What Is a LULD Trading Pause vs. an A-Share Limit-Up?
A LULD trading pause is a temporary interruption in a US stock’s trading under the Limit Up–Limit Down price-band mechanism, which addresses extraordinary short-term volatility. Unlike an A-share limit-up or limit-down, it does not set a fixed maximum daily gain or loss: LULD bands generally move with recent prices, while A-share daily limits generally reference the previous closing price.
