Cyclical trends refer to patterns that repeat over time, often influenced by economic, social, or environmental factors. These trends can be observed in various fields, such as economics, where business cycles of expansion and contraction occur, or in fashion, where styles come back into popularity after a period of time. Understanding cyclical trends helps businesses and individuals make informed decisions. For instance, knowing that certain products may sell better during specific seasons can guide retailers in their inventory management. Similarly, recognizing economic cycles can assist investors in timing their investments more effectively.
