Trading Halts and Circuit Breakers
Exchanges can pause trading in a share, or the whole market, to let people absorb news or calm down.
Why this matters for beginners
Understanding this helps you stay calm and read price moves correctly. This is general education, not personal advice.
Main explanation
A single share can be halted before big news, like a takeover.
Circuit breakers pause the whole US market after very large falls.
During a halt you cannot buy or sell.
When trading resumes, the price can jump straight to a new level.
Example using a real company
US circuit breakers paused the whole market several times in March 2020.
- →Share halted for 30 minutes, resumes 15 percent higher on a takeover offer.
- →Market falls 7 percent: trading pauses for 15 minutes.
Common beginner mistakes
- ✕Expecting to be able to sell at any moment.
