Going forward, let us head to the introduction of market sentiment and sentiment analysis in detail. There are two important terms here: market sentiment and sentiment analysis. In simple words, sentiment analysis is driven by market sentiment.

But what does each term mean?  Let us discuss below.


What is market sentiment?

The market sentiment reflects the collective psychology and view of market participants, which can influence their buying and selling decisions.

Various factors, including economic indicators, corporate earnings reports, geopolitical events, central bank policies, news sentiment, and social media sentiment influence market sentiment. It can significantly impact market dynamics, leading to price volatility, trends, and market cycles.

Types of Market Sentiments

Market sentiment can be categorised into three main types:

Bullish Sentiment

Bullish sentiment occurs when the majority of market participants have a positive outlook on the market or a specific asset. They expect prices to rise and may be more inclined to buy and hold assets in anticipation of future gains. Positive economic news, favourable market conditions, and strong investor confidence can contribute to bullish sentiment.

Bearish Sentiment

Bearish sentiment, on the other hand, represents a negative outlook on the market or a specific asset. Market participants with bearish sentiment expect prices to decline and may take actions such as selling assets or short-selling in anticipation of future losses. Negative economic news, geopolitical uncertainties, and pessimistic investor sentiment can contribute to bearish sentiment.

Neutral Sentiment

Neutral sentiment reflects a more balanced or indifferent attitude towards the market. Market participants with neutral sentiments may neither strongly believe in an upward nor downward price movement. They may adopt a wait-and-see approach, observing market developments before making any significant trading decisions.

It's important to note that market sentiment is subjective and can change rapidly based on new information or events. Therefore, combining market sentiment analysis with other fundamental and technical analyses is crucial to form a comprehensive view of the market and make well-informed trading decisions.


What is sentiment analysis?

Sentiment analysis is the process of analysing and interpreting the emotions, opinions, and attitudes expressed in text data. It involves using natural language processing (Learn the natural language processing python course from Quantra) and machine learning techniques to determine the sentiment behind the text, whether positive, negative, or neutral.

Sentiments

The goal of sentiment analysis is to understand the subjective information conveyed in text and extract meaningful insights from it. It has applications in various domains, including:

  • social media analysis,
  • customer feedback analysis,
  • brand reputation management,
  • market research, and
  • financial trading.

Sentiment analysis provides valuable insights into public opinion, customer sentiment, or market sentiment. It helps businesses to:

  • understand customer feedback,
  • identify trends,
  • measure brand reputation, and
  • make data-driven decisions.

In financial trading, sentiment analysis can be used to:

  • gauge market sentiment,
  • identify potential risks or opportunities, and
  • inform trading strategies.

It's important to note that sentiment analysis is not perfect and can be challenging due to the complexity of language, sarcasm, irony, and context. Therefore, it's crucial to continuously refine and improve the sentiment analysis models based on feedback and domain-specific requirements.


Fundamentals of sentiment analysis

The fundamentals of sentiment analysis involve understanding the key concepts and techniques used in analysing and interpreting sentiment in text data. Here are the fundamental aspects of sentiment analysis:

Text preprocessing

Preprocessing text data is an essential step in sentiment analysis. It involves cleaning the text by removing noise, such as special characters, punctuation, and HTML tags. Additionally, converting the text to lowercase, removing stopwords (common words with little semantic meaning), and performing tokenisation (splitting text into individual words or tokens) are commonly applied preprocessing techniques.

Sentiment lexicons

Sentiment lexicons are dictionaries or databases that associate words with sentiment scores or labels. They contain a list of words and their corresponding polarity, indicating whether they are positive, negative, or neutral. Lexicons serve as a valuable resource for sentiment analysis, as they help assign sentiment labels to words in the text.

Rule-based approaches

Rule-based approaches rely on predefined linguistic rules to determine the sentiment of a text. These rules can be based on grammatical patterns, syntactic structures, or a combination of word-level and context-based rules. Rule-based approaches are often used in conjunction with sentiment lexicons to classify sentiment.

Machine learning approaches

Machine learning techniques are widely used in sentiment analysis. Supervised learning algorithms, such as Naive Bayes, Support Vector Machines (SVM), and Random Forests, are commonly applied. These algorithms are trained on labelled datasets, where the sentiment of the text is known, and then used to predict the sentiment of unseen text data.

Feature extraction

Feature extraction involves converting the preprocessed text data into numerical features that can be used as input for sentiment analysis models. Common feature extraction techniques include the bag-of-words model, which represents the text as a frequency distribution of individual words or n-grams, and TF-IDF (Term Frequency-Inverse Document Frequency), which weights words based on their importance in a specific document relative to a collection of documents.

Neural Networks and Deep Learning

Deep learning models, particularly neural networks, have shown significant advancements in sentiment analysis. Recurrent Neural Networks (RNN), such as Long Short-Term Memory (LSTM) and Gated Recurrent Unit (GRU), are widely used for sequence modelling and sentiment analysis tasks. These models can capture contextual dependencies and long-term dependencies in text data.

Evaluation metrics

Various evaluation metrics are used to assess the performance of sentiment analysis models. Common metrics include accuracy, precision, recall, and confusion matrix. These metrics help measure the model's ability to classify sentiment and determine its overall effectiveness correctly.

It's important to note that continuous experimentation and refinement are necessary to improve the accuracy and effectiveness of sentiment analysis models.


Role of sentiment analysis in trading

Sentiment analysis plays a significant role in trading by providing valuable insights into market sentiment and helping traders make informed decisions. Here are some key roles of sentiment analysis in trading:

Market sentiment gauging

Sentiment analysis allows traders to gauge the market's overall sentiment or specific assets. By analysing news sentiment, social media sentiment, or other sources of sentiment data, traders can understand the prevailing emotions, opinions, and attitudes of market participants. This information helps them gain a broader perspective on market sentiment and identify potential trends or shifts in sentiment.

Captures sentiment shifts

Sentiment analysis can help identify potential market turning points by capturing sentiment shifts. Sudden changes in sentiment, such as a shift from bullish to bearish or vice versa, can indicate a potential change in market direction. Traders can use sentiment analysis to detect these shifts early and adjust their trading strategies accordingly.

News and event impact assessment

Sentiment analysis can help traders assess the impact of news releases, corporate announcements, economic indicators, and other events on market sentiment. By analysing the sentiment associated with specific news or events, traders can better understand how market participants react and adjust their trading strategies accordingly.

Risk management

Sentiment analysis can assist in risk management by identifying potential risks associated with extreme sentiment levels. If sentiment becomes overly positive or negative, it may indicate a market bubble, irrational exuberance, or excessive pessimism. Traders can use sentiment analysis to monitor sentiment extremes and adjust their risk management strategies accordingly.

Algorithmic trading strategies and Quantitative trading strategies

Sentiment analysis can be integrated into algorithmic trading strategies and quantitative strategies. By incorporating sentiment data as an additional input, traders can develop models that take into account both quantitative factors (such as price and volume) and sentiment-related factors. This can help improve trading strategies and generate alpha.

Event-driven Trading

Sentiment analysis can be particularly valuable in event-driven trading, where traders seek to capitalise on market reactions to specific events. By analysing sentiment surrounding events such as earnings releases, product launches, or regulatory decisions, traders can identify opportunities for quick trades based on sentiment-driven price movements.

Overall, sentiment analysis gives traders a deeper understanding of market sentiment, helps identify potential market trends and turning points, enhances risk management strategies, and can be integrated into algorithmic trading and event-driven trading strategies. By leveraging sentiment analysis, traders can make more informed decisions and potentially gain a competitive edge in the market.


Sentiment indicators

Sentiment trading indicators analyse market participants' sentiment and mood to gain insights into market trends and potential trading opportunities.

Here are some examples of sentiment trading indicators:

Put/Call Ratio

This indicator compares the volume of put options (bearish bets) to call options (bullish bets). A high put/call ratio suggests bearish sentiment, while a low ratio indicates bullish sentiment.

Volatility Index (VIX)

Also known as the "fear index," the volatility index (VIX) measures market volatility based on options prices. A high VIX implies higher market uncertainty and fear, reflecting negative sentiment, while a low VIX indicates complacency and positive sentiment.

Commitment of Traders (COT) Report

The COT report reveals positions held by different trader types in futures markets, such as commercial hedgers, large speculators, and small speculators. Analysing their positioning provides insight into sentiment. For instance, heavy long positions by large speculators might suggest bullish sentiment.

Social Media Sentiment Analysis

By analysing sentiment on social media platforms like Twitter and Reddit, traders can gain insights into the sentiment of retail traders and investors. Monitoring overall sentiment, discussion volume, and specific keywords helps identify sentiment shifts.

News Sentiment Analysis

Examining sentiment in news articles and headlines using sentiment analysis techniques provides insights into market sentiment. Tracking sentiment in financial news helps traders identify sentiment changes.


Sentiment trading strategies

There are several types of sentiment trading strategies that traders can employ to capitalise on market sentiment. Here are some common types of sentiment strategies:

Crowdsources sentiment strategy

Crowdsourced sentiment strategies involve leveraging the collective wisdom and opinions of a large group of individuals to make trading decisions. It harnesses the power of the crowd's insights and sentiment to gain market intelligence and identify potential trading opportunities.

Contrarian strategy

Contrarian sentiment strategies involve taking positions opposite to the prevailing sentiment in the market. When sentiment becomes excessively positive or negative, contrarian traders anticipate a market reversal. They buy when sentiment is extremely negative (anticipating a bounce back) and sell when sentiment is extremely positive (expecting a correction).

Trend-following strategy

Trend following strategies aim to align with the prevailing sentiment and trends in the market. Traders identify sentiment indicators that confirm the existing market trend. They buy when sentiment is positive and in line with an uptrend or sell when sentiment is negative and aligns with a downtrend.

Event-driven strategy

Event-driven sentiment strategies focus on sentiment changes around specific events, such as earnings announcements, product launches, regulatory decisions, or economic data releases. Traders analyse sentiment before and after the event to gauge market reaction. Positive sentiment can lead to long positions, while negative sentiment can trigger short positions.

Options trading strategy

Sentiment analysis can be used in options trading strategies. Traders look for extreme sentiment readings to identify potential overbought or oversold conditions. For example, if sentiment is excessively bearish, options traders may consider selling put options or buying call options to take advantage of a potential market reversal.

News-based strategy

News-based sentiment strategies involve monitoring sentiment in financial news sources. Traders analyse sentiment in news articles, headlines, and social media related to specific stocks, sectors, or markets. Positive sentiment may lead to long positions, while negative sentiment may trigger short positions.

Sentiment momentum strategy

Sentiment momentum trading strategies combine sentiment analysis with momentum indicators. Traders look for situations where sentiment is shifting rapidly in one direction, indicating a strong sentiment momentum. They enter positions aligned with the sentiment momentum, anticipating further price movement in the same direction.

Sentiment intraday trading strategy

Sentiment intraday trading refers to the practice of using sentiment analysis and indicators to make short-term trading decisions within the same trading day. Traders aim to capitalize on shifts in market sentiment and take advantage of intraday price movements based on the prevailing sentiment.

Sentiment analysis for trading

Following are the steps for trading with sentiment analysis.

Sentiment Analysis in Trading steps

Step 1 - Data collection

Collect relevant text data from financial news articles, social media platforms, or online forums. You can use APIs or web scraping techniques to gather the data.

Step 2 - Data preprocessing

Clean and preprocess the collected text data to remove noise, irrelevant information, and standardise the text format. This step may include removing special characters, punctuation, converting text to lowercase, and removing stop words (common words with little contextual meaning).

Step 3 - Labelling the data

If you have labelled data available, assign sentiment labels (positive, negative, neutral) to your text data. This labelled data will be used for training and evaluating your sentiment analysis model. If labelled data is unavailable, consider using pre-labelled datasets or resorting to unsupervised learning techniques.

Step 4 - Feature extraction

Convert the preprocessed text data into numerical features that can be used as input to the sentiment analysis model. Common techniques for feature extraction include bag-of-words, TF-IDF (Term Frequency-Inverse Document Frequency), or word embeddings such as Word2Vec or GloVe.

Step 5 - Model training

Choose a machine learning or deep learning model for sentiment analysis. Some popular choices include Naive Bayes, Support Vector Machines (SVM), Random Forests, or Recurrent Neural Networks (RNN) like LSTM (Long Short-Term Memory) or GRU (Gated Recurrent Unit). Split your labelled data into training and testing sets and train the model using the training data.

Step 6 - Model evaluation

Evaluate the performance of your trained sentiment analysis model using the testing data. Common evaluation metrics include accuracy, precision, recall, and F1-score. Make necessary adjustments to your model or preprocessing techniques if the performance is unsatisfactory.

Step 7 - Sentiment analysis on new data

Once you have a trained and evaluated model, you can use it to perform sentiment analysis on new, unseen text data. Preprocess the new data in the same way as your training data, extract features, and feed them into your trained model to predict the sentiment.

Step 8 - Integration into trading strategy

Integrate the sentiment analysis results into your trading strategy. For example, you can use sentiment scores or predicted sentiments as signals for making buy or sell decisions. Combine sentiment analysis with other technical or fundamental indicators to create a comprehensive trading strategy.

It must be noted that sentiment analysis is just one tool in the trading toolbox, and it should be used in conjunction with other analyses and factors for making informed trading decisions.

In this code, we first download the required NLTK resources and load positive and negative tweets from the Twitter corpus. We then preprocess the tweets by tokenizing, removing stopwords, and stemming the words.

The preprocessed tweets are converted into feature sets where each feature represents a stemmed word. We split the data into training and testing sets and trained a Naive Bayes classifier using the training data.

Finally, we perform sentiment analysis on new data by classifying the tweets using the trained classifier and calculating the sentiment analysis's accuracy.

The Python codes to fetch tweets using different methods such as Search method & filtering and cursor method are explained in detail in the course on Trading strategies with News and Tweets.

Sentiment analysis using Tweepy

There is a library called Tweepy for fetching real-time and historical data from Twitter. Tweepy is a Python library that provides an easy-to-use interface for accessing the Twitter API. It allows developers to write Python scripts to interact with Twitter, such as searching for tweets, posting tweets, accessing user profiles, and more.

Sentiment analysis using VADER

Another way to use sentiment analysis is through VADER (Valence Aware Dictionary and sEntiment Reasoner). VADER is a popular open-source sentiment analysis tool specifically designed for analysing text sentiment in social media. It is included in the Natural Language Toolkit (NLTK), a widely used Python library for natural language processing.

An example of VADER can be:

Output:
{'neg': 0.0, 'neu': 0.259, 'pos': 0.741, 'compound': 0.8619}

In the output above,

  • neg: 0.0 indicates the absence of negative sentiment in the text.
  • neu: 0.259 indicates that approximately 25.9% of the text is considered neutral.
  • pos: 0.741 suggests that around 74.1% of the text is considered positive.
  • compound: 0.8619 represents the compound score, which is a normalised and aggregated score that ranges from -1 to 1. In this case, a compound score of 0.8619 indicates a highly positive sentiment.

These scores collectively provide an overview of the sentiment expressed in the text. Hence, the sentiment is positive, as indicated by the high positive score and the compound score close to 1.
