Market Sentiment Overview

Definition

You often hear the term “market sentiment” in investing. Market sentiment is actually the overall view and attitude of investors toward the market or a specific stock. Different financial research institutions have varying definitions of market sentiment. You can refer to the table below:

You can see that market sentiment focuses on investors’ psychology and emotions rather than company financials or economic data.

Impact

Market sentiment has a significant impact on price fluctuations and capital flows. When you analyze market sentiment, you will notice the following phenomena:

• Market sentiment reflects investors’ overall views of the market, influencing buying and selling activities.
• Emotional reactions often lead to irrational trading behavior, causing price fluctuations.
• Indicators such as VIX and the High-Low Index help investors assess market sentiment, thereby affecting capital flows.
• When market sentiment is bullish, prices rise; when it is bearish, prices fall.
• Social media platforms can amplify traders’ and investors’ emotions, further impacting market sentiment and price fluctuations.

If you can promptly grasp changes in market sentiment, you can better understand the reasons behind market fluctuations.

Retail Investor Sentiment Cycle

Retail investors’ sentiment also exhibits cyclical changes. Behavioral finance studies show that investors’ emotions fluctuate with time and market performance. You can refer to the table below to understand the typical sentiment cycle:

You will find that investors are more willing to invest capital when market returns are high, while during market volatility or declines, capital liquidity increases rapidly, leading to bottom-fishing behavior. For example, during significant U.S. market declines in 2008 and 2020, investor capital transfers increased notably. Understanding these cycles can help you analyze market sentiment more scientifically and optimize investment strategies.

Methods for Analyzing Market Sentiment

When investing, analyzing market sentiment can help you better understand market fluctuations and capital flows. You can use various methods and tools to systematically assess the psychological state of market participants. Below, I will detail several mainstream methods to help you get started quickly.

Sentiment Indicators

You can use various sentiment indicators to analyze market sentiment. These indicators are widely used in global financial markets and can reflect investors’ fear, greed, and expectation changes. Common sentiment indicators include:

• CBOE Volatility Index (VIX): You can observe market fear through the VIX index. When investors are concerned about future market uncertainty, the VIX rises significantly. For example, during the 2008 financial crisis and the 2020 pandemic, the VIX surged past 80, indicating extreme panic.
• NYSE High-Low Index: You can track the number of stocks hitting 52-week highs and lows. Extreme values often signal that market sentiment has reached extremes, indicating clear bullish or bearish signals.
• NYSE 200-Day Moving Average: You can monitor the proportion of stocks trading above their 200-day moving average. An increasing proportion suggests optimistic market sentiment.
• Odd-Lot Trading Statistics: You can observe individual investors’ trading behavior. During market extremes, odd-lot trading volumes surge, often considered a contrarian indicator.
• Commitments of Traders (COT) Report: You can use the COT report to understand position distributions in the futures market. Extreme speculative positions often signal an impending market reversal.

Additionally, the Fear & Greed Index is a commonly used tool for analyzing market sentiment. The table below outlines its main features:

You can use these indicators to quantitatively analyze market sentiment changes, aiding your investment decisions.

Social Media Trends

You can track market sentiment through social media platforms. Many professional institutions use machine learning algorithms and human verification to analyze discussions on social media. These methods can accurately capture investors’ emotional changes with up to 95% confidence levels and low error rates. Human verification also identifies complex emotions and subtle nuances, ensuring accurate data classification.

You can follow trending topics and keywords on platforms like Twitter and Reddit to observe investors’ discussion intensity regarding specific stocks or sectors. A sudden spike in a topic often signals an impending change in market sentiment. You can combine social media data to adjust your investment strategies in a timely manner.

Tip: You can use professional sentiment analysis tools (such as Sentiment Investor, StockTwits, etc.) to automatically collect and analyze social media data, improving analysis efficiency.

Financial News

You can analyze market sentiment through financial news headlines. The sentiment of news reports directly affects investors’ psychological expectations, especially retail investors. The table below shows the statistical relationship between news sentiment and market fluctuations:

You can follow headlines from mainstream financial media to analyze the sentiment of reports. When news is overwhelmingly optimistic, market sentiment often leans bullish; when news is filled with pessimistic expectations, market sentiment tends to turn bearish. You can combine news sentiment analysis to assist in judging short-term market trends.

Broad Market and Sectors

You can analyze overall market sentiment changes by observing broad market and sector performance. Positive sentiment typically drives price increases, while negative sentiment leads to price declines. After events, cumulative abnormal return (CAR) patterns show clear divergence, indicating that sentiment changes have a lasting impact on the market. Different company groups have varying sensitivity to sentiment changes, with financial services companies being the most responsive.

You can regularly track the performance of indices like the S&P 500 and Nasdaq, combined with sector rotation, to determine the dominant direction of market sentiment. You can also monitor capital flow data to analyze which sectors are favored by investors and which are being sold off, optimizing your investment portfolio.

You can combine sentiment indicators, social media trends, financial news, and broad market/sector performance to analyze market sentiment from multiple dimensions, enhancing the rigor and effectiveness of investment decisions.

Technical Integration

In actual investing, you can combine sentiment analysis with technical analysis to enhance the effectiveness of trading strategies. Technical analysis focuses on price trends and trading volume, while sentiment analysis helps you understand the psychological changes of market participants. Combining the two allows you to more comprehensively seize market opportunities.

Many studies find that hybrid strategies outperform single strategies. You can refer to the table below to understand the returns of different strategies:

You can see that strategies combining sentiment analysis and technical indicators significantly outperform simple buy-and-hold approaches. When analyzing market sentiment, you can use technical indicators like MACD and moving averages, combined with social media sentiment data, to determine buy and sell timing. For example, when technical indicators show a buy signal and social media sentiment is also positive, you can consider increasing your position. Conversely, if technical indicators weaken and sentiment data turns pessimistic, you can choose to reduce your position or stay on the sidelines.

You can also monitor sentiment changes on platforms like Twitter. Statistical data shows that Twitter sentiment is positively correlated with trading volume, profits, and market returns. You can combine these data to make more scientific trading decisions.

Case Studies

In practice, you can learn from the approaches of large investment institutions. Many well-known investors and fintech companies have applied sentiment analysis to investment decisions. The table below shows how some institutions apply sentiment analysis and their results:

You can also refer to the following practices:

• Schwab’s STAX tool provides investors with a quantitative view of trading behavior, helping you track market sentiment.
• This tool analyzes buying and selling activities in portfolios, industries, and individual stocks, supporting more rational investment decisions.

In real-world scenarios, sentiment analysis can help you predict the impact of public sentiment on stock prices. For example, after a Hong Kong-licensed bank launched a new product in the U.S. market, widespread positive discussions on social media boosted investor confidence, leading to a stock price increase. Conversely, if negative news or poor earnings reports emerge, market sentiment may turn pessimistic, causing stock prices to fall. By analyzing market sentiment, you can adjust your holdings in a timely manner to reduce risks.

You can also focus on the relationship between corporate tweet frequency and market activity. Studies show a causal relationship between corporate tweet frequency and market activity. Positive sentiment is also related to a company’s bankruptcy probability. By combining this information, you can better grasp market dynamics.

Strategy Formulation

You can follow these steps to formulate a trading strategy based on sentiment analysis:

1. Understand market sentiment. You need to regularly collect and analyze sentiment data to determine whether the overall market sentiment is optimistic or pessimistic.
2. Use sentiment indicators. You can focus on indicators like VIX, the Fear & Greed Index, and social media sentiment to assist in identifying market inflection points.
3. Integrate sentiment into trading strategies. You can set specific buy and sell rules. For example, when sentiment indicators are extremely optimistic, consider reducing positions; when extremely pessimistic, consider buying in batches.
4. Backtest. You can use historical data to test the strategy’s effectiveness, evaluating risks and returns.
5. Implement in real time. You need to dynamically adjust holdings based on the latest sentiment data.

You can also refer to the following points:

• Assess market sentiment to capture sentiment changes.
• Pay attention to the impact of news and major events.
• Practice risk management to avoid losses from excessive sentiment fluctuations.
• Integrate sentiment analysis into algorithmic trading or event-driven trading.

When analyzing market sentiment, combining technical analysis and capital flows can enhance the rigor and practicality of your strategies. Through continuous practice and optimization, you can gradually develop an investment system suited to your needs.
