Definition

You can think of the bull-bear ratio as an indicator for measuring market sentiment. It reflects the proportion of bullish (long) and bearish (short) investors in the market. By decoding bull and bear signals, you can gain clearer insight into the attitudes of market participants. The bull-bear ratio is commonly used in the U.S. stock market to help you determine whether the market is leaning optimistic or pessimistic.

Calculation Method

You can calculate the bull-bear ratio using a simple formula. The table below illustrates the commonly used calculation method:

You only need to collect the number of bullish and bearish views in the market and plug them into the formula. A higher result indicates stronger bullish sentiment, while a lower result suggests bearish sentiment dominates.

Principle

The theoretical foundation of the bull-bear ratio is straightforward. You can use it to measure market sentiment.

• Market sentiment reflects investors’ overall attitude toward current and future prices.
• This attitude can be positive, neutral, or negative.
• Market sentiment indicators measure the market’s feelings and emotions.
• They can indicate strong bullish sentiment, strong bearish sentiment, or something in between.
• The bull-bear ratio focuses not on price or trading volume but on changes in investor sentiment.

By observing changes in the bull-bear ratio, you can better grasp market trends and risks, providing valuable reference points for your investment decisions.

Decoding Bull and Bear Signals and Market Sentiment

Sentiment Interpretation

You can use the bull-bear ratio to quickly decode bull and bear signals and understand the market’s current sentiment. When the bull-bear ratio is high, it indicates that bullish investors dominate, and the overall market sentiment is optimistic. When the bull-bear ratio is low, bearish sentiment prevails, and investors are generally cautious or pessimistic.

You can think of the bull-bear ratio as a “thermometer” for market sentiment. When you see the bull-bear ratio steadily rising, it indicates growing market confidence, with investors more willing to buy. Conversely, a declining bull-bear ratio signals weakening confidence, with investors more inclined to sell or stay on the sidelines.
Many studies focus on identifying market sentiment through data. For example, the study “A top-down approach to identifying bull and bear market states” proposes a flexible hierarchical approach to help you better capture market state transitions.
You can refer to the table below for an overview of related research:

Trend Identification

You can use the bull-bear ratio to determine whether the market is in a bull or bear phase. The bull-bear ratio not only reflects current sentiment but also helps you identify trend changes.

• When the bull-bear ratio remains at high levels, bullish forces dominate, typically indicating a sustained bull market phase.
• When the bull-bear ratio continues to decline, bearish forces strengthen, suggesting the market may be entering a bear phase.
• If the bull-bear ratio reaches extreme values, the market is often near a turning point, warranting your close attention.

You can combine different market cycles to understand the signaling significance of the bull-bear ratio. For example, in the U.S. market, the bull-bear ratio typically rises rapidly during the early stages of a bull market and declines noticeably during the early stages of a bear market.

Related research, such as Identifying bull and bear market regimes with a robust rule-based method, demonstrates how to use a single parameter to identify market states, reducing subjective judgment.

Applications of the Bull-Bear Ratio

Interpretation Steps

You can systematically interpret and apply the bull-bear ratio through the following steps to decode bull and bear signals and enhance your investment judgment:

• First, collect market sentiment data. You can refer to investor surveys, fund managers’ net stock exposure, and other information. Soft sentiment data often rebounds from highly bearish consensus, with sentiment fluctuating alongside price changes.
• Second, observe changes in the bull-bear ratio. You may notice that when the bearish/bullish ratio reaches extreme values, market complacency peaks, and price trends become fragile.
• Third, combine market cycle analysis. You can focus on the bull-bear ratio’s performance during bull and bear markets. For example, BofA’s private client sentiment indicator shows that while sentiment has rebounded from lows, it remains at bearish levels.
• Finally, conduct backtesting. You can backtest bull-bear ratio strategies under different market conditions (bull, bear, or sideways) to ensure their effectiveness across various environments. Use sufficient historical data samples to reduce overfitting risks and consider transaction costs to ensure realistic backtesting results.

You can divide backtesting into bull, bear, and sideways periods to analyze the performance of bull-bear ratio strategies in different market conditions, enhancing strategy reliability.

Case Study

You can refer to the following case study to understand the practical application of the bull-bear ratio in investing:

Suppose you are an investment advisor at a licensed Hong Kong bank, managing a U.S. stock portfolio for clients. You notice that recent investor sentiment charts show fund managers’ net stock exposure rebounding from a decade-low to near a decade-high. You observe that the bull-bear ratio remains consistently high, indicating a clearly optimistic market sentiment.

You decide to adjust your clients’ investment strategies in phases:

• When the bull-bear ratio is extremely high, you recommend that clients moderately reduce positions to mitigate risks from market complacency.
• When the bull-bear ratio falls back to neutral levels, you encourage clients to gradually increase positions to capture market rebound opportunities.
• Through backtesting, you find that the bull-bear ratio’s signals are more effective during bear market rebounds, helping clients seize market turning points in a timely manner.

The table below illustrates the performance of investment strategies combining the bull-bear ratio with market state predictions under different market conditions:

Through these cases, you can understand the specific role of the bull-bear ratio in investment decisions, enhancing risk management and trend identification capabilities.

Indicator Combinations

You can combine the bull-bear ratio with other technical indicators to optimize portfolio management:

• RSI (Relative Strength Index) below 30 is considered oversold, typically signaling bullish opportunities; above 70, it’s considered overbought, indicating bearish risks. You can combine the bull-bear ratio to determine whether the market is in an extreme sentiment range.
• Moving averages (MA) can help you identify price trends. When the 50-day MA crosses above the 200-day MA, it forms a “golden cross,” typically seen as a bullish signal. You can observe whether the bull-bear ratio rises simultaneously to further confirm market trends.
• By combining multiple indicators, you can improve the accuracy of your investment strategy. For example, when the bull-bear ratio is high and RSI is in the overbought zone, you might consider reducing positions; when the bull-bear ratio is low and RSI is in the oversold zone, you might consider increasing positions.

By decoding bull and bear signals and combining the bull-bear ratio with technical indicators, you can build a more scientific investment system, increasing the success rate of your investment decisions.

Limitations and Risks

Scope of Application

When using the bull-bear ratio, you need to understand its scope of application. The bull-bear ratio primarily reflects market sentiment, but its reliability varies under different market conditions.

• During periods of high inflation and economic recession, markets are more likely to enter bear phases, with declining investor confidence reducing the reference value of the bull-bear ratio.
• During economic recessions, many investors may choose to sell stocks and shift to safer assets, making the bull-bear ratio less accurate in reflecting true market trends.
• Historical data shows that while bear markets typically last a shorter time, their psychological impact on investors is prolonged, affecting their confidence in bull markets.

You need to consider the market environment to determine whether the bull-bear ratio’s signals are valid.

Risk Warnings

In actual operations, you may encounter situations where the bull-bear ratio fails. The table below illustrates typical events in the U.S. market where the bull-bear ratio did not accurately signal trends and the reasons behind them:

You also need to note that during bear markets, risk premiums rise, and long-term stock values decline more significantly. This suggests that the bull-bear ratio may not accurately predict market trends in extreme conditions.

Avoiding Pitfalls

When applying the bull-bear ratio, you may fall into common pitfalls.

• Past Performance Trap: You might make decisions based on historical data, but past performance does not guarantee future results.
• Greed Trap: Chasing rallies at bull market peaks can lead to buying at high valuations, increasing the risk of losses.
• Entry and Exit Timing: It’s difficult to perfectly time buying and selling. Understanding market cycles and valuations can help you make wiser decisions.

You need to analyze rationally and combine multiple indicators to avoid relying solely on the bull-bear ratio, enabling better risk management.

Strategy Recommendations

You can use the bull-bear ratio as a key reference for investment decisions. First, observe changes in the bull-bear ratio to gauge market sentiment. If the bull-bear ratio is at a high level, consider reducing stock positions to lower risk. When the bull-bear ratio is low, gradually increase positions to seize market rebound opportunities.

• You need to understand market cycles and adjust investment strategies in a timely manner. During bull markets, maintain patience and discipline to avoid chasing rallies blindly. In bear market phases, focus on extreme changes in market sentiment to identify potential reversal signals.
• You can adopt an opportunistic approach during market downturns, taking advantage of low sentiment periods to position in high-quality assets. This helps you build a more resilient portfolio for long-term growth.

Integrating into Investment Systems

You can combine the bull-bear ratio with other technical indicators to optimize your investment system. For example, combining RSI and moving averages can improve trend identification accuracy. You can set clear buy and sell rules to avoid emotional trading.

You can periodically review your investment strategy, analyzing the bull-bear ratio’s performance across different market environments. Through historical data backtesting, you can validate the strategy’s effectiveness and reduce subjective judgment.
