A circuit breaker is a regulation tool in financial markets that momentarily halts trade on an exchange to prevent panic selling and excessive volatility. Circuit breakers are intended to give investors time to analyze information and make more sensible trading decisions. These techniques contribute to market stability and shield investors from the potentially destabilizing impacts of rapid and large market fluctuations.
How Circuit Breakers Work
- Trigger Levels: Circuit breakers are activated when the price of an index or a stock exceeds predetermined percentage levels within a given time window. These thresholds are determined by the exchange or regulatory authority.
- trade Halt: When a circuit breaker is tripped, trade is suspended for a predetermined time. The duration of the halt varies according to the severity of the price movement and the exchange’s individual criteria.
- Resumption of trade: Following the cooling-off phase, trade restarts gradually or completely, allowing the market to normalize. If more severe price changes occur, additional circuit breakers may be activated.
Types of Circuit Breakers
- Market-Wide Circuit Breakers: These affect the whole market and are usually based on important indices, such as the S&P 500 in the United States. Market-wide circuit breakers contain numerous thresholds (e.g., 7%, 13%, and 20% drops), resulting in progressively longer trading halts.
- Single-Stock Circuit Breakers: These are specific to certain stocks and are triggered by large price movements in a short period of time. Single-stock circuit breakers help to prevent high volatility in certain equities.
Advantages of Circuit Breakers
- Stabilization: Circuit breakers serve to stabilize markets by preventing panic selling and providing time for information dissemination.
