The circuit breaker mechanism is primarily used as a financial monitoring tool to prevent extreme price volatility. This study explores whether after implementing the circuit breaker mechanism, the relevant policy will become more effective or will generate market panic and thus affect liquidity. Econometric analyses are used to verify the long-term and short-term impacts of a circuit breaker. The empirical results show that the liquidity has indeed decreased, but it did not exacerbate the investor's selling behavior due to the policy implementation. Furthermore, the price drop is more severe in the short-term, while the trade volume decrease is more significant in the long-term.
