Upper Circuit and Lower Circuit

Introduction

Navigating the stock market can be challenging, especially when dealing with unpredictable price swings. Investors often encounter terms like upper circuit and lower circuit, which are crucial in controlling daily price movements of stocks within the circuit in the share market. These terms not only impact individual stocks but also play a significant role in maintaining stability within the market. In this blog, we’ll delve deep into what upper and lower circuits mean, how they work, their significance, and how to strategise trading within these limits. 

What Is an Upper Circuit?

An upper circuit is the maximum limit to which the price of a stock is allowed to rise in a single trading day. When a stock hits its upper circuit, it indicates significant buying interest, pushing the price up to the maximum daily permissible level as determined by stock exchanges like the National Stock Exchange (NSE) and the Bombay Stock Exchange (BSE). At this stage, further trading cannot increase the price for the day and only buy orders remain in the market, leading to a scenario known as only buyers.

Key Features of the Upper Circuit:

  1. Indicates Strong Demand: When a stock hits its upper circuit, it is a sign that investors have high confidence in its potential or have responded positively to recent news.
  2. Only Buyers Scenario: Once a stock reaches its upper circuit, there are no sellers at that price level, leaving only buyers interested.
  3. Price Ceiling for the Day: Once the upper circuit is hit, the stock cannot increase further for the remainder of the trading session.

Example of an Upper Circuit Stock

For instance, if Reliance Power experiences a surge that is favourable due to favourable quarterly results or significant developments, it might hit its upper circuit, showing only buyers in the market for the rest of the day.

What Is a Lower Circuit?

A lower circuit in share is the opposite of an upper circuit. It is the minimum limit to which a stock’s price can drop in a single trading day. When a stock reaches its lower circuit, it signals intense selling pressure, and the price hits the maximum allowable drop. In this situation, only sell orders remain in the market, creating an only-sellers scenario. This often results from adverse news or a negative sentiment shift.

Key Features of the Lower Circuit:

  1. Reflects High Selling Pressure: A stock that hits its lower circuit often indicates panic selling or a significant lack of investor confidence.
  2. Only Sellers Scenario: When the lower circuit is hit, the price can’t go any lower, and only sellers are available in the market, with few to no buyers at that price level.
  3. Daily Price Floor: Once the lower circuit is hit, the stock price cannot drop further for that trading session.

Example of a Lower Circuit Stock

Imagine Maan Aluminium experiencing a sudden decline in sales or a regulatory issue, which leads to a drop in investor confidence. In such cases, the stock could hit its lower circuit, with only sellers remaining in the market.

How Upper and Lower Circuits Work

Upper and lower circuits are mechanisms implemented by stock exchanges to regulate extreme price movements of stocks or securities within a single trading session. The upper circuit represents the maximum percentage increase allowed in the price of a stock for that day, while the lower circuit signifies the maximum percentage decrease permitted. These limits are calculated based on the previous closing price of the stock.

When a stock reaches its upper circuit, the system halts trading to prevent further price increases, allowing only buy orders with no sellers. Conversely, when a stock reaches its lower circuit, the system pauses trading to stop further price declines, leaving only sell orders with no buyers. This regulatory measure, enforced by the Securities and Exchange Board of India (SEBI), aims to promote stability in the stock market by curbing excessive volatility.

How Are Circuit Limits Determined?

Circuit limits are generally set as a percentage of a stock’s previous closing price and vary based on the stock’s trading volume, volatility, and market capitalisation. Typically, these limits range from 2% to 20%. Stocks with high volatility may have tighter circuit limits to control sudden price swings, while more stable stocks may have broader limits.

Factors Influencing Circuit Limits:

  1. Stock Volatility: Highly volatile stocks usually have narrower limits to help manage rapid price fluctuations.
  2. Market Capitalisation: Larger, more stable stocks often have broader circuit limits as they have a higher capacity to absorb large trades.
  3. Historical Data: Exchanges use past trading patterns and average volumes to determine appropriate limits for each stock.

Why Do Upper and Lower Circuits Matter?

The upper and lower circuits play a vital role in ensuring stability and fairness in stock markets by setting predefined price limits for individual stocks. These limits help prevent extreme price fluctuations within a single trading session, thus maintaining market stability and preventing panic-driven volatility.

Market Stability:

Circuit limits are designed to avoid excessive swings in stock prices, which can destabilise the market. By capping price changes within a range, they create a more orderly environment, allowing investors to make decisions without the chaos of sudden, drastic price moves.

Investor Protection:

Circuit limits serve as a safeguard for investors, especially during periods of high volatility. For instance, a stock hitting the lower circuit prevents further immediate losses in a single day, allowing investors to assess the situation without fear of runaway prices.

Improved Liquidity Management:

Extreme price changes can cause liquidity issues, making it difficult for trades to execute at fair prices. Circuit limits help balance supply and demand by slowing down movements, ensuring trades occur more smoothly, and maintaining fairer pricing.

In sum, the upper and lower circuits act as essential regulatory mechanisms that contribute to a more stable, transparent, and balanced market environment.

Advantages and Disadvantages of Upper and Lower Circuits

Advantages:

  1. Prevent Market Manipulation and Crashes: By capping the daily price movement, upper and lower circuits help prevent market manipulation and sudden crashes, ensuring a more orderly market.
  2. Reduce Volatility: These circuits act as a buffer against extreme volatility, providing a cooling-off period for investors to make informed decisions rather than reacting impulsively.
  3. Discourage Panic Selling: Lower circuits can help prevent panic selling by halting trading, giving investors time to reassess their positions and market conditions.

Disadvantages:

  1. Limit Potential for High Short-Term Gains: For traders looking to capitalise on rapid price movements, circuit limits can restrict the potential for high short-term gains.
  2. May Force Holding Onto Declining Stocks: Investors may be forced to hold onto stocks that are hitting their lower circuit, as selling opportunities become limited due to the lack of buyers.

Upper Circuit Stocks: The Only Buyers Scenario

When a stock hits its upper circuit, the situation often results in a only buyers scenario. This means that buyers are willing to purchase at the highest price, but sellers are unavailable, leading to an imbalance. Here’s a deeper look at how this scenario unfolds:

  1. Only Buyers in NSE and BSE: In popular stocks on the NSE or BSE, hitting an upper circuit can lead to a queue of only buyers, especially if driven by strong investor sentiment.
  2. Stock Sentiment: When a stock hits the upper circuit frequently, it may indicate high investor confidence, sometimes fueled by speculation or recent positive news. However, it’s essential to be cautious, as frequent upper circuits may also signal overvaluation.

Example of Upper Circuit Stocks:

For instance, technology stocks have often seen high demand due to growth in the digital sector, which may drive them into upper circuits. Upper circuit stocks in such high-demand sectors can attract speculative investors aiming for short-term gains.

Lower Circuit Stocks: The Only Sellers Scenario

In contrast, a stock that hits its lower circuit faces a only sellers situation. This means that no buyers are available at the lower circuit price, leading to a significant drop in liquidity. Here’s how this scenario typically plays out:

  1. Only Sellers in NSE or BSE: When a stock hits the lower circuit on exchanges like NSE or BSE, it usually signals a drastic shift in investor sentiment, driven by negative news or disappointing financial results.
  2. Caution for Investors: Lower circuit stocks can be risky, especially if they remain locked in the lower circuit for multiple sessions. This often signals underlying issues, and potential investors should investigate the reasons behind the drop.

Example of Lower Circuit Stocks:

Imagine a small-cap stock facing regulatory scrutiny or a sudden loss in business. Investors may panic, pushing the stock into its lower circuit and resulting in only sellers as everyone rushes to exit their positions.

Regulatory Goals for Implementing Upper and Lower Circuits

The primary goal of implementing upper and lower circuits is to maintain market stability and prevent extreme price movements. These circuits are designed to protect investors from drastic single-day price fluctuations and promote a stable trading environment. By setting predefined limits on price changes, upper and lower circuits help ensure that the market operates in an orderly manner, reducing the risk of panic-driven volatility and fostering investor confidence.

Trading Strategies for Upper and Lower Circuit Stocks

Trading in stocks near their upper and lower circuit limits can be lucrative but carries high risk. Here are some strategies to consider:

1. Momentum Trading with Upper Circuit Stocks

  • Identify Continuation Trends: Momentum traders often look for stocks that hit the upper circuit and continue rising. However, these trades should be backed by strong fundamentals to avoid buying overhyped stocks.
  • Use Indicators: Technical indicators like Moving Averages and Relative Strength Index (RSI) can help confirm if the upward trend is sustainable or if a reversal is likely.

2. Contrarian Strategy for Lower Circuit Stocks

  • Value-Based Approach: Investors may see stocks hitting their lower circuits as potential value buys. However, it’s essential to analyse the fundamentals to determine if the stock is genuinely undervalued.
  • Avoid Value Traps: Not all lower circuit stocks are good buys. Some may continue falling due to poor fundamentals, making them risky investments without in-depth analysis.

3. Risk Mitigation Techniques

  • Use Stop-Loss Orders: Circuit stocks are volatile, so it’s wise to use stop-loss orders to manage potential losses, especially in lower circuit stocks.
  • Set Entry and Exit Points: For both upper and lower circuit trades, set clear entry and exit points to protect your investments.

Trading Strategies for Upper and Lower Circuit Stocks: A Detailed Guide

Trading in stocks near their upper and lower circuit limits can provide unique opportunities for profit, but it also involves substantial risks due to heightened volatility. Circuit stocks tend to show drastic price movements, which means a well-planned strategy is essential to make the most of these situations. Below, we’ll explore effective strategies to manage these trades while minimising risk.

1. Momentum Trading with Upper Circuit Stocks

Momentum trading is based on the principle of “buying high and selling higher.” When a stock hits its upper circuit, it has reached the maximum daily increase allowed by the exchange, indicating strong demand and often signalling upward momentum. Here’s how to approach momentum trading in this scenario:

The first step is to determine if the stock’s upward movement is part of a sustained trend or just a short-lived surge. Continuation trends are those where the stock shows potential to continue its upward trajectory even after hitting the upper circuit. To identify this, it’s essential to monitor recent news, corporate announcements, and overall market sentiment regarding the stock. Positive news, such as better-than-expected earnings, new contracts, or industry growth, can push stocks into an upper circuit multiple times over several days, indicating continued interest and confidence.

Use Indicators

Technical indicators like the Moving Average (MA) and Relative Strength Index (RSI) can help assess the sustainability of an upward trend. Moving averages smooth out price data to identify trends, with shorter-term averages (like the 20-day MA) signalling momentum. If the price continues to stay above this moving average, it can indicate that the trend has momentum.

RSI is another useful tool; it ranges from 0 to 100 and can help detect when a stock is overbought (above 70) or oversold (below 30). When the RSI is approaching overbought levels, it might indicate that the stock is nearing a temporary top. Watching for these signals can prevent buying into a stock just as it peaks, enabling a more strategic entry.

2. Contrarian Strategy for Lower Circuit Stocks

The contrarian approach can be effective for lower circuit stocks but requires a discerning eye, as it involves buying stocks that have hit their maximum allowable drop. A lower circuit often reflects heavy selling, which can be triggered by market panic or negative news. Here’s how to navigate this:

Value-Based Approach

In certain cases, a stock’s price may fall sharply due to temporary or external factors that don’t fundamentally impact the company’s long-term potential. For instance, an industry-wide dip due to broader market concerns can bring down prices without affecting a company’s individual health. A value-based approach involves identifying these stocks as potentially undervalued and purchasing them in anticipation of a rebound.

However, this approach requires an in-depth fundamental analysis. Key areas to review include the company’s financial statements, debt levels, and industry position. By understanding the core value of the business, investors can determine if the lower circuit price truly represents a bargain.

Avoid Value Traps

A value trap occurs when a stock seems undervalued but continues to decline due to fundamental weaknesses, such as high debt or declining sales. Not all lower circuit stocks are value buys, so avoid stocks with deteriorating financials or significant operational challenges. A thorough analysis helps prevent investing in stocks with ongoing issues that could lead to further losses.

3. Risk Mitigation Techniques

Managing risk is essential when trading volatile circuit stocks. Here are some methods to protect your investments:

Use Stop-Loss Orders

A stop-loss order is a pre-set instruction to sell a stock if it reaches a certain price, limiting potential losses. In circuit trading, this is particularly valuable because prices can move sharply against you. Setting a stop-loss level helps limit downside risk if the stock unexpectedly reverses direction.

Set Entry and Exit Points

Determining entry and exit points is vital for both upper and lower circuit trades. For upper circuit stocks, monitor indicators to enter when the momentum looks sustainable. Plan your exit based on technical targets or specific profit margins rather than holding indefinitely, as circuit stocks can see swift reversals.

For lower circuit stocks, wait until the selling pressure shows signs of easing and buying interest begins to reappear. Entering only when the price stabilises and planning a target exit price can help capture the recovery without holding too long.

Common Misconceptions About Upper and Lower Circuits

  1. Not a Guarantee Against Market Volatility: Upper and lower circuits are not a foolproof guarantee against market volatility. They are regulatory measures aimed at mitigating the impact of extreme price movements, but they do not eliminate volatility altogether.
  2. Do Not Prevent Price Movements: These circuits do not prevent price movements; they merely limit the extent of price fluctuations within a single trading session. Prices can still move significantly over multiple sessions.
  3. Applicable to Stock Indices: Upper and lower circuits are not unique to individual stocks. They can also be applied to stock indices, helping to prevent market-wide panic selling or buying frenzies. This ensures that the broader market remains stable even during periods of high volatility.

By understanding these mechanisms and their implications, investors can navigate the stock market with greater confidence and make more informed trading decisions.

Conclusion

Circuit limits in the stock market help manage volatility by capping extreme price swings in a day. While upper circuits signal strong demand, lower circuits may indicate selling pressure. Trading these stocks can be profitable but risky, so using stop-loss orders, technical indicators, and fundamental analysis can aid in building a balanced, growth-focused portfolio.

Stocks hit the lower circuit due to high selling pressure, which may result from negative news or investor concerns about the company’s performance.

Can you buy or sell stocks in a circuit limit?

Yes, but trading may be limited. If there are only buyers at the upper circuit, it’s challenging to find sellers, and vice versa for the lower circuit.

What are only buyers and only sellers in stock trading?

Only buyers occurs at the upper circuit when no sellers are present, while only sellers happens at the lower circuit when there are no buyers.

Are upper circuit stocks good for investment?

Upper circuit stocks may indicate strong demand, but they can also be risky if driven by speculation. It’s best to analyse the fundamentals.

How are circuit limits calculated?

Circuit limits are usually set as a percentage of the previous day’s closing price, based on volatility and other factors.

Do circuit limits apply to all stocks?

Most stocks on exchanges like NSE and BSE have circuit limits, though highly liquid and large-cap stocks might have different rules or wider limits due to their ability to absorb higher trading volumes without extreme volatility.

Is it possible to exit a position in a lower circuit stock?

Exiting a lower circuit stock can be difficult since there are no buyers available, leading to a situation where sellers are essentially trapped. This is why it’s important to approach lower circuit stocks with caution.
