Market Mood Index: Meaning, Importance, and How It Works

For investors, determining the optimal times to buy or sell assets like mutual funds and shares is a crucial concern. While many look to financial analysts for insights into market trends, tools like the Market Mood Index offer valuable guidance.

This index helps investors make informed decisions by providing a snapshot of current market sentiment. This article explores what is Market Mood Index, explaining how it functions in assessing India's daily market sentiment.

What is Market Mood Index (MMI)?

The Market Mood Index is a market indicator that measures the sentiment of fear and greed in financial markets. It was developed by MarketPsych, a US-based quantitative behavioural finance research firm, in 2004 to quantify how emotions drive market behaviour beyond traditional analysis.

Importance of Market Mood Index

The Market Mood Index (MMI) is a tool that helps in identifying market sentiment. It shows how investor psychology might be having a bigger impact on the market.

If the MMI indicates higher greed sentiment, we often see increase in investments or a 'bullish trend'. When there's a lot of fear, markets usually drop, with more sales of shares in market. Spotting these trends can help investors assess risks and decide what to do next.

 While the MMI offers meaningful insight into market psychology, it is most effective when used alongside fundamental and technical analysis. Together, these tools contribute to a more balanced and informed view of market behaviour.

How Does Market Mood Index Work?

The Market Mood Index in India works the same way as the one used globally. However, to accurately gauge the environment of the Indian stock market, it incorporates specific elements such as:

Foreign Institutional Investor (FII) –

By tracking the flow of money from FIIs into Indian markets. If purchases exceed sales, the MMI shifts towards ‘Greed’, while higher sales than investments signal ‘Fear’.

Volatility and Skew (India VIX) –

The MMI includes the India Volatility Index (VIX) to assess market fluctuations. A higher VIX suggests increased uncertainty or apprehension in the market, while a lower VIX indicates investor confidence in market trends.

Market Benchmarks –

The MMI also analyses major indices such as the Nifty 50 and Sensex to identify when markets are overbought (greed) or oversold (fear).

Zones and Components of the Market Mood Index

The market mood index chart has five zones:

MMI Zone

Description

Extreme Fear (0-30)

Indicates high pessimism; market may be undervalued and potentially oversold.

Fear (30-50)

Cautious sentiment: investors are generally risk averse.

Neutral (50)

Balanced sentiment; no strong bias towards buying or selling.

Greed (50-70)

Investors are optimistic; market may be approaching overbought levels.

Extreme Greed (70 -100)

Signals overconfidence; market may be overvalued and due for a correction.

Key Components of Market Mood Index

Aside from VIX and FII, the other components of Market Mood Index are:

  • Price Momentum - Indicates whether the market is gaining or losing strength.
    • Strong up move indicates optimism (greed)
    • Weak or falling momentum indicates caution (fear)
  • Put-Call Ratio – Indicates how investors are positioned within the options market.
    • Increased put volumes indicate hedging or bearishness
    • Increased call volumes indicate bullishness
  • Market Breadth - Indicates how widespread a market movement is.
    • More stocks advancing than declining = positive breadth
    • Narrow participation can reveal hidden weakness
  • Trading Volume – Assesses the proportion of rising versus falling stocks alongside the total trading activity.
    •   High volume and broad participation suggest enduring positive sentiment.
    •   Low volume or restricted participation may signal potential weaknesses in the market.

Limitations of Using MMI

Although the market mood indicator provides useful information on investor behaviour, depending on it for investment decisions can lead to exposure to risks for your investments. It’s important be aware of limitations of Market Mood Index such as:

  • Lagging signals:Similar to many sentiment indicators, it tends to validate trends after they have begun instead of anticipating them.
  • Short-term noise: Intraday changes in the market mood index chart can sometimes fail to represent fundamentals of the trade.
  • No outcome guarantee: Market sentiment may change rapidly, and thus it is not advisable to invest by relying solely on market mood index without complementing technical or macroeconomic analysis.

How to Use Market Mood Index in Trading?

The Market Mood Index (MMI) can help traders gauge the underlying sentiment before making moves. Here's how you can use it effectively during trading decisions:

  1. Step 1: Check the MMI Reading – Begin by viewing the Market Mood Index today to know the investor sentiment in the market.
  2. Step 2: Compare Market Trends – Compare the market mood indicator with other market trends such as the price movement to confirm trend strength.
  3. Step 3: Time Your Trades Based on Sentiment Extremes
    Traders often consider entering during fearful periods (potential undervaluation) and exiting during greed (possible overvaluation).

Practical Example of Using Market Mood Index

Suppose the MMI index is at 85, indicating extreme greed, and major indices like the Nifty 50 or Sensex are near record highs. A trader holding short-term positions may decide to book profits, expecting a potential correction due to overheated sentiment.

On the other hand, if the MMI index falls to 25, suggesting fear, and the market is trading lower, long-term investors might view this as an opportunity to buy quality stocks at discounted prices. Using the market mood index in this way can help align trading actions with prevailing sentiment.

Using MMI in Investment Strategies

The Market Mood Index (MMI) can support a variety of investment strategies by helping investors gauge sentiment and make better decisions. Here’s how it fits into different approaches:

1. Contrarian Strategy

This involves doing the opposite of market sentiment. If the MMI index shows extreme fear, prices may be undervalued, offering a potential buying opportunity. When it reflects extreme greed, it could be a good time to reduce positions or book profits.

2. Trend Following

Traders watch the direction of the MMI. A rising index may suggest growing optimism and a possible uptrend. A falling MMI may point to caution and a shift towards defensive positioning.

3. Risk Management

Changes in the MMI can help you adjust exposure. During periods of high fear, you may reduce risk. As optimism returns, you can reassess and increase equity allocation where appropriate.

4. Entry and Exit Planning

You can use the MMI to time market entries and exits. For example, extreme fear readings may signal attractive entry levels, while high optimism may indicate a good time to pare back exposure.

5. Sector Rotation

Shifts in market mood may also guide sector choices. In times of optimism, cyclical and growth stocks often gain favour. During fear, investors may prefer defensive sectors or assets.
