Jurisdictions and stock exchanges have their own rules for what circuit breakers entail when they kick in, and for how long they are in place. Circuit breakers are triggered based on slightly different parameters on various exchanges, with trading suspended anywhere between 5 minutes – as is the case on the Hong Kong exchange – or an entire day.

New York Stock Exchange President Stacey Cunningham told CNBC that circuit breakers are a precautionary measure that can slow down for a minute.

The circuit breakers “are designed to slow trading down for a few minutes, to give investors the ability to understand what’s happening in the market, consume the information and make decisions based on market conditions,” she said.

A circuit breaker functions in the trading world the same way it does for electrical circuits in a home. When things get overloaded, it kicks in and shuts down the circuit.
