Reversals refer to situations where the expected outcome is turned upside down or changed dramatically. In various contexts, such as finance or sports, a reversal can indicate a shift in trends or momentum. For example, in stock trading, a price reversal occurs when a stock that has been rising suddenly starts to fall, or vice versa. In psychology, reversals can also describe changes in behavior or attitudes. For instance, a person may initially resist a new idea but later embrace it after reconsideration. Understanding reversals helps in analyzing patterns and predicting future developments in different fields.
