ماذا يحدث عندما يكون السهم على العتبة؟

Could you elaborate on the implications of a stock reaching the threshold? I'm curious about the potential market reactions, regulatory oversight, and any possible impact on investors. Specifically, how does this threshold affect the stock's price movement, and what measures do market participants typically take in response? Additionally, are there any specific thresholds or regulations that investors should be aware of in order to make informed decisions? I'm keen to understand the broader context and implications of this phenomenon.
