the movement of the stock market or a particular company’s stock.
In contrast, more people are willing and ready to share the facts of their lives, knowledge, experiences, and thoughts with the whole world over social media channels than ever before.
An example of Twitter used for Sentiment Analysis in Stock Prediction
The task of sentiment analysis is quite field-specific. Tweets are classified into positive, negative, and neutral, given the sentiment present. Out of the total, the number of tweets is examined by humans and annotated as 1 for Positive, 0 for Neutral, and 2 for Negative emotions. For the text classification of nonhuman annotated tweets, a machine learning model is so trained whose features are extracted from the human-annotated tweets.
Such data is fetched from Twitter and other similar platforms and then used as a training data set to train the AI model through sentiment analysis algorithms to predict the price of stocks in different scenarios. Except in extreme or unexpected conditions, most of the time, models based on machine learning or deep learning predict at very high accuracy to help stock market investors earn money.
Conclusion
They engage in activities by reflecting on their opinions and mentioning their observations that happen within society. This way of reflecting society and social platforms for the transmission of their knowledge and emotions forces the organizations to gather maximum information about their companies, products, and to what extent they are popular among the masses and reach decisions to take appropriate action and continue their business transactions effectively.
