What is Upper Circuit? What Happens When Stock Hits Upper Circuit
Upper circuit is the maximum price a stock can reach on a given trading day. It is a percentage-based limit set from the previous close. Once a stock hits this price, it cannot trade any higher for the rest of that session. Only sell orders are accepted at the circuit price, but since sellers are rare at that level, very few trades actually happen.
Say a stock closed at Rs.100 yesterday and has a 20% circuit filter. Today, its upper circuit is Rs.120. Once the price reaches Rs.120, it is locked. Thousands of buy orders may be waiting at Rs.120, but there are barely any sellers willing to sell at that price. The stock is essentially frozen at the top.
Why does a stock hit upper circuit?
Stocks hit the upper circuit when buying demand is overwhelmingly stronger than selling supply. This usually happens because of a major positive development. Strong quarterly results, a large contract win, a favourable regulatory decision, or a sector-wide rally can trigger intense buying that pushes the price to its maximum permitted level within minutes.
In small-cap and micro-cap stocks, upper circuits can also be triggered by speculative buying based on rumours or operator activity. Not every upper circuit is a signal of genuine business strength. The reason behind the move matters more than the move itself.
What happens when a stock is at upper circuit?
| What Happens | Details |
|---|---|
| Price is frozen | No further price increase possible for the day |
| Only sell orders accepted | But very few sellers are willing to sell |
| Buy orders queue up | Massive pending buy orders with no matching sellers |
| Low trade volume | Few trades actually execute at the circuit price |
| Next day opens higher | Often, the stock gaps up the next morning as well |
How can I buy a stock that is at upper circuit?
It is very difficult. When a stock is at upper circuit, there are far more buyers than sellers. You can place a buy order at the circuit price, but it will join a long queue. Orders are matched on a time-priority basis, so the earliest orders have a better chance. In practice, most retail investors are unable to buy stocks that are consistently hitting upper circuits.
This is one reason why chasing upper circuit stocks is risky. By the time you manage to buy, the stock may have already moved significantly from where the rally started. If it reverses, you are buying near the peak.

Frequently Asked Questions
A stock has been hitting upper circuit for five consecutive days. Is it safe to buy?
Consecutive upper circuits often happen in small-cap and micro-cap stocks and can be driven by genuine demand or by speculative manipulation. Five consecutive days of upper circuit with very low traded volume is a warning sign because it means price is rising without meaningful trading activity. There is a risk that when the circuit breaks and normal trading resumes, the price can fall sharply as early buyers take profits.
Can I sell a stock that is at upper circuit?
Yes, you can place a sell order at the circuit price. Since there are many buyers waiting, your sell order has a high probability of getting executed if you are willing to sell at the upper circuit price. The challenge at upper circuit is buying, not selling.
Does upper circuit reset the next day?
Yes. The upper circuit for the next day is calculated based on today's closing price, not yesterday's. If the stock closed at Rs.120 today (at upper circuit) and has a 20% filter, tomorrow's upper circuit is Rs.144 and its lower circuit is Rs.96.
Do all stocks have the same circuit limit percentage?
No. SEBI and exchanges assign different circuit filter percentages based on the stock's characteristics. The common levels are 2%, 5%, 10%, and 20%. Highly liquid stocks in the F&O segment typically have no circuit limits because the derivatives market provides additional risk management mechanisms.
Is there a way to know which stocks might hit upper circuit tomorrow?
There is no reliable way to predict upper circuits. Stocks hit upper circuits based on news developments, earnings surprises, or sudden demand surges that are not predictable with certainty. Anyone claiming to consistently predict upper circuit stocks is likely engaging in speculation or manipulation. Be cautious of social media tips promising upper circuit calls.
