What is the Limit Up Limit Down Rule?
By imposing these price limits, exchanges aim to prevent extreme price swings that can be detrimental to market participants and the overall functioning of the market. Limit Down is the opposite of Limit Up, which is the maximum amount by which the price of a security can increase in a single trading session. Both Limit Down and Limit Up levels serve as circuit breakers to prevent extreme price movements in securities. Conversely, a Limit Down is triggered when a security’s price drops to a predetermined level, marking the maximum allowed price decrease in a single trading day. Similar to a Limit Up, this mechanism either pauses trading or prevents further price declines beyond this threshold. The Limit Down is designed to prevent panic selling and ensure that market participants have time to assess their positions and the market’s direction.

But semiconductor chips are produced by the millions and are small and easily concealed, and design software can very likely be moved across borders undetected. Chinese enterprises have already proven adept at smuggling proscribed chips through various forms of subterfuge.
