Buckle Up: Markets Poised for More Volatility

Market Volatility, Trading Halts and Circuit Breakers

As the realization of a Trump win began to set in on election night in the U.S., Dow Jones Industrial Average futures dropped more than 800 points (but later recovered some of those losses). Meanwhile, futures on the S&P 500® Index fell more than 5%, triggering “circuit breakers” on the overnight futures trading (Globex) system.

So what is a circuit breaker, how does it work, and what’s it supposed to accomplish?

What is a circuit breaker?

It’s a market mechanism designed to reduce panic sell-offs and encourage orderly trading.

How does it work?

In the event of a significant decline in the S&P 500 from the previous day’s closing price, during the regular trading session (9:30 a.m.–4:00 p.m. ET) trading halts for 15 minutes or for the rest of the trading day, depending on the severity of the drop and the time at which it occurs.

What are the three levels at which circuit breakers are triggered?

  • Level 1: 7% decline; trading halts for 15 minutes unless the halt occurs after 3:25 p.m.
  • Level 2: 13% decline; trading halts for 15 minutes unless the halt occurs after 3:25 p.m.
  • Level 3: 20% decline; trading halts for the remainder of the day

What happens to my investments if trading halts?

Nothing happens to your positions. They just cannot be bought or sold until trading reopens again.
