Reaching peak marks the zenith of an event or situation. Alternatively, hitting a low or a trough represents the opposite of this. Antonyms for "reaches peak" include "lowers," "descends," "dips," or "plummets." These words suggest a decline, a fall, or a decrease rather than a rise or a gain. They represent an opposite force to the momentum of reaching a peak, marking a sense of failure, disappointment, or frustration. When a peak is reached, it does not necessarily signify an end; therefore, its antonyms imply that the end is close or even that the end has already occurred.
