In the dynamic world of the stock market, prices of stocks can be highly volatile, causing sharp upward or downward movements in a short period of time. To curb extreme price fluctuations, mechanisms known as upper circuits and lower circuits are employed. These price limits help in stabilizing the market and protecting investors from panic-driven trading. In this blog, we will delve deep into what upper and lower circuits mean, how they work, and how traders and investors can use these mechanisms to their advantage.
What is an Upper Circuit?
An upper circuit is the highest price a stock can reach during a single trading session. Once the price hits this level, trading in the stock is halted to prevent further upward movement, which could cause a speculative bubble. The upper circuit is set by the stock exchanges and acts as a safeguard against extreme bullish movements in a stock’s price.
For example, if a stock’s upper circuit is set at a 10% increase, and the stock closes the previous day at ₹100, it can only rise to ₹110 during the next trading session. Once the price reaches this level, trading is halted to prevent the stock from being continuously bought at inflated prices.
Understanding the upper circuit can help investors gauge market sentiment during bullish trends, allowing them to make informed decisions about whether to hold or sell their stocks.

What is a Lower Circuit?
A lower circuit, on the other hand, is the lowest price a stock can fall to during a single trading session. Similar to the upper circuit, when a stock hits its lower circuit, trading is temporarily halted to prevent further downward movement, which could lead to panic selling. The lower circuit is especially useful in protecting traders and investors from significant losses.
For example, if a stock’s lower circuit is set at a 10% decrease, and the stock closes the previous day at ₹100, it can only drop to ₹90 during the next session. Once the stock hits this price, trading is suspended to stop a free fall.
How Do Upper and Lower Circuits Work?
The Securities and Exchange Board of India (SEBI) has implemented upper and lower circuits as part of its regulatory framework to stabilize the Indian stock market. These circuits, also known as price bands, are set by stock exchanges and are calculated as a percentage of the previous day’s closing price.
The primary purpose of these circuits is to prevent irrational price movements and provide investors with time to reassess their positions. When a stock reaches its upper or lower circuit, trading is temporarily halted to avoid chaotic buying or selling.
Table: Percentage Circuit Limits in the Indian Stock Market
| Stock Category | Percentage Circuit Limit |
|---|---|
| Highly Volatile Stocks | 5% |
| Moderately Volatile Stocks | 10% |
| Low Volatility Stocks | 20% |
The percentage varies based on the stock’s historical volatility, liquidity, and market sentiment.
How to Use Upper and Lower Circuits to Your Advantage?
1. Using Stop-loss Orders
Stop-loss orders are a vital tool for managing risk when trading in volatile stocks. By setting a stop-loss order at a price just above or below the lower circuit, investors can prevent significant losses. For instance, if a stock is nearing its lower circuit, placing a stop-loss order will automatically sell the stock when it reaches a predetermined price, helping minimize further losses.
2. Monitoring the Circuits
Investors should keep a close watch on the upper and lower circuits of the stocks they are invested in. Understanding how close a stock is to its circuit limits can provide valuable insights into market sentiment and help in making informed investment decisions.
3. Avoiding Herd Mentality
One common mistake is blindly following the market when a stock hits its upper or lower circuit. Just because a stock reaches the upper circuit doesn’t mean it will continue to rise indefinitely, and hitting the lower circuit doesn’t necessarily mean the stock will continue to fall. Always conduct your own research before making investment decisions.
4. Conducting Thorough Research
Before buying or selling stocks, it’s important to analyze the reasons behind their price movements. Look into factors such as the company’s earnings, debt levels, price-to-earnings ratio (PE ratio), shareholding patterns, and market sentiment. A stock hitting its upper or lower circuit could indicate either a temporary trend or a longer-term opportunity.
5. Benefiting from Opportunities
If you’re considering buying a stock and it hits the lower circuit, this could be an opportunity to buy at a low price. Similarly, when you’re ready to sell and the stock hits the upper circuit, it might be a good time to book profits.
Factors That Drive Upper and Lower Circuits
Several factors can cause a stock to hit its upper or lower circuit. These include:
- Political Unrest: Changes in political stability can affect investor confidence, causing stock prices to surge or plummet.
- Trade Agreements: Favorable or unfavorable trade deals can impact demand for certain stocks.
- Mergers and Acquisitions: Mergers often drive stock prices up, while acquisitions, particularly those involving debt, may lead to a stock’s lower circuit.
- Interest Rates: Rising interest rates may reduce investment, leading to lower stock prices, while lower rates can drive prices up.
- Financial Performance: Positive earnings reports can lead to an upper circuit, while poor performance may result in a lower circuit.
- Investor Confidence: Positive news about a company can drive up prices, while negative news can lead to lower prices.

How Circuit Breakers Affect Indices
In addition to individual stocks, upper and lower circuits are also applied to stock indices like the BSE Sensex and the Nifty 50. These index-level circuit breakers are triggered when the entire market moves by a certain percentage in a single day. In India, a 10%, 15%, or 20% rise or fall in a major index triggers a halt in trading.
Table: Circuit Breaker Rules for Indices
| Percentage Movement | Time of Day | Trading Halt Duration |
|---|---|---|
| 10% | Before 1 PM | 45 minutes |
| 10% | After 1 PM | 15 minutes |
| 15% | Before 1 PM | 1 hour 45 minutes |
| 15% | After 1 PM | 45 minutes |
| 20% | Anytime | Remainder of the day |
These circuit breakers help cool down the market during times of extreme volatility, allowing investors time to reassess their strategies.
Five Key Facts About Upper and Lower Circuits
Here are five essential things every investor should know about upper and lower circuits:
- Based on the Previous Day’s Price: Circuits are calculated based on the stock’s closing price from the previous trading session.
- Available on Stock Exchange Websites: Investors can easily find circuit limits for specific stocks on stock exchange websites.
- Initial 20% Circuit Limit: Most stocks start with a 20% circuit, though this can be adjusted based on volatility.
- Effect on Intraday Trades: When a stock hits its circuit, intraday trades automatically convert to delivery trades.
- No Sellers in Upper Circuit, No Buyers in Lower Circuit: When a stock hits the upper circuit, there are only buyers and no sellers, and vice versa for the lower circuit.
Using Circuit Breakers to Your Advantage
Here are some strategies for leveraging upper and lower circuits effectively:
- Plan Your Investments: By analyzing circuit limits, you can make informed decisions about short-term trading opportunities.
- Minimize Losses: Circuit filters help minimize losses during sharp declines by halting further trading when a stock hits its lower circuit.
- Research Stocks with Higher Circuits: Stocks with higher circuit limits often present greater growth potential, but they also carry higher risk.
- Avoid Overreliance on Circuits: While circuits provide valuable information, they are not a foolproof strategy. Be sure to consider other market conditions and factors before making decisions.
Conclusion
Upper and lower circuits are essential mechanisms designed to maintain stability in the stock market by preventing extreme price volatility. As an investor, understanding how these circuits work can help you make smarter investment decisions, protect your portfolio from unnecessary risk, and capitalize on opportunities when they arise. By staying informed and conducting thorough research, you can use circuits to your advantage in the stock market.
